A6 2.5 TDI AFB 00575 Inlet manifold pressure exceeded.
Symptoms include intermetent loss of power, ranging from total loss & having to cruise to a stop on the hard shoulder to partial loss i.e. wont rev beyond 3k & then gradually falls off.
Particularly bad first thing in the morning (within first 1/2 mile of my journey) or when accelerating hard to overtake or get up to speed on motorway slip road.
The above code if cleared, will return after the first loss of power incident.
I've checked all vac hoses & they seem to be OK.
It doesn't smoke.
VGT actuator seemed to operate fully & smoothly last night when & sypathetic Audi tech ran a test with his gadgetry (does this also confirm N75 performance?)
Also during test with same gadgetry boost was found to be operating within acceptable parameters.
MAF was fine at tickover but showed a shortfall when on throttle.
Any pointers would be gratefully recieved.
