VW RCD510 STEREO UPGRADE AND DREADED BATTERY DRAIN PROBLEM PART 2
Vložit
- čas přidán 8. 09. 2024
- Have you upgraded your stereo? and now suffer the battery drain? If Yes - You need to identify the CAN + and CAN - lines that come out from your stereo. Cut them, and link them up to the climate CAN wires. I accessed these from the back of the A/C knob panel.
The car has serval different CAN buses. The newer stereos required the CAN signal from the climate CAN-BUS, the signals sent by the orginal CAN wires do not shut down the stereo completely.
Please bare in mind there are many different setups, colours used and different connectors. You would need to research your ones (search for "pinouts") Only make new connections when the power is off, and double check any new connections before powering up as it is fully possible to blow your electronics system. Hope this is helpful
Hi everybody.
We bought VW Passat B6 3C2 recently with old stereo in it. Upgraded to RCD310 and we also had battery drain problem. But we fixed it thanx to this video. We have climatronic in our VW but the colors matched as well on that plug.
Thank you very very much!!!
Wish you all the best.
For anyone wondering, this also works on a Mk5 gti with dual zone climate control, the harness is a little different however the colour of the can cables is the same. Worked for me 2007 golf GTi w/ rcd 330+
Just carried out this modification on my mark 5 golf gti replacing the radio unit with a newer oem unit, worked a treat. As mentioned in the video the wiring connections at the ac module side is slightly different but lots of wiring diagrams online to correctly find can high/low. Much appreciated!
Hi, I am planning to do this on MK5 GTI 2007 any ides regarding which wires to rewire?
Same here please respond would like to know the wiring from high and low to correctly connect it to the can from the ac
This worked great for me. For 2 years i used the fuse box mod that didn't hold memory. Now i do a 2 mile journey 4 times a day not having mp3 or cd memory was really starting to grind my gears. I was looking at Chinese replacement head sets and found this i am more than impressed.
Great video...
This problem will accure in all mk5 Golfs, passats.
Also the stereo will come on without ignition on
My dad had his 06 Jetta TDI stereo upgraded to a touchscreen VW one with Bluetooth, ever since it's had this parasitic draw issue. I'm going to try this later on today and hopefully the issue will be fixed. Thank you.
did it end up working?
@@michaelshogbonyo3676 Yes, it completely solved the battery problem! No more dead battery in the morning.
@@NFSCalex And what color did the canbus wires end up being?
do you remember?
@@michaelshogbonyo3676 i think it was the same colors as in the video, the stereo should have a wiring diagram showing the CAN+/CAN- lines
Best solution I’ve seen. I bought the quadlock adapter but it died after 3 weeks. I will try on my scirocco and I already know it’s gonna work.
Thanks.
Hi. Thanks! I hope it did work for you, it's so nice having the better stereos!
Brilliant video thank you for sharing your knowledge/findings!
worked for my 2006 Passat 2.0T with stock premium 7 unit and I went with a 9" Android Chinese unit, had battery drain....car wouldn't go into sleep mode.....did this exact re route of can hi and can low wires and it's been a month soo far with no current being drawn from car after doors locked and around 5 min pass.
Hi friend, I have the Same issue with my 2005 passat b6, also steering wheel controls do not work!
I need to solve the battery problem first and I need help with the color of can+ and can- of the AC.
Can you help me?
@@mmk958 Your Canbus hi and low will be different than mine as i have a 2006 B6 model, First you to check your wiring, if you have a canbus box provided with your radio then plug it in and remove the red and black accessory plug. These radios all have a few ways of installing it. If you have the canbus box setup and the accessory power removed then you need to start your radio, go to settings, and change your canbus decoder to one that matches your car. If when you remove the key the vehicle screen does not shut off then you have a issue. It should turn off when key is removed and then go into sleep mode after about 5 min or so and have no power to it at that point..... Get a wiring diagram for your climate controls and find which wires are can hi and can low. If the first things didn't work that is the next thing you have to do... B5s are different and I'm not sure if all this works.
@@mmk958 if you have a passat with manual climate controls then it should be the same as this tutorial but If you have auto climate controls its a completely different story.
