Rough idle 1.2 azq 3 cylinder

Not to hand at the minute but I'll post them on here tomorrow. I just can't understand it because I've changed just about everything that could be at fault really and getting close to giving up

[domleadenham]

Am I correct in thinking the angle sensors are on the pedal and throttle body crasher?

[Crasher]

The one that is showing the error you have is the throttle body, both the pedal and throttle body have dual opposite swing potentiometers. I had this fault on a Lupo 1 litre a few years ago and it was the ECU. It is rare for an ECU to fail but it does happen. One of the fault codes you posted on the other thread is very specifically and unambiguously a faulty ECU.

[domleadenham]

I've tried a different ecu and it was still showing the same symptoms. I'm thinking the wiring has got to be at fault

[domleadenham]

I've also changed the pedal Ms throttle body

[Crasher]

Did you run it with the new ECU after coding it in and adapting it to the immobiliser with it then showing the same fault codes?

[domleadenham]

Yeah still got the same problem. I changed the ecu, ignition chip so the ecu so it would recognise it and the clocks so I wouldn't have to recode the ecu. It did come up with the ecu fault before and after the ecu change but that fault has now gone (original ecu is back on so the mileage was correct). I plug the vcds back in and get the codes on here for you to have a browse and see what you think. I can't think what it can be because like I said I've changed just about everything. It only happens once it's up to temperature 90'c. Could it be that the chain is attached and when the car is up to temperature the chain is stretching causing the fault? Unlikely I know but I can't think of anything else

[Crasher]

You could do with checking the valve timing.

[domleadenham]

Is there measuring block on vcds to check or is it a case of rocker cover off?
