Hi all, new to the forum and have not long owned my A3 having bought it around 2 weeks ago.
She's a 170 2.0 tdi sport with DPF (sadly) and used to pull like a train, now not so much.
I'm sure its loss of power and not just me getting used to the pull as when accelertaing when reaching around 3k rpm in 3rd the boost cuts out for a few seconds and then suddenly kicks back in.
It does this in most gears and there is a noticeable on/off feel to boost when approaching 2k rpm also
The car sort of judders due to the loss of power and feels noticeably slower, it still goes but its definitely not the power I had when I first purchased!
Car is booked for a full service tomorrow, hoping this may help!
I removed the blanking/restricting plate from the air box the other day which seemed to improve the feel/power somewhat. It's almost as if I have a loss of pressure from somewhere.
Any ideas on what to check? I did presume it could be the DPF becoming clogged but I commute to work so would presume this would be in working order (20 minutes each way, 70 mph all the way)
Thanks in advance guys
EDIT:
From time to time I notice that when I pull up, the car will idle at around 1k rpm and the exhaust sounds lumpy but after around 3-5 minutes the car returns to normal rpm. Correct me if i'm wrong but this might be DPF regen or the alternator running higher to compensate lost charge?