@@ArfanZakeri88 yes I have an automatic climate control and the new unit is rcd330 deesay 187a, it did not come with an adaptor or a can box like the ones with android unit.
I've done this few days ago and it looks good. Also steering wheel controls works good. The main problem is that I've lost the rear camera :( Passat b6
Yeah you'll need the can system for the stereo to tell it it's in reverse etc. Best bet is to either upgrade the can gateway or fit a relay on the yellow wire to switch on with the key. You'll lose settings though doing it this way.
You can connect the positive cable from the cigarette lighter below the AC, easier to find. Cigarette lighter will completely shut down the voltage once you pull the key out of the ignition. Also if you experienced the the battery drain, dont forget to fully charge the battery after the repair.Alternator wont do it. I had voltage drops in the rain resulting in restarting my chinese android unit randomly. Took me months to fix it with the simple battery recharge.
What do you connect that cigarette wire to?
@@candyman9816 To the positive wire,its a remote +12volts wire on your android unit
It worked like a charm! Thank you so much for the tip :)
@@candyman9816 Im glad i could help.
@@candyman9816 Im glad i could help.
Thanks a lot, i will try this on my jetta 2006 wich has a flat battery every morning since i use the rns510.
Thanks from the netherlands.
Thank you very much!... no more battery drain on my mk5 golf with rcd510!
The Dreaded red wire issue! I've just fitted a aftermarket xtrons unit which had the quad Iso harness type for my car provided.. did it work, did it sh*te! lol.
I'll keep you posted on my progress over the next few days! I had looked into this before jumping in and actually doing this for myself so this video has helped me loads
I found my 2din unit didn't even power up so i thought the red wired belonging to the quad lock iso harness needed to be re-wired to a AC feed from the dashboard fuse box by piggy backing a fuse rated the same as the stereo itself??
You're further into this than I am and we;#re way over a year down too!
hope you're well and thanks for the vid! :)
Do you have a multi meter? You would need to check the voltages on the wires to confirm if they are live, and weather they are switched. In this video I modify the can bus to make it work. It sounds like your having issues with the power supply? Be careful as you could blow a can bus module if connected wrong and that could cost BIG money to replace
@@DanSohan I do have a multi meter yes, like you pointed out I think this could be too risky where fitting this unit is concerned, the seller is giving me no support at all and it's meant to be plug and play according to the quad lock and I so harness descriptions given.
The unit is a android type with all mod cons on board which I don't know could/might affect the installation but I'm erring on the side of downgrading to not as good good but fit for purpose type.
My suspicion lies in the feed from the ACC using a piggy back fuse set up but after trying last I've blown a fuse belonging to the unit, in the engine fuse panel so I'm a bit wary now for a multitude of reasons all to be honest unknown to me.
Great work in your video btw, very creative!
This worked for me although my wiring was different I found the green and brown wires was the cam wires at the back of my stereo great vid tho👌
Do you have a climatronik or manual ac?
@@mwolf8863 I have the climatronix control unit
HI, done this before , much easier to add the device to the can Gateway with VAG COM ,through the OBD port.
nice little mod if you dont have VAG but do have time to pull apart console.
Phil dabandil we have vag com, but the can bus gate way module was of a version not to support this stereo. Could have bought another module but decided to try this while the stereo was out. Still working fine, but maybe a mod best left to someone with experience in wiring.
@@DanSohan when you turn on the radio manualy, it will turn off automatically or it stay that way all the time? If doesnt come off automatically again then i think i have to go with vag com and new gateway module because childrens always mess with the stereo and leave it on.
@@chancho00 it works as it should. If you turn on the radio while the car is still powered up it will automatically turn off when the car powers down. I.e the keys have been removed for around 5 mins. After that it wont turn on again untill the keys are inserted
@@DanSohan I just done the mod, installed the model RCD330+, i just notice that if you wait those 5+- minutes the power goes to zero amps but if you open a door or activate any button from the remote control the the 5+-minutes cicle start again but goes down again by itself, in my case i can turn the unit manually without the key inserted so i have to be careful that me or anybody doesn't press the power button when i go out or the unit stays on the whole time even when i lock the car(something curious is that some functions are disabled like bluetooh, even the unit show a message saying that i have to turn the ignition on to use it, the radio works fine), also i notice that the rear camera sometimes doesn't want to come on and the unit says that rear camera is unavailable, it dint happened on the original can bus wires but at least the batery drain problem is fixed
Thats more complex than our system, no bluetooth or rear view camera installed. I'd imagine they run from the other CAN Bus maybe. maybe the only way to get it working 100% in that case is a new gateway
It is same for mk5 golf incase anyone is wondering
That's good to know!
