I read a lot of posts regarding the supercharger issue but i can't find a proper guide to resting the solenoid position on mine so a pointer would be helpful. It's very intermittent and it's not my main concern atm as I have BAS and ESP lights on not to mention SRS.

Car is an 01 w203 c200K with 970230 miles on the clock engine is M111 i think.

anyway I'm getting a yaw sensor fault C1120 and yaw sensor live data shows 88deg which bumps up to over a 100 deg and back down when the car is at a stand still, found some corrosion on sensor points and connector cleaned it worked for about a minute and then fault was back, i m guessing faulty sensor.(first 2 pics) i m also having a C1210 ROAD TEST fault which i managed to remove but it gets back on when the yaw sensor fault shows

other issue is I'm not sure if it is a fault as i don t have any BAS faults when i attach the diagnostic however when playing around with the tests i noticed that the stop lamp switch has an NC and NO points i m assuming normally open and normally closed, however one of them keeps it s value constant with pedal pressed or not (3rd and 4th images). Is this normal or do i have a faulty brake light switch aswell?

I m using Icarsoft MBII to read codes.


Thanks in advance,
Dani.
