My 2007 Lexus IS 220D is smoking, the car has done 130k and i've owned it for around a month. No warning lights are on and there's no smoking while stationary i.e when i rev the car when it's parked up.... i only do short journeys, to and from work which is 2 junctions on the M60 then too and fro from the shops , running the kids to school and so on....I've been reading a few post's on the forum and i'm thinking it could require the EGR valve to be cleaned as i've no idea if this has ever been done and as stated it's got 130k on the clock, also could the short journeys be a factor??? Any help or info would be appreciated.
