So my A4 is hitting a brick wall at the following revs
In neutral 4,000 (might be normal)
In 3rd 3,500
In 4th 3,000
It just stops pulling and up to that point it pulls hard. I tried tricking it by hitting the 3k limit in fourth then dropping into 3rd this threw the car into limp mode and the glow plug symbol appeared, once switching the car off and on again the symbol disappeared and I'm able to drive the car in the new norm.
SO FAR
Both heads have been cleared of crap(off the car)
EGR system all cleaned up as well as inlet manifolds and swirl flaps, the actuators perform as expected.
Turbo has been cleaned and checked over with new bearings and a new actuator plus I forget the name of it but the part internally that connects to the lower arm from the actuator needed replaced so that's been done.
Injectors are all refurbed and there's no smoke at all from the car
I have tried another MAF no joy.
And did a quick scan but with the battery being disconnected for another job it throws up a bunch of low to intermittent signals etc, so cleared everything and no faults so tomorrow I can try again.
IDEAS???
I know the DFP could be clogged up
N75 valve
Cam sensor
Boost solenoid
And I'll check all the boost pipes to make sure there all tightened up but like I said the car is perfect up to 3,000 revs
I'll also try running with the MAF disconnected
Is there anything else that could be the culprit?
