Hi all
After some advise, a friend of mine has a 2008 1 series coupe n47 177bhp. When driving under acceleration is seems to almost stop boosting, and just bellows out smoke. At first we thought it may have been the MAF or a boost leak of some sort, but when we changed it and searched for a leak it made no difference. We then tried the egr which was surprisingly clean. Which led us to the DPF.
After removal of the DPF it became clear that someone had "gutted" it. Could it be that the previous remap has somehow failed and reverted back to OEM settings, which is constantly trying to force re-gen? This is the only sense I can make of it by the amount of smoke it outputs which is accompanied with a lack of power and eml.
Fault codes as follows
3F01

any advise would be appreciated
TIA
