Doesnt amaze me   

Oh....and when you replace that sensor, dont try and saeve a few quid with a pattern / aftermarket one. Get Genuine from Vauxhall. 

Before you go buying a new cam sensor, just try unplugging it and cleaning the contacts with a bit of contact cleaning spray.  You have the same symptoms and codes I had and simply disconnecting the cam sensor and reconnecting it cleared the problem.  I was getting a P0340 every other day or so but I haven't had one for nearly two weeks now.

some gearbox programs run in 'keep it in low gear mode' for a minute or 2 to heat the atf faster, could it be that you are experiencing?

the upgrade is normally a massive improvement.

The car may also take a day or 2 to learn new values depending on what else they have done.
