[Pyro]

as above got these fault codes and cars running **** i recently took the inlet manni of and polished i cant find where i might of missed an earth of a wire could be touching any help would be great

the only bolts missing are

1) the bolt the bolts into the head bolting the carbon canister pipe down (top left of the head tight at the back)

2) the bolt that goes underneathe the manni on the TB side to the right of the little tray theat goes through onto the big black bracket.

I had this all i did was take my earth strap off and make where it straps to the body shiny again then it was fine

 

[Pyro]

The main earth strap to the battery? I'll give that a go tomoz did you get the same codes?

 

[yellonvi-R]

Yep more or less the same codes mate all of them where either short to ground or signal too low! So yeah i just took my battery off charged it up a little then made the earth to the body nice and clean and shiny again. All i was left with after was my n249 fault hence bypass its worth a try as it dont take long lol i had around 12 codes before i did it!(

 

[Pyro]

will try it today mate cheers

 

[Pyro]

anyone else got any ideas?

 

[yellonvi-R]
