Hi, I have a 2005 E350 CDI W211 with around 140K on the clock. The car generally drives fine but I've had an ongoing issue with the car putting out white smoke after a long idle or drive in slow moving stop/start traffic. Once the car is driven hard the smoke quickly disappears, only to come...

Hi Gokdag, Sadly the problem is not fully resolved. I took the turbo off and had it rebuilt and also replaced the inlet shutoff motor (the shutoff motor had failed and I don't think was related to the smoking problem). I'd also taken off the EGR pipe that comes up from the bottom/front of the...

Hi, Can anyone recommend a good turbo specialist who'll recondition an OM642 turbo? I have a W211 E320 CDI, the engine had gone into limp mode and was reporting a fault with the inlet shutoff motor. Before the fault it used to smoked heavily, after a long idle, and I noticed the end of one of...

Hello, I have a 2005 w211 estate with 130K miles. I've been experiencing a whole rage of problems which, I believe, are related to the turbo and inlet shutoff motor. Apart from this the car runs well and I really want to resolve the whole problem rather than part of it. Here are the main...

Thanks for the info Black C55 - I wondered if it was a turbo issue - the car occasionally stutters under hard acceleration which I understand is caused by a problem with an actuator on the turbo. I've also just found our the car is reporting a fault: P2A00 which is an upstream O2 sensor. Am I...

Mostly white with a bit of blue....

Hi, I have a W211 E320 CDI which has just failed it's MOT on emissions. The car passed the smoke test with a reading of 0.02 when the limit was 1.50 but the tester said it had failed due to the excessive visible amount of smoke and stopped the test at that point. I was unaware the car was...

Hello, The transmission on my E320 CDI has started making a slight groaning/humming noise when in park and neutral. The problem is only noticeable when the car is cold and only in park and neutral. The gear change at low RPM is also a little clunky when cold. The car has 130K miles and a full...

Hi, Thanks for you advice on this - I got another STAR test done today and it came up with 2 fault codes: 2668 - Check component G3/2 (O2 sensor upstream of TWC). Thrust fault value is below limit. 2270 - N14/3 (Glow time output stage), At least one of the glow plugs in not actuated Does the...

I have an E320 sport with 120K on the clock and a white smoke problem. When the car is started it can sometimes take a while to start (5-6 seconds) and when it starts a puff of white smoke is emitted. If I turn the ignition onto position 3 for 10 seconds prior to start the engine starts...

Thanks for your advice on this - it turns out water had got into the enclosure containing the ECU - I dried it out with a fan heater and all works fine now.

Thanks for the advice, I'll do as you suggest.

Hello, I have a 1995 E320 sport with an odd problem. The car has been working fine but last night the engine cooling fan started running for no reason - the car was parked, locked and hadn't been driven for 3-4 hours and the fan was running at full pelt. I unlocked the car and the fan...
