I'd be inclined to get it on diags, and check engine and gearbox for codes, and check the kickdown switch is working reliably.

Out of interest how would one go about such a task, TB?
Live data

That only available on TechII?

Pretty certain its in the TCM, so anything capable of reading live data in there :y

thanks for your replies people. The cam sensor was from a main dealer costing £85. Before this Omega I had the earlier model on a T plate, that one did have a physical kick down switch under the pedal where as this one just has a pedal stopper, its all electronic so that idea's out the window. An earlier post suggests the new clean oil is the problem as the old oil would of had metal filings in making the oil thicker. It all goes through the filter and what isn't caught there would be caught by the sump magnet right?- so not so sure on that one.

As far as I know, ALL auto boxes have a mechanical kick down switch  :-\
That would be my first place to look  :)

Drive By Wire cars don't have a kickdown switch (that I can find). I believe the engine load signal from the CAN bus is used instead. Would be worth checking both the engine and gearbox ECUs for codes and, failing that, live data, to ensure 100% engine load is being reported at full throttle.

There may be a kickdown flag in the live data on the autobox ECU - I can't remember. It's not triggered by a physical switch that I can see, though.

TPS perhaps :-\ on mine, kickdown seems to be just past what feels like full throttle...

It does lift its skirt up and get a wriggle on cleanly when asked though 8) (I had promised not to say, but a fellow 3.2ist seemed quite impressed all in all... just don't tell Tunnie ;D)