To really stop the battery draining change the power circuit to the cigarette lighter circuit that’s completely off with the car key when you stop the car. Take the circuit from the fuse box with a piggyback from cigarette lighter fuse to the android unit instead of the harness power cable
How do you do wire managing with that? Run it behind the fuse box to the cigarette lighter ? (Vw 08 eos) mines located under the radio
Great video.
Can you answer me this, after you lock the car and wait 5 minutes or more for the current to drop to 0A.
Can you still turn on the radio with it's power button?
I'm taking NO key in the ignition and the car is locked for sometime.
I'm not 100% sure, but I will try and check later when I get home!
Sorry
I didn't get a chance to try, but the other half thinks the alarm might go off. I think if the roof is down in the internal sensors don't come on. If the roof is up the sensors will be active. It's been raining so not wanting to put the roof down to try.
@@DanSohanyou have to suffer for your science....or is that your art. 😊 .
Wish i understood what you did here as I have the problem in my caravelle. Had to just disconnect the stereo. What does "get a new canbus gateway" mean? Thx
I've been experiencing radio coming on as and when it wants and draining the battery within a few days - whilst I was monitoring when it came on, I noticed it didn't if I left a cd in - not sure if this problem is unique to my mk5 golf only? It's now over 3 weeks since discovering this any my radio doesn't come on randomly and drain the battery anymore - great!! Hope this info may help someone somewhere? Quick fix!!!
Trying this haha hope it works less wiring
Hi All,
Wondering if anyone can help! Installed a 9” Android head unit Essgoo (Chinese) in my partners MK6 Golf. The headunit wouldn’t turn off initially so I read up and noticed people mentioning disconnecting a red and orange connector supplied on the head unit loom. I did this and the head unit now turns off when I take the key out. The issue is I went back to the car this morning and the battery has died???
I know the unit shuts down fully after approx 5 minutes as when I turn the car back on with key etc the stereo shows my VW logo and Android logo and boots up.
My main question is it’s obviously draining the battery but does anybody know how?
Thanks 1000 times my issue is resolved
hi thanks for this trick.can we connect b+ wire directly to fuse also instead of this?
I've seen that on some cars, the blue wire ( power antenna) is the culprit...
The Chinese unit, keeps spending 12 volts, even when the unit is off...
Will have to do a bypass to the cigarette lighter, that powers with the key on
mine is Chinese should i do what you mentioned with the cigarette lighter. just because my Pontiac had a blue wire and i matched it like the instructions said , my new stereo isn't ( opening the switch ) to stop voltage from going to the (power antenna)
That's why it keeps draining the battery. the power to the antenna is never cut down...
It happens mostly on Chinese units
Use an multimeter to check the voltage consumption
good. Very good video but I have a doubt.
Do you waste time and saved stations? is that if you cut power the radio would not have for memory.
I am waiting for your response, greetings.
Hi, thanks for saying hello. This fix made our stero work like it should. The stations are saved as they should be. Only disconnecting the main battery causes the radio stations to be lost. We still have the car now and all works correctly still. Good luck
do you think this might work for a transporter t5.1 with drain problem with chinese after market can bus communication plug?
@Dan Sohan
Hello! I have exact the same problem with my 2007 Jetta. So What do you think, am i going to solve my draining with that? I have RCD 330, which has not the CD player, which is The problem in your video.
Hope you answer!! Would Be so helpful!!
Hello Arttu. I'm sorry I cant not confirm if this fix will work with your RCD 330. The Jetta is basically the same as our EOS so I think you will have CAN wires to your AC controls? If you are ok with finding the wires and cutting them it might be worth a try, but only if you know what you are doing as you could cause things yo blow. Maybe ask a car technician to try the fix?
