TT TFSI EML CODES
Hi all, wondering if i could try to get a more accurate idea of what i'm dealing with in these codes on my TT 2007 2.0 TFSI BWA:-
08583 bank 1system too lean at idle P2187 no signal/no communication
08801 boost pressure control valve (N249) mechanical malfunction P2261 not a plausible signal
So car starts, idles & drives perfectly well with no obvious issues. I cleared faults initially & they came back on about 2 days (40 miles) later, not immediately.
Are the 2 codes related, possibly Diverter valve or N75 valve or both or maybe an intake leak. PCV seems ok as taking off oil filler is easy, not sucking & causes uneven running (normal i've heard).
Probably gonna do a smoke test next but any help would be greatly appreciated.
