Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

have a M-Reg Gsi Corsa (X16XE)

And have problems with the engine not revving up,

So far ive changed:

- Idle Control Valve,
- Throttle position sensor
- Crank sensor
- Cam sensor
- Map sensor
- Egr valve (second hand but good condition)

Have had the Inlet manifold de-coked and cleaned out so is in A1 condition, re-fitted with new gaskets..

Just had a Snap-on Solus Diagnostic Machine pluged in and its come up with the following fault code:

"Quad drive module"

would this cause the issue im having?

Any help on this matter would be much appriciated...
