Greetings fellow Mercedes-Benz Owners, I bought a lovely W203 C270 CDI a few months ago and I've had loads of happy motoring with it. However when I initially bought the car, I had to replace the boost solenoid since the present one was causing limp mode. When I ordered a new one, it arrived...

Hello. I have a w210 e320cdi which gives me a headache. I checked the cables(they were fine), and change the MAF sensor but i still got some kind of a weird reading. At idle i got around 300 mg/hg (i don't remember the unit correctly) and when i'm at around 1500rpm i got around 400 mg/hg BUT...

So I got an engine management light, went to merc and they quoted me £3k in repairs for a blocked air manifold, stuck exhaust flap and a suggested EGR replacement. After some independent advice I tried some fuel system cleaner £40 and the light as gone, however I have bought a OBD reader and...

Hi! My car recently failed a emissions test because of too high CO. The car seems to be running rich too. I have not noticed the car running worse/rough or smell from exhaust but fuel consumption feels exsessive. The car is throwing the following DTC codes: P0170, P0137, P0172, P0138, P0136...

Hi. I need help again. I have a C230 1998 (W202). We had a problem with MAF sensor and changed it. After 10 days it broke down again. I thought it was defective and changed again, it also broke down after a few days. We changed it again, it also broke down after 2 days. I don't know what to do...

OK. Firstly I apologise for the long winded nature of my post. I have a 2010 CLS Grand Edition with 108k miles on it. A few weeks back I was driving normally at around 30mph. I stopped at a junction. Accelerated quite quickly into the road and I felt a strange vibration in the throttle pedal...

Hello, Is it ok to clean MAF sensor by flushing it with alcohol? Thank you, Arv.

Strange issue with my CLK today. Headed off to work and car started fine, then 2 minutes up the road, I remembered that I'd forgotten something so headed back home. Pulled up outside and ran in the house to grab what I needed (was in the house all of 2 minutes) and then came back out, jumped in...

Hi everyone, Haven't posted for quite a while, but thought I'd share this experience since it has reached conclusion. The full story is in the reference given, but in essence, a faulty MAF on my car was causing a pending P0221 and disengaging the accelerator. I know the MAF was fine...

I've seen a few post on here with the same issue as my car but no definitive answer Today my W203 C220 CDI stopped reving past 3000RPM I was told one possible cause is the MAF sensor I disconnected this while the car was running and there was no difference at all. on my last car (A Nissan...
