- If you drive a DSG, you will have a mechatronics unit controlling the gearbox for you. These are really intricate computer systems that make sure every gear change runs smoothly.
The issues occur when these go wrong. Let's take a look at some of the most common faults you can expect from your mechatronics unit with Callum, our Gatwick DSG expert.

Love the trolling of Callum with the drop counter :D
We couldn't let it go unnoticed 😆
Nice video!
Thanks! Glad you enjoyed it :)
Good video.Im thinking of buying a 2014 Fabia with 5 speed DSG which is a dry clutch.The car goes in to Drive but doesnt move off.Im suspecting the DSG clutch has gone as its just over 79000 miles so probably on original clutch.
Thanks for sharing. Can Anyone tell me exactly Where these are prone to leak??... Got a 2006, can't tell where the heck it's leaking from. Thanks. - take care
How do you release pressure b4 removing the pan cover i understand it is under pressure.
Hi @ccmgarages
My Škoda service advisor has diagnosed issue with mechatronics for loss of power whilst in drive and is replacing the accumulator in my ‘17 Octavia 1.8 TSI DSG (DQ200). I wanted to know if this is a permanent fix or a temporary one?
How long does the DSG/ mechatronic last after this fix?
Our DSG failed coming up to a roundabout the drive just disappeared which with large lorries thundering past we had no option than to come to a halt in a fast moving live lane - I think VW should have a class action taken against them, they have known about these problems for years but continued rattling them out - I’ll NEVER buy another vw as long as I live - oh and by the way quoted between £2,800 - £3,500 plus vat - I expect better from what was a reliable well built car.

Mine died while crossing a highway...with my toddler in the car 😂🫨😱
Ever seen issues where the communication to the tcu is lost periodically?
Something dealing with the megatronics gear box I just came from Mississippi this pass weekend no issues I drove it 7 hours no issues in paddle mode but will not drive in automatic someone help.
I have a audi a6 2013. My problem is that sometimes when I'm about to take off from start it takes about 3 seconds and jumps slightly. It has been serviced. Once it going no problems in sport drive paddle shift. Pulls like a train.
great video on the Mech Unit. A fellow youtuber(#entourage garage) and i are going to be putting a DQ500 in a 96 mk3 jetta. Right now we're trying not to void to much of the warranty on my mk8 R.
Thanks Rob. Sounds like you guys have your work cut out, best of luck to you! We'll go check out entourage too.
Great video, our car has just broken down (cut out mid-drive) and now wont start. Shifter stuck in P (unless I manually release it). Now started coming up with an ESP fault and wont try and crank (says please put shifter in P/N which obviously Ive tried). Im guessing its the mechatronics unit, what do you think?
Hey, it does sound like it may be an issue with the mechatronics however, without seeing the vehicle we wouldn't really be able to advise. The best thing to do would be to get it booked for an initial diagnostic with your local DSG expert and see what they think.
@@ccmgarages thank you appreciate the advice
You mentioned "they have re-design it " some parts of the DSG transmission so, it can last longer. From each year of the VW gen 5th we get it with the new design?
Hi Lee, they did change from mineral oil to synthetic oil. Allowing electrolysis separating sulphur from the the synthetic fail and its deposition causing electrical failures to the mechatronic unit.
Great content! Audio could be better but still understandable.
Any guess what might cause lurching slips under heavy acceleration in a Q5? I don't think it's shifting, feels more like a momentary slip.
Cheers for the feedback - we have some better mics now 😜 Honestly, it could be a number of issues. Your best bet would be to get it booked in somewhere for an investigation before it gets any worse. The longer its left, the more damage you'll be facing
Hi, I have a Skoda Octavia automatic, 2017, can you tell me please how much oil goes into the mechhatronic? Just replaced the gearbox. Thank you!
1.1L
My pumps staying on I hear it buzzing constantly what causes that
My 1.2 polo GT TSI DSG doesn’t creep forward when slotted to D gear
But the reverse creep function is working.