Yeah, i think thats The worth of trying😄 sure the AC works If i cut those wires?
@Dan Sohan
So did your AC work normally after that? Im curious to know, because i live in Finland, where that ac defintely need to work😂
@@arttu_laakso you dont cut them. You join them as far as I remember. Cut and rejoin all together
What about connecting the light switch to the whole radio and then the radio is on only when the light are on? Do you think i should try?
Where can i buy this bypass for my 2006 mk5 jetta? Great video though. Cheers

Hello I am from Argentina. my vehicle has steering wheel commands. When cutting the CAN BUS of the stereo, will I not lose the steering wheel commands?
I dont know the answer to that. But please let us know here if you can test or find out.. I think the commands might use their own wires, but I'm only 50% on that. Hows thing in Argentina with the virus? Stay safe.
@@DanSohan
I did the video, my vehicle stopped showing up without load the next day. But, if I don't use it for more than 2 days the same thing happens again. Therefore, this solution was not 100% effective for me :( Regarding the commands, the volume ones keep on going, but on the dashboard screen it no longer shows me the music, nor can I change the song.
@@DanSohan Let's say we're fine, we're taking it responsibly, at least until the vaccine is developed. Here we see the news from the USA, and honestly, the attitudes of its president are repugnant. Be quarantined and wear chinstraps.
I wish you the best of luck in this nightmare.
@@maurosegura_ yes, best to be cautious and keep family safe until more is known. We're all safe here for now, keep well. Sorry this doesn't fix your problems, our car does not show cd info on the dash.
Give us feedback about the steering wheel controls and the battery drain.
hi, i bought a rns510 with built in canbus, what should I do?
I think in this case (if your stereo needs the other can bus) you will need the custom or reprogrammed cam bus gateway module. You will probably need to speak to a friendly vw garage or someone that knows the german car electricals
Hallo sir, what about the red light for the radio buttons? Does it turn off when you turn the lightswitch off? And on when you turn the lightswitch on? :)
hello, can I use your video for education purpose/knowledge/source of information and dispute.??I have the same battery drain after the dealer made a stereo replacement.
You certainly can, but please note. I am not associated with VW. This was a DIY fix and for the job to be offically fixed an updated CAN BUS gateway should be installed / reprogrammed
Perfeckt bro I use passat b6 volume up volume down mute okey but road PC dont work
Sorry, I don't know how to get that one working, but good luck!
What is different between CAN-BUS which comes in the Radio and CAN-BUS which comes into AC. Why I can't use Radio's CAN-BUS, why should make a bridge between the two units?
They go to different controllers or gateways. I guess the reason they don't use 1 single canbus is it might become overloaded and slow down communication. But essentially the engine ecu has its own Cambus, the AC has one and the internal instrumentation has one. Some have more.
@@DanSohan Thank you for the Response. I installed android radio and the battery drain fast. I will try your solution, but I am confused about why have a difference between units. Moreover, my android radio has CAN-BUS decoder which obviously doesn't work.
How to do this in my rapid / vento 2012 model plz tell
Interesting video, I have the same problem on my EOS with a new android Xtrons head unit, the lead connector comes with a Canbus but the battery drained on me.
Apart from your trick:
does the Fuse bypass trick Works also?
Can I hook it to the cigarette lighter?
Can I keep everything original but play with the Vagcom VCDS for the head unit Canbus?
I think the only other fix i know of working correctly and safely is the canbus gateway module needs to be replaced. But I dont know with which one, hence went with this trick. Still working fine now.
@@DanSohan I will try your method this weekend 👍
@@DanSohan
Hi again, thanks for your video again,
My question is. Where did you cut the Can low/high from? I mean from which side of the harness. The VW harness or the after market stereo harness. Or just two plain fly cables hooked into the vw harness side?
Sorry for these question as I'm not familiar with electronics... So far I'm pulling my hair with the EOS sunroof beign stuck closed and won't open when I press the button, the new motor gear still jumps teeths after beign replaced...
planning on doing this on a golf mk5. any advice or information you can share?
