Thread: fault that keeps popping up

The driver demand circuits are for the throttle position sensor. I've only recently got my TD5 back on the road after replacing the section of the loom between the black ECU plug and the throttle position sensor (6 wires in total). My fault was "Driver demand 1 out of range" though and it would make the ECU cut the engine to idle with no throttle response.

I eventualy got a diagnosis using my hawkeye to watch the driver demand voltage and wiggling the loom where it exits the seatbox.

After I repaired that I could only get about 65mph out of her which turned out to be a stuck waste gate. I think I got an error for something loke overboost and one for manifold pressure iirc.

Wastegate is easy to check, get a hold of the rod coming from the actuator with a pair of mole grips. You should be able to (with a little effort) move it towards the turbo body. Mine was solid. In my case it was the wastegate itself that was siezed rather than the actuator. a little bit of WD40 and a wiggle with some pliers sorted that out. She now pulls like a train right through the rev range.

If it assists at all....

3 = Driver demand problem one logged
0 = Generic
28 = Injector peak charge short

If the 28 is followed by numbers up to 5 eg - 28-1 then that is the relevant injector...

This is straight out of my Nanocom manual

Yea ur right the wastegate is stuck does anyone know how to unstick it. And should there be oil in my intake system or is my turbo on the way out my car is coming up to 100000km how long do they last.

Turbo should last at the very least around 300,000km if looked after by cooling after long runs and the like.

In my experience turbo's don't give much warning when they're on the way out. I lost one on a 300Tdi due to an unrelated oil pressure issue and it went from ok to "disintergrated" in a distance of 2km.
