Hi,so hopefully someone can help me on this..
I have 2006 W211 2.2 cdi (125kw) auto.Facelift
Its winter here now and temperatures are around minus 10 to minus 15 celcius in the morning.So when i start the car alot of blue smoke is coming out for around 5-10 mins until it gets warm.Also its smelly(must be diesel)
Also when driving until it gets warm there is a small vibration coming from the engine on 1200 revs.
Had injectors taken out and diagnosed the other day,they are all perfect.
Dont know if its common but my DPF filter gets clogged evry 6-8 weeks and regeneration starts(alot of smoke coming out of mufler) any time unexpected..what i do is i go to motorway on high revs for 30km and its ok for another 6-8 weeks.Thinking of cleaning or removing dpfilter alltogether.
Anyone expierenced something simillar?any thoughts?
Thx

 

Did they put the injectors back in the same cylinder from which they were removed?

Did they test the glow sequence\timing\length of??

 

I suppose they did put it back there they supposed to be,they also reprogrammed them again..
we thought that the smokes were caused by injectors fault so thats why we tested them.
i have prints from diagnostic,so it tested:
DFi(800).,DFi(400).,LKT.,aNOP.,if that makes any sense...all seem to be in the limits..also all of them failed for RSP test but i was told this is not a fail...so..
