some codes there mate but checking through them P1746/01119/17978 are bogus codes so forget those as for the rest lets take it in stages and the first issue is a lose/over tight/ poor wiring connection knock sensor which could in theory throw all the other codes so check that first

 

Thank's Avant
your a legend, I will check them tommorrow and I have elminated the codes you said.
Thanks Addam

 

just found 17978 / P1570 engine control module (ECM) immobiliser active, possible cause incorrect/damaged key, incorrectly coded, ECM/immobiliser replacement without coding, wiring, immobiliser defective.

now if you cant start the car this is your problem

 

She starts first time every time.

Hey Avant
My key is a bit bent would that cause that problem
addam

 

nop not the key then if it starts that was only one of the possibles so now eliminated, do the first check (clear the codes and see what comes back) if none then it could have been old stored codes where someone didn't clear them.

just to cheer you up I don't think its a big if any problem as long as the CEL isn't on, codes can confuse people when you get so many and the more is better because its generally something simple which causes all the other codes and in many cases its down to the fact the codes were not cleared on a previous occasion

 

Thank's Mate
Also I must commend you on how you are alway's there to help, Don't forget if you ever get to the Gold Coast of Australia let me know. I owe you now 2 beer's Ha Ha

Well, I'm coming in a bit late.

I'd clear them all, and see what comes back in a week. God knows how long those codes may have been stored, and none are critical.

I have my own vagcom and scan about once a month to catch is new codes are appearing.

 

Thanks David9999, you just want a beer as well don't ya !
