You've read it all before.
There's loads on the net about this problem and it never seems easy to diagnose or fix...
Anyone wanna play?..lol
So an old car now..W220 S320CDI '05
Not losing coolant, no noticable leaking at injectors by eye however it had been a bit lumpy on acceleration whilst warming up so i treated it to a bottle of redex fuel cleaner which did seem to help....
2 months later i accelerate hard and it goes into limp mode. After i stop, turn off key and get going again its running fine but i notice some smoke and get hit by EPC visit workshop and engine light on.
Change fuel filter and these warnings go for a few days as does the white smoke..but a bit smoky returns intermittently but not too noticeable and clears once on the move
As im sort of winning i decided to give it an oil change with oil filter and air filter too and clean the egr valve which was only sooty as it turned out..
Boom...epc and engine light back on and now billowing smoke, enough to make me a youtube star by electric car driver with dashcam.lol..and stinks of diesel outside the car...which im hoping proves i didnt put petrol in it..
So i'll be booking a Star session but at the mo im just guessing what it could be...
