I have had a 320D Auto from new, now done 65K miles.
It had a new Turbo at 48K and last year I had the EGR replaced which transformed the performance.
However, this car still belches out smoke, best described as dirty white, under hard acceleration and that's after a period of local crawl or several hundred miles of faster driving. It makes no odds. Last night I was flashed several times on the M25 by following cars engulfed in smoke. It burns no oil at all.
The private mechanic I use can find no faults. Exasperated I paid a BMW dealer for full diagnostics and they could find nothing wrong either.
I am flummoxed. Would a Remap help? I am thinking the fuelling is wrong, or alternatively would increased turbo pressure help?
All thoughts are welcome as I cannot sell it yet am increasingly reluctant to trust using it.
