Air flow meter, also called a mass airflow sensor, mass airflow meter, airflow sensor and various other things! It's the meter of air entering the engine and was covered in oil, no doubt PCV system will need a look at next
After a bit of digging the 98 model doesn't implement OBDII, it is Mercedes only so no diagnostics for me. I tried the LED but that didn't work either so its carsoft or STAR if you find yourself in the same boat as me
Well I managed to fix it. I figured the AFM or cam position sensor were the most likely suspects for causing the ECU to fail to trigger and for £20 I could afford to try it out. The AFM was changed and immediately boost was restored. I even put the clutch back to ECU control and it's all good now
I am indeed stabbing in the dark but I have no way of getting the codes, this is one of the intermediate years from some reading which means you can only get codes with Carsoft and the 38 pin connector which I don't have.
Correct, the ECU isn't sending the ground signal to the clutch and I...
I Need a few ideas now if you can guys and girls, I have an 170 SLK230 which I just bought and it's very under powered. It has 12V to the clutch but no switched ground from the ECU, K40 checked out good and the MOSFET didn't fix it.
Tonight I have put 12V into the clutch connector and it...
I have a 98 SLK 230 (170) and need to read out fault codes. It doesn't have an OBD socket but does have the 38 pin connector in the engine bay. I got an adaptor today and connected this to a Maxiscan code reader which I normally use and it can't talk, any ideas?
:) Well thanks, I would normally knock up a guide but I'm not seeing a happy ending to this one. If I do reach a conclusion then I'll certainly pop it all together - thanks for the welcome!
Thanks, it was a bit of an impulse buy but I'm quite liking it. Sadly the transistor didn't come in the post so no more fixing today but I can spend some time on the other you (grinnal Scorpion) instead
So tonight's update - I figured the K40 wasn't responsible because I have the +12V at the supercharger clutch but I decided to whip it out anyway and resolder it. Looks brand new so I guess has been replaced.
Whilst I was there I checked the ECU fan and it wasn't working, popped it out and put...
OK after a bit of searching it sounds like I need to pull the K40 module and resolder it or potentially the ECU has a dodgy FET (BUK101 50DL), on we plod ...
Hi all,
I haven't been around here for quite a while but just got a new toy tonight, it's a 98 SLK 230 (170) and is in much better shape than I was expecting, no rust on any arches and pretty reasonable all round. It was way too slow though so I just had a quick look in the dark and found a 2...