The VW service center said they couldn’t find any error code in the scan and also said doing a base setting reset using VCDS scan can harm the mechatronic unit as I have changed the battery outside of VW.
Please suggest.
ooft, sounds like you've got your work cut out. We wouldn't be able to suggest anything really without seeing the vehicle so we'd recommend taking it somewhere where they can do a proper investigation for you.
I have passat b6 with 7 speed dq200 and it has one fault code, its p178b. Car cant be moved and hydraulic pump is 100% not working. Is it TCM or pump itself?
Hi @stefangavrilovic8355 it could be either that is causing the problem for you. Without seeing the vehicle and testing it ourselves its impossible to accurately say what the cause is. We'd strongly recommend getting this recovered to a garage and sorted.
Family member with failed Mechatronix on 2021 VW Tiguan 1.5 tsi. What year have these been modified and improved ?
We are seeing all years of mechatronics coming in, it's not just older models
Do you think VW will have addressed this common failure
It is something they are definitely aware of, wherever they are designing a fix we simply don't know 🤷
I have a 2018 RS3 DQ500 with 100K miles on it and on cold start the car won't shift into drive until the car is fully warmed up (5-10 minutes of idling), if I put it in drive when cold and give it just a little gas (maybe 1200-1500rpm) the car will slam into gear and lurch forward. Do you think this is a mechatronic problem and if so why would it only do it when cold? Thanks for any ideas.
Hi @Elijahallen - it could be a multitude of things but our first question would be has the gearbox ever been serviced? If not, we would highly recommend this. We are able to do a automatic gearbox flush which makes a huge difference to the driveability. Check it out here > ccmhelp.co.uk/services/gearbox-flushing/
If the issue continues, it could be the clutch, mechatronics, the gearbox - anything! Without getting the vehicle up on a ramp and having a good investigation we wouldn't be able to advise any further than this
@@ccmgarages Thanks for the reply. We have it in the shop now with the mechatronic unit pulled. There are several torn o rings on the hydro tubes so I'm hoping that is the problem.
I have a 2007 Jetta 5 2,0fsi bwa engine dsg gearbox it doesn't start it only cranks and flicks PRNDS on the dashboard what might be the problem
It could be a multitude of things unfortunately! Without getting into a garage and having a full diagnostic scan, its near impossible to suggest what the fault may be
Was it position sensor?
Hello am getting trouble with passt dsg doing hard shifting can you help me out
Hello, without seeing the vehicle its impossible to provide any advice as it could be a multitude of things causing the issues you are experiencing. The best thing is to get you booked in for an initial diagnostic and we can then put together an action plan for you
Would you recommend getting a dsg ? Been looking at the 1.5 leon
Hi Luke, yes we would recommend a DSG as they are really intelligent gearboxes but it is worth being aware of the issues that can arise as these quickly run up costs.
The best thing to ensure a happy and healthy car is always to remember the importance of regular servicing, maintenance and getting any issues checked out quickly before they start to progress.
@@ccmgarages do you recommend getting the dry 7 speed clutch serviced ?
@@GameWithViiP3R the dry gearbox which is a DQ200 theoretically has no service points unlike its wet box DQ250 which does have service schedules due to oil being used in the clutch system.
@@ccmgarageswhat about DQ200 servicing in real life? Should it be performed and at what milage?
I have a 2013 audi q5 2.0t premium plus . I just lost all gears i can shuft into PRND but if i put it in park the car keeps moving almost as if every gear is nuetral could this be a mechatromucs issue ?
Yes, possibly. The mechatronics is the brain of the gearbox so if this has failed then it could be causing the issues you are facing. The best thing to do would be to get your car booked in for an initial diagnostic and go from there
@ccmgarages thank you. I'm having it towed today to get a diagnostic done . I also forgot to mention if I keep my foot on the brake without releasing it and go from drive into park make a noise like a baseball card in a spoked wheel as if the transmission is driving even with the car not moving
@@angelnieves4929 no problem :) Hmm that sounds strange but yes, it definitely sounds like something is going wrong there. We hope you get it sorted!
