Any particular diagram your after ? I've got the complete set, if it's engine related the engine code would be needed 

Not entirely sure!! I've got an intermittent immobiliser issue. My mechanic said it might not be the immobiliser,could be anything. Fault code P1570,key not matched,no power to ECU,ECU not matched,instrument cluster not matched etc etc. I've had cluster and ECU checked,new key cut, 2 new batteries. Now a wiring speacialist is going to look at it. Might be something simple. Car also starts poorly and smokes,smelling of fuel!! 

@Nathan_W When you say 2 new batteries was that key batteries or the main car battery?

 

If the main car battery hasn't been replaced change it - a cream crackered battery throws all sorts of codes such as the ones you mention and would make the car start poorly

I put my mk5 golf battery on first,still intermittent fault,then a brand new battery,also had new key cut and coded. When I put the brand new battery on,I also changed the 1 relay I could see(with fuses in engine bay),car was ok for a week, now it's back to intermittent fault!! The car is fine until the immobiliser symbol and pre-heat symbol are flashing,when that happens,the car starts and then cuts out after less than a second. If the immobiliser symbol and pre-heat symbol stay solid,and then go out(how it should do),the car will reluctantly start!!

I was going to get the immobiliser bypassed,which is quite a bit of cash,with it being a siemens ECU. But the wiring guy I spoke to,seems to think it's maybe a fuelling/spark issue because it's intermittent and the preheat symbol is flashing(as well as the immobiliser symbol). So if I get rid of the immobiliser,I'll probably have starting issues in the near future?? I'm at a bit of a loss with the whole thing!!

They could have just lost their code have you tried coding them to the car?

Yeah had an auto electrician guy look at it with vagcom
