Nanocom error

I've had driver demand issues from:
Over boosting, but when it it doesn't register an overboost error this happens sometimes if it is just on the borderline, 1.35 bar is borderline get it back to 1.3.
Faulty fuel pump as sierrafery describes.
Wet or clogged air filter.

The crank angle sensor is found on top of the bell housing just to the drivers side. I wouldn't imagine changing the head would have effected this, but it might be worth checking the connector to it.

Righto, this morning I wound the actuating rod back to 13 threads which is about the original position.

With Nanocom connected went for a drive, turbo pressures still rise to 1.4 bar then zero on Nanocom.

Wound back two more turns, now 15 threads showing, still goes to 1.4 then zero but there is no change to the performance of the car now.

Crank sensor problem once cleared has not shown up again.

I still get the 'DRIVER DEMAND ERROR 1' but no drive problem, I'm at a loss as to what was happening.

Bought a can of 'contact cleaner' I'll start with that.

The only thing that has happened is the car sat in the weather for about 6 weeks while I was getting the head gasket job done.

Someone has fed the Gremlins!

It's classic sign of overboost and the fact that you went back so much on the wastegate rod without effect means that the valve doesnt actuate which can be caused by faulty modulator, boost loss before the valve due to pipework or shot valve... connect the thin pipe which comes from the intercooler to the bottom of the modulator directly to the valve and if it's still the same it means the valve is stuck but if this way is OK the modulator is gone ... can you move the rod forward with a pliers?

Use this info , if pipework, is good and bypassed modulator doesn't fix it then its the actuator or wastegate

Thanks guys,[bigsmile]

Sometimes you can't see the trees for the forest![bigwhistle]

I didn't put the retaining clip on the pressure hose from the turbo to intercooler pipe so it blew off, my blue!!!![bigwhistle]

I probably wouldn't have looked there but for your advice, thanks again.[biggrin]
