my money is still on crank sensor or the cam sensor!

I cant tell you how unpleasant things will get for the garage and the dealership if turns out not to be the ECU. As I said its been 5 weeks so far, and the dealership wanted £1200 for a new ECU, which the vauxhall master technician insisted was the fault.

The cam sensor is about the only known weak bit on the 2.2, fairly bullet proof engines.

Do you know if genuine sensors were fitted? I am thinking they may have fitted a 2.0 cam sensor or something daft

According the garage they were genuine, but anything's possible, at the moment I am pinning my hopes that the garage and the dealership  are correct and the new epu resolves the problem. If it does'nt then its back to square one.

Mark, do you have the security code for the immobiliser?

For the above codes, TIS recommends a full re-program and rest.

yes mark i think so should have the car pass somewere  :y

Is this something I should be conserned about?

Well, they fitted it, and the car still will not start, will turn over but not fire up. They tried the new throttle body, made no difference.
 We are now exactly were we were 5 weeks ago. I am furious. Not so much with the garage but at the dealership who wanted £1200 for the new ECU that was "definatly "the fault >:(

The codes we are getting now are -
P0120 Throttle Position Sensor
P1120 Pedal Position
P1550 Gen Electronic Throttle

Any help on this would be greatly appriciated.

LOL, "defo ecu fault" - sounds like most dealers!

We need more info.  Are these fault codes current, or stored.

Also, do a live data, and see if pedal position and throttle position match over a range of positions.

I'm assuming that the EML works, and that its not flashing.

OK, sorry, I don't know if the faults are current or stored, how can I tell the diference?

How do I do a live data test, or more importantly, how do I tell the mechanic how do a live data test.

I'm sure it is, but I'll check with the garage this morning.

 Its quite a humbling experiance not having a clue what is going on, and I am extremly grateful for the help, advice and indeed parts that I have recieved from this site, I am acutely aware that I can offer little back in reconpense, my trade is data analysis and IT data exchange systems, not something you need on a daily basis, however if anyone needs any advice or help with MS Excel then look no further

Their code reader should say if its a current or stored fault.  As to live data, it depends on the capability of their code reader.

Why am I not in the least bit surprised that it didn't fix it!

Because, unlike garages and most dealers, you have half an ounce of common sense to diagnose before spending your customer's money on the offchance it may fix it.
