Hey, I'm looking for some technical help with a 2006 A3 2.0 TDI (BKD engine 140bhp with 75K). For a month or so i had problems at motorway speeds (80 mph+) of the car entering limp mode. Sometimes it gave a fault code, sometimes it didn't. It was however P0234 (overboost). I put this down to a possible carbon build up on the turbine vanes (apparantly a common issue). The turbo eventually packed in (main bearing) and i'm now enjoying a recon turbo. Problem is, it has still got the limp mode issue at higher speeds as before-giving the same fault code-overboost. I have an OBDII reader and the last fault gave me the following freeze frame data:
LOAD_PCT (%) 71.4
ETC (F) 198
MAP (inHg) 69.4
RPM (/min) 3119
VSS (mph) 85
MAF (lb/min) 15.050
TP (%) 94.9
Is there anything in the above that could point me in the direction of finding what the problem is?
Alternatively has anyone experienced this and what are the possible problems?
Thanks in advance, I hope i've given enough info
