Hi there, I've been reading on the forum for years but just making my first post here, thanks for all the advice on many issues, and thanks in advance for anyone who may be able to shed some light on my current predicament!
For a while my van has been going into limp mode (the revs are limited to 3000rpm) it usually will happen after driving for about half an hour and then when accelerating up a hill it will loose power and go into limp mode along with the EML coming on. If I switch the engine off and back on it comes out of limp mode but the EML stays on. Occasionally the EML will be go off again, but then soon enough its back on along with the limp mode.
I finally got round to buying a code reader - there were I think 7 codes present, which I cleared.
I then drove a few miles and checked the codes again before the EML came on, the codes present were -
P0409 - EGR sensor A circuit
P0401 - EGR Flow Insufficient
P1162 - manufacturer control
P0490 - EGR control circuit A high
P1351 - Manufacturer control
Amazingly it has then stayed like this for almost a month without the EML coming on. Then yesterday the EML came on again along with the limp mode. I stopped and checked the codes which were as above but with the additional ones below
P0234 - Turbochager / supercharger overboost condition
P0100 - Mass or volume air flow circuit
So I would guess that this means its the P0234 or the P0100 that is causing the limp mode? Does anyone have any experience of this and where I should start looking in order to fix the issue?
And with regards to the EGR codes, how serious do people think these could be, there seems to be conflicting advice on EGR blanking... If the EGR related codes arn't making the EML come on are they really much of a problem and can I just ignore these ones....?
My van is a 2007 1.6hdi
Many thanks if anyone can share any advice on this.