You can connect the positive cable from the cigarette lighter below the AC, easier to find. Cigarette lighter will completely shut down the voltage once you pull the key out of the ignition.

@@kamilkazmierczak2842 did you cut the posative wire from the stereo and put it to the cigarette lighter what did you do with the earth did you just leave it or do the same as you did with the posi thanks for the info
I have a 2014 Jetta that came standard with the boring looking RCD-310 radio. Wondering if I should even plan to swap my radio to an RCD-510 Premium 8 or not. Maybe since my car is newer, there shouldn't be any battery drain problem? I had a 2011 Jetta that had the RCD-510 come standard. Anyone have any advice? Maybe 2011 and newer models years won't be any more work than a simple swap and no programming of Vag Com?
I dont think you will have any power
it will drain your battery unless you install it the way he did it in the video.And its worth it!You tube, internet from your phone,amazing sound,better then on the original sysytem.Unit itself is cheap as well.Just install it correctly and you will love it.
if i understood,the climate CAN wires is in paraller conection with the radio's Can signal pins?The canbus of the climate works as it supposed to do?There is no problem if you connect two devices (the radio and the climate) to the same wire?
that is correct. No issues with ours a few years on. still working great.
@@DanSohanthank you very much!I did it on a vw mk5 and it works great!The current when the radio is sleeping,now is about 1-3 mA,before it was 130 mA.When i remove the key from the ingition in about ten seconds enters in sleep mode
@@AxelsTech great. :) glad it worked well. No more flat battery to worry about!
@@DanSohan after few days my climate pannel dosent work, when i put ingnition on the 2 little displays blinking with some logo for 10 seconds and then come to normal, the recirculation button is dead, the temperature is not working just the fan is ok also the zone buttons ⬆️➡️⬇️ dosent work anymore
I use vcds i and i have 9 error codes
But the most important is something about "low tension"
Do you think this method with CAN wires can damage something to my climatronic?
@@valentinstoica4319 sorry to hear this. It shouldn't cause damage as the CAN inputs have protection.. it sounds like a lost connection maybe. Might need to pull and reconnect.. or do a fully shut down by removing power for a bit. The original CAN radio wires need to be disused and well insulated from each other and risk of touching anything else when radio put back in.. to test the climate controlled. You might try disconnecting the stereo and returning the CAN to how it was before and if it functions normally after a reset. If not, there is a Fuse on the CAN system I think. Check them.. best of luck with the issues
is this radio a straight fit into a 07 passat? and will this battery draining problem always occur with this radio
t drains on my 2007 passat 1.9tdi
Is the unit not causing any problems no more ?
Nope. Shuts down perfectly. No battery drain even after 2 weeks away on holiday.
Did you fix the steering wheel controls problem?
Putting me off upgrading my headunit. Is there a head unit for a mk5 gti that won't drain the battery without faffing with cables? lol
Don't know, this was to cover the VW RCD units. I dont know how it works with other after market stereos
did the old stereo drain the battery when the stereo was off or was it draining when the car was turned off but the stereo turned on after the car has been locked? how is it possible that a stereo can drain a battery when the stereo is off? because i think my stereo is doing that to my battery, i might try this, its a Honda accord euro 2012 model
This mod is only really for VW as it's a known problem when you swap the original head unit for a new vw version. The issue is when the car is turned off by the key, a signal is sent on the cam bus wires to turn the radio off fully. The newer units receive a different signal from another can bus (there are a few for different core systems, e.g engine management or climate control etc) this fix sends the shut down signal that the AC receives to turn off the newer version head unit. I dont know what the issue is with Honda. It could be a fault unless you've recently changed it?
@@DanSohan yeah but you didn't answer my question. Did your stereo draw power from the battery when it was off? Because that's what's happening with mine i think, the stereo is off when the car is off but it seems to be drawing a lot of power from the battery even though it's off, it's weird, is that possible?
Have you got Facebook? I need to speak to you if that's ok?
The stereo is origional btw
@@r.k862Yes

Hi will 2014 touran 1.6 tdi have this battery drain issue if I change to rns510?

