    W221 Front Parking Sensor Replacement

    Hello! My parking sensors have started to stop working intermittently. I am getting the following error when scanning using iCarSoft MB II: - 9009 B8/3 (Inner left front PTS ultrasonic sensor): Sensor is faulty. Current and stored. According to some youtube video comments, a lot of people have...

    P0237 om642

    Hello, I would start by checking if there are any air/boost leaks and also check if the turbo actuator is moving freely. Let us know how you get on.

    W221 S320 CDI - P1101 MAF Diagnosis

    I'm sorry, I don't exactly know what P1101/2646-000 means as I scanned it using iCarsoft MB II and it gives me those codes but it says not found in database so it doesn't explain what they are. That's why I thought someone here might know what they mean for a Mercedes. It gives P1101 when using...

    P1101 Fault Code - 320CDI - Any Ideas Please?

    I have the exact same issue, posted my own thread on forum a few weeks ago but doesn't seem like anyone else has come across this. Did you ever fix the issue? Thank you.

    W221 S320 CDI - P1101 MAF Diagnosis

    Thank you for the support. I noticed that although fault 2646 is stuck on permanent even after clearing with engine off, I am also getting the following two error codes when I intermittently have acceleration problems: - 2592 - Position sensor turbo actuator - 2696 - Left exhaust pressure...

    W221 S320 CDI - P1101 MAF Diagnosis

    Hi all, thanks for the replies. Here's the update: - I cleaned both MAFs but it has made no difference. - When unplugging right MAF, P1101 is still there but I now have P1100 and P1111 as well. With MB ECM scan this comes up as 2646, 2602 and 3052. - When unplugging left MAF, P1101 is still...

    W221 S320 CDI - P1101 MAF Diagnosis

    Hi all, I'm getting P1101 error which I believe indicates a faulty MAF. The error code is current and immediately comes back with ignition on, engine off. The OM642 has two MAFs which I understand cannot be replaced individually as they're welded onto the 'bat-wing' intake manifold. Thought I...

    W221 Airmatic Suspension Noise

    Yes, thank you. I will only consider the PRV swap option if my warranty claim is unsuccessful, fingers crossed!

    W221 Airmatic Suspension Noise

    Good to know - I'll definitely consider that if I don't get anywhere with warranty. I'll also have a look to see if I still kept my original unit and try swapping over the pressure relief valve.

    W221 Airmatic Suspension Noise

    Thanks phobos, looks like it's installed properly then. I had hoped this was supposed to be connected somewhere to muffle the sound when the compressor discharges back through the filter. I purchased the compressor through EuroCarParts, it's labelled as being an Anschler unit so I guess not...

    W221 Airmatic Suspension Noise

    I noticed that the hose connected to the air filter isn't connected to anything on the other side but is supported by a rubber square "bracket" - is this hose supposed to be plugged into anything?

    W221 Airmatic Suspension Noise

    Hi, just following up on this as I’ve had a chance to take a closer look at the compressor. Still making the loud pressure release sound every 30 seconds while driving but still no warning signs and car stays level. I’ve checked the inlet pipes/filter and all look fine. I removed the pressure...

    W221 Airmatic Suspension Noise

    Is it normal to dump pressure through the inlet filter? Prior to this happening, the car would give more of a "whoosh" noise from the compressor area when I unlock the car in the morning and then again once or twice when I reach my destination and lock the car - I understood this was normal. But...

    W221 Airmatic Suspension Noise

    Morning all, have a 2007 W221 LWB S320 CDI. It had a compressor issue a year ago with the suspension fault light on the dash and found the car dropped to the floor. The compressor was changed and car had been working problem free since. However, a few weeks ago the front right side begun to let...

    W221 2007 Air Suspension Dropped

    Hi all, I have a W221 2007 S320L CDI. Air suspension has dropped on three corners (both rears and drivers side front) but the passenger side front is still raised. Starting the car I can hear the compressor running but the car doesn't rise at all. Unfortunately can't move the car as it was...

    OM642 Misfire and White Smoke

    Thanks for your input. I will do a leak off test and then change injectors 3&5. I will update you guys. The live data above was after the Mercedes specialist timed the fuel pump to cylinder 1 TDC. It now starts immediately instead of cranking for 5-10 seconds but still idles really poorly and...

    OM642 Misfire and White Smoke

    Any advice would be appreciated. W221 S320 CDI OM642. Only 60k miles. Car was working fine then started misfiring with white exhaust smoke unburnt diesel after removing and refitting high pressure diesel pump as it was leaking, inside screws were loose. I have tried fitting a spare pump and no...

    W221 S320 CDI Engine vibration won't rev

    Aha, I found this picture. I guess this is what I should be aiming to see. Quick question if anyone knows - if I line this up will I definitely be at TDC or could I be 180 degrees out?

    W221 S320 CDI Engine vibration won't rev

    Right...I had a quick look this morning. I found the crankshaft sprocket with the TDC indent at 12oclock. However, I can’t see where the indent is on the pulley to know how far to rotate. I see an arrow with the number 2 on the pulley as shown- is this what should face up?

    W221 S320 CDI Engine vibration won't rev

    Just been doing some more reading and found a PDF which says when installing the high pressure fuel pump, position piston of cylinder 1 on crankshaft to ignition TDC. Maybe OM642 does need the fuel pump timed correctly :wallbash: I think my timing is wrong and the white smoke is unburnt fuel! If...
