NEW FULL VERSION video created from my original videos plus step by step instructions of how to remove the ECU and fix a bad MOSFET with before and after videos for Mercedes W208 CLK and SLK.
MOSFET part: BUK101-50GL
Shows the symptoms of a CLK 230K, 2000 year with the supercharger always engaged even at idle, but it should be still until you reach about 2500 revs. If I disconnect the connector to the supercharger then the supercharger stops, plugged back in and it engages again. The by-pass flap also does not function. All happened from when an ignition coil blew.
Video shows how to remove the ECU and take it apart to access the bad MOSFET and replace with credit and thanks to :

Nice work! Thanks for posting My SC clutch is not engaging at all and the bypass air flap is not closing. I will try your MOSFET fix and check the signal wire to the ECU. My scan tool allows me to engage the clutch. It does not let me close the air flap as it's non responsive same with a spare used air flap.

Thanks, I just fixed my Benz following your video. Still is hesitant to accelerate but now the compressor clutch disengages on idle and the bypass valve closes on hard acceleration. The clutch also engages on hard acceleration.

Yes, but I have a question. Car works great of I don't step hard on the gas, but if I do, it starts to idle poorly, shuts down, and I shut it off, wait some time, start again and can move for a minute then does not want to accel, etc. I disconnect the MAF start a couple of times, let shut off by itself then reconnect and works good again until I demand hard acceleration. What could it be? No codes.

Have you checked your fuel rail? They can get blocked, I would use a scanner and get codes rather than spending more money at this moment. Good luck

@GrooveOn 3 жыл бұрын

What happened to me was a coil pack blew on a plug and then my supercharger stopped as it blew a MOSFET on the circuit board. The symptoms that the supercharger then has was it did not engage or turn on .

@@megeorge4128 It was a fluke, you should be fine. 150K is normal mate for a Merc, I had 200K on my old CLK, the only reason I dont have it is someone hit the back of me! I now have an SL 3.7L and use it daily doing a weekly commute of 400miles each way! she has 160K on the clock

You Sir are a LEGEND, very well put together video!!! I think I have constantly locked SC clutch also - I have also the code P0806 "comp. magnetic coupling." W202 1997 C200K 141kW. Now Im surfing the net what could be the problem and this video will surely help if I have this problem. I noticed that your CLK was pre-facelift? Same conifg. as mine. So do both these cars even have the K40 relay unit where the soldering points burn off? Because from looking at your video I dont see it. That would mean that either my clutch is shot (unlikely as my car is only 54k km) or I have same ecu mosfet issue that you fixed.

Hi there, I recall the K40 relay was more of an issue on the SLK , not the CLK..

Im on the 3rd mosfet. The clutch is working fine with a battery. I took it off to give it a visual inspection, but it looks fine, but it keeps blowing the mosfet even without connecting the clutch. Any ideas?

I found it was a voltage spike. Did you protect edge of MOSFET to avoid grounding?

@GrooveOn yeah after using the 3rd mosfet I installed the ecu and connected a test light instead of the clutch and worked plugged the clutch in and blew so the coil must have a short. Can't find a new coil anywhere

@GrooveOn 2 жыл бұрын

@@standolfo Hi there, the bi-pass valve should be open without movement, the slight movement doesn't sound quite correct. The valve should close around 1200 + revs if the valve is not engaging until really high revs, then I would look at possible changing it mate? (should be some second hand on eBay) if you have a MBStar you can open and close it through the software.

BUK101 - 50GL is identical to the DL but short circuit load protection max. is 20v, the DL is 35v but the switching rate is faster. Differences are minimal and should do the job. The "G" denotes a higher standard of component.👍