@@DanSohan Ok
if this is helpful, i am gonna look for you, i am gonna find you and i will offer you a beer!
I think it'd be easier to upgrade the can gateway and redo the long coding.
As long as you've got access to vcds absolutely
Can an aftermarket pioneer cd player drain the battery ? Does any body know any solution for aftermarket radios ?
Not normally. It depends if it shuts down from the main ignition wire or is controlled by cantus signals
@@DanSohan I fix it man , thanks. The parasitic drain turned to be the cluster
You should have just updated your canbus. It’s cheap and a direct swap, plug and play
updated canbus? how would one go about this?
The canbus module is under the dashboard. Newer revisions fixed the battery drain problem. You remove the old one and install the new one. You need to “code” the new one but it takes only a minute with a vag com
Did you try this out ? If so for what VW and did it work?
Antonio Maciel yes. It worked perfectly for us and no need to buy additional hardware
It’s cheap he says lol vag com is 200$ just for the 3 vin specific one
I have same problem prolly,vw touran.Bought new stereo and now my battery die's every fucking 2 days.
Did the exact same way... Still battery is draining... I figured out that battery drain is occurring only when the stereo is off before we switch off the car... If the stereo is playing and I switch off the car... The battery drain stops
Humm. So it seems like the stereo gets its shut down command when on, but not when switched on. Is the memory supply correct. Does it remember its saved radio channels ok? Im not an expert just found this worked on our 2007 vw car. Maybe you will need a can bus module upgrade. Good luck
@@DanSohan yes memory will be intact
devanandan K V is this the case if you don’t do any wiring mods and just install rcd510. I have a mark 2 Skoda that has the drain issue.
Why not simply upgrade the canbus unit to a later version?
Because it cost some money. This was free
Err what ?? What is can wire mean
If your not sure, it's probably not a mod you should try without much more researching first. There is a risk of easily damaging the whole car if done incorrectly/ joining the wrong wires.
The same shit happens to my golf mk5 I’m waiting for a solution cause I’m quarantine
Would this be the same for the mk2 Leon cupra 2007?
I can guarantee, but it is VW Audi so very likely. Let us know if you give it a go and works.
@@DanSohan I've found the orange/green and orange/brown wires on the back of the aircon unit. I take it these are the canbus wires?
So my radio loom for my android unit looks the same as yours, what colour is the canbus + and which colour is the canbus -?
@@cuprak1lad543 does it not say on a sticker on the back of the head unit. Would need to find a wire diagram somewhere
@@DanSohan they wires out of the Android unit are all labelled but it's in Chinese lol. I take it I've got the right coloured wires from the aircon. What colour wires are your canbus wires on your android unit?
@@cuprak1lad543 We dont have an android unit, it was a VW unit we installed.

I would recommend undoing the new connections and seeing if it fixes things. If not maybe you need an autoshop to take a look. Good luck
so i installed a Aigoss Car Stereo in my Pontiac Saturday by tues morning i went to to start my car and its killed my battery. My factory harness has a blue wire and theres a blue wire on 1 of the harness that came with the radio so i hooked it up. im not sure where im getting the continuous power loss from. where should i start. i had a few wires like a brown and light green one left over from the unit and an extra orange from the chime harness so i taped them off. what did i do wrong besides buying a cheap amazon pos lol
Need to know exactly what wires are what. Colours may or may not match up. There should be a permanent live to the memory and a switched live to switch it on and off.. on mine I thought blue was for an automatic powered antenna. I dont think the fix in this video will help much in your case, as this is based on a canbus issue related to VW VAG cars only.
Do your steering wheel controls work?
Don't have any :( Will be adding at some point so hopefully
But you will then get memory loss
schranzwar nope. No memory loss. It's been in for over half a year now. Works perfectly. No can bus reprogram. No gateways. A free and simple fixed worked perfectly for us. May not be the same in all cars.
I have vw passat variant b6
Dan Sohan what about can bus decoder?
@@schranzwarno pain no gain, i think you have to extrapolate for yourself what you can on this thread and go from there .. we can (pardon the pun) figure this out for ourselves.. we're intelligent enough! Aren't we!! aren't we??
