I have a 57 plate is220d with 114000 miles on the clock....
A few weeks ago I noticed an awful cloud off blue smoke coming out of the exhaust under acceleration, as soon as i lifted off the accelerator it cleared immediately, when i put my foot down again nothing, no smoke at all. Now i have noticed this issue a few times, but mainly it was after hard accelerating after either sitting at traffic lights or stuck behind very slow moving traffic (30mph for example)
But on Sunday me and a few mates where away and driving along at 70 mph with cruise control on started going up a hill and the elusive blue smoke again.... so much so my mate following behind phoned me to alert me. It doesn't do it every time, mostly within 5 miles of first starting the car. but on Sunday this was the first time it happened after a 60 mile trip.
I have removed the egr valve and it was still clean from the last time.
a friend run a full diagnostic check and there are no faults showing what so ever.
inspected the turbo and there is no play, or rub marks inside it.
and i am assuming the dpf filter should be clean, i know supposed to clear itself after a long run. 4 months ago i drive from N Ireland to Germany and its was a very speedy run on the continent i don't the the speedo was under 100 for over 2 hours so that should of regenerated it.
I am a complete loss so before i book it into Lexus and pay them vast amounts off money to maybe tell me what wrong can anyone out there help me?