My unit is not cracked but I changed it but still oil is leaking through the breather what should be the solution now,which seals to change
Yikes, it doesn't sound good. It may be that you've added to much oil and its now overflowing. Best thing would be to get it to a skilled DSG specialist
It seems that the control unit is in good condition😁
Hi recently had my mechatronic changed on my Audi a3, but car still isn’t driving. Parking gear is blinking and transmission isn’t picking up on scanner. Please help
Yikes, sounds like something definitely isn't right there. It may be that they haven't properly coded the new mechatronic to the gearbox or possibly, if the clutch is highly worn that can cause issues where the mech unit isn't happy until that is replaced too. If I was you, I'd be taking it straight back to where the mechatronic was replaced and asking them to look into it again for you. Or call our team and book in with us :)
@@ccmgarages what’s strange no codes came up signaling an issue. If the clutch needed replacing wouldn’t there be a code? I remembered when the guy placed new mech in he receives a code low pressure, he realized mech needed more oil. After placing oil, that’s when malfunctioning started and that’s when he lost transmission communication. So I highly think it wasn’t properly programmed or something wasn’t done right with the oil installation. What do you think ?
@@ccmgarages got the problem solved. But another came up. reverse gear is engaging but car is not accelerating in reverse. And it seems to be stuck in 2nd gear. Any suggestions?
Why is it mechatronic unit give issue? What the cause of it? And how to maintain it. I know its not cheap to replace it.
The mechatronics unit deals with gear selection and is a complex unit with its own TCM and oil supply. A common fault is an ingress of Sulphur from the main gearbox causing degradation of the mechatronics unit and penetrating the TCM, causing electrical faults which confuse the gear selection process. In this case, you would need a replacement mechatronics unit and not a whole gearbox and mechatronics unit combined.
A good way to maintain a healthy mechatronics unit is to ensure you have regular servicing of your vehicle so you can spot any worrying issues early on.
@@ccmgarages hey thanks man. Will keep this in mind. I'm planning to get scirocco 1.4 tsi twin charge so I'm carefully doing my research to understand the Car main issue.
No problem @@PJWALL89 happy to help 😄Just make sure wherever you go has the facility to reprogram the gearbox after doing any work. There's a lot of places that can do the 'mechanic bit' but don't have the programming tools
Change the mechatronic, it may break down again?
Possibly. The mechatronic should come with a warranty so you would be covered
@@ccmgarageswhich insurance or warranty would you recommend that would fully or almost fully cover the mechatronic?
Hi @@thobanimanzi this isn't something we'd be able to advise on, unfortunately. However, if you have a new mechatronics fitted, this should come with at least a one year warranty
Terrible idea. Either they came up with something designed to fail or they just over designed a system that worked fine. Eventually we will get back to simple, well made cars. Not these overly egineered monstrosities with more crappy sensors that put your car into limp than soft mick
Better to stay away from cars with this type of gearbox. Repairs are very expensive!
Yes, they are expensive to repair, but so are most parts on modern cars simply because of the amount of tech within them. A wing mirror historically was just a mirror, but now it's packed with sensors and tech.
We obviously see the worst cases working in this industry but there will be thousands of mech units that live happy long lives without needing any repairs or replacements. The key to not getting a big repair bill is to make sure you properly care for your car!
@@ccmgarages Maintenance was done by a official VW workshop only. Drove normally with the car. But it still got a crack in the housing of the mechatronic...
@@stefan2796we're not saying mechs never fail, but you've got to admit they are clever pieces of kit!
@@ccmgarages i'm not going to buy a car with a DSG gearbox again...ever...
@@ccmgarages i buy a used remanufactured dq200 on Amazon when i install it it not picking up on my scan tool lost communication with tcm ?
