Had the ECU read and it says vehicle speed sensor implausible signal, Speed sensor ordered and no problems.........until today!!! On way to work ECU light comes on, Car starts spluttering and surging, Speedo dies etc etc etc, Fault codes re read and now i have the speed sensor fault back plus something about the turbo in relation to the throttle position saying i should check "DV" whatever that is?.

Also apparently i have odd voltages on the coil packs on cylinders 3 and 4 at idle, They seem ok under an open throttle. The car was terrible pulling away wanting to stall in 1st and 2nd, After the ECU read and reset it is perfect again?.

Any suggestions guys would be much appreciated, I have never had so much trouble with a car in a short space of time and am rapidly losing faith in the car.:confused:

Can you remember what the code numbers were?

No mate i didnt get a print out this time:rolleyes:

plus something about the turbo in relation to the throttle position saying i should check "DV" whatever that is?.

sounds like the good old 17705 fault code

This should give you somewhere to start:
