Nonsense.

Replace the Cam Sensor with a genuine one from a Vauxhall Dealer you genuinely have to walk into.

And report back.

On that engine, those codes have absolutely nothing to do with the gearbox or its ecu.  ;)

So doctor your saying those codes are cam sensor to be clear 👍

Exactly  :y

That's to say the codes suggest imminent gearbox death.

The actual cause is a failing cam sensor.  ;)

Good luck with the replacement, I found it to be a complete pig on my 2.2, one of the most awkward jobs I've ever done.

Ahh, I meant the crankshaft position sensor   :-[. The cam sensor is not so bad.  ;D

I presume all the vacuum and wiring connectors that were undone for the cam cover change have been double-checked, could just be an air leak.

p.s. I'm not an expert on 2.2s by any means
