I reckon the r170 is the nicest car I've ever owned.
I think my r170 is in the worst shape out of all my Mercedes but I still love it the most I’ll take it out over the clk any day
You can't get new replacement electric clutch any more they are not made. If your electric coil is burnt out (close circuit, shorted out , or open circuit,) you need something with the same resistance at 12v to give the correct amp draw to fool the engine ecu that the electric clutch is still there to enable the boost control bypass valve to operate, otherwise the bypass valve stays open and you burn out the MOSFET (power diode ) in the engine ECU. I had to repair the MOSFET in the engine ECU because the previous owner drove the cars a lot with a faulty clutch electric clutch coil.
The engine ECU is coded to the immobiliser and the the immobiliser is coded to the chip in the key fob, so changing the engine ECU means changing to the matched ECU immobiliser and the ignition key fobs.
The keys can be swapped with the original key as hey are held in the fob with a small roll pin, so changing the locks is not required.
Do you know what to put to fool the ECU,my electric coil burned and now I make it fixed clutch and take out electric coil and now my bypass valve is always open,there was also burnt fuse and asr bas light on,and i changed it and no more light but bypass never closes so i need something to fool ecu,I see you know about that stuff and do I need to change mosfet?
@@ramadansimnica1724
yes you need to cha ge the burnt out Mosfet o side the engine ecu.
the mosfet is about 50p and you need a low wattage small soldering iron and a melted solder sucker to draw away the melted solder.
I never found a way to fool the ECU..the only way is to get a second hand clutch windings and mount it by the air box and replace the clutch with a fixed drive pulley . avaliable as aftermarket.
it is difficult to fool the ecu about the clutch windings I tried resistances etc without luck and they get hot.
when fixed the bypass valve works correctly
fix it quick before the mosfet in the ECU burns out !
nothing I know of to fool the ECU that the electric clutch is there..tried big resistors etc...the only thing is the clutch coil ( not open circuit or short circuit) mounted by the air filter. and a fixed supercharger pulley
So I’m kinda late to this party but how has this car been running now 2 years later? I’m getting ready to do mine but I’d love to hear how the car runs after putting miles on it.
Is your engine the same as mine which is a w202 c230k 2000 looks like the same engine from your video. How long did the job take? Cheers
It's not a big job to do
Wondering if you have experience with running this AND a larger crank pulley together. If so, did you need a shorter belt or does the tensioner take up enough slack?
No sorry only ever changed the one pulley
According to the internet if you do a bigger crank pulley you need to change alternator pulley too so you don’t overrun it being in the same belt
Removing the clutch will remove the way of regulating the charger when idling. The charger will eventually will die due to this as there is no way to bypass the air in this case stopping the charger to keep it cool.
Then explain how hellcats superchargers are clutchless and works perfectly fine🤷♂️
The face-lift r170 are clutch less i run this for years like this with no problems in fact its still going without problems.mercedes only put the clutch in to try and be fuel efficient but it didn't make much difference so they didn't bother when they did a face-lift
Nice video,
Buying a pully next, for my C class.
So basically just loose off the original pully?
Do you have to slacken off the belt??
Thanks
thank you
I fitted a fixed pulley like that on my c230 kompressor and now the supercharger is rattling at idle
Doing mine tommorow. Wish me luck. Excellent vid by the way.
Where did you get the pulley?
Hello
Tempted to do mine and maybe crank pulleys if u can buy the set..?
Hi, I'm waiting to get mine delivered, thanks for the tip! :) Anyway, maybe a stupid question and already sort of answered here: I know you didn't remove the SC itself, but just to make sure, I heard you need to remove the metal pipe that's in front of the pulley in order to be able to fish it out - do you by any chance remember if that was the case or is it possible to fish the old pulley out without removing anything else whatsoever? Thanks!
Thanks for the like Chris, but an answer to my question would be even better :D O:)
I'm sure I didn't remove anything just pulled the pulley off and relocated the magnetic clutch part to keep the ecu happy which you need to do or it doesn't boost
@@CarChris82 Thanks so much for the answer and sorry for bothering you. :) My pulley arrived and you gave me hope that the job will be far less annoying than advertised by other people :D
No worries I found it pretty straightforward just take the pulley off and then relocate the centre bit that has the wire on and refit the new pulley.job done 👍🏻
Did you pick the mm size??? …or can you go smaller
I choose the size what was advertised but you can ask for different sizes
ayeeeeee nicer!
what about your clutch pulley whatd you do with the light? interesting,
I'm going to try and figure somthing like a little lightx that turns on instead of the magnet.
I removed the clutch pulley
What light are you talking about?
@@CarChris82 you had kept it plugged in. I removed my overdrive pulley, that thing is stupid. absolutely stupid of me to have done that -__- but yeah, was my first mod I guess. Mine isnt long enough to do that over there. I got mine from turkey on ebay.
how hard was it to get the old one off ?
Hey chris. I`m woundering if there is still posibility to buy this pulley, as the link is dead....
hi mate i just put a link to the seller in the description so you can contact them to see if they can make one for you 👍
Hello, what diameter have you machined this pulley so that it does not damage the motor and the compressor?
Hi mate its 84mm there is a link to the pulley in the description 👍
@@CarChris82 oups I did not pay attention. Do you think a diameter 75 would be too much for the motor? Thank you
@@TheChristophe057 It should be OK but I think a few other things might need to be changed aswell as it would be making a lot more boost you would have to look at a smaller belt and maybe have the fueling adjusted.thats why I went 84mm and kept the standard size belt and just
@@CarChris82 Thank you. I intend to remove my magnetic pulley which is defective and replace it with a fixed pulley. I saw that you had to trick the computer with a resistance so that the pulley was driven all the time. I imagine you have to remove the compressor to remove the crimped pulley and install the new one.
@@TheChristophe057 you don't need to remove the kompressor I just pulled the pulley off and relocated the magnetic clutch part with the power going to it 👍
Do I need to modify the ECU or other modifications to mount this kit?
I didn't I just put a bigger fuel pressure regulator on
@@CarChris82 what is the old vs new pressure?
Will this work for the 1999 c230 Kompressor?
Yes I don't see why not along as it has the same engine
Hello Car Chris great work.....😉 where can it buy?...i'm from germany. thanks
Use the link for the seller in the description mate 👍🏻
@@CarChris82 thanks 👍😉
@@oldmercsneverdietheygofast5820 no worries 👍🏻
where i can buy it? no problems with EPC?
I did but a link in the description and no problem with the epc 👍
which belt goes there? with 83 pulley?
I just put a new standard size belt on mine
@@CarChris82 keeps the idle well with the compressor always on?
on the magnet did you add a fuse?
Yeah you can see in the vid it makes no real difference
No because I kept the original circuit just relocated it
