I suspect mine has an issue (well, I know it definitely has something going on) and symptoms are pointing towards overfueling, i.e. possible injector.

AFAIK not as much as the N53, though I had to have my coil-packs (330i 2005) replaced recently to cure a mis-fire. Soon after had to replace the pre-Cat 02 sensor too when mis-fire returned, so possible that it was that all along.
Next job to sort - leaking oil filter gasket housing! Any other N52 owners have this? (slow oil leak making a mess of the front / off-side of the engine block) Seems to be quite a common issue - not serious but fiddly to fix and looks messy under the bonnet...
