Hi , i have golf 2003 .Someone connected my car battery on the wrong way would this blow the computer? or it is just a burned fuse ???

 

Welcome to the forum.

Yes it could do but it will damage the alternator first.

So who connected the battery up wrong an ex friend?

Doesn't the car start now?

 

yes it doesnt start now i checked the fuse box one of them was not working and it is burned and i am wondering what would happen now !! ((

 

So it doesn't start at all or it starts and runs for a second the stops that is the immobilizer working which can be another pain in the a**e to remove?

So you've checked all fuses and connections. The 109 relay in the fuse\relay box under the bonnet does go faulty so its worth carrying a spare in the car just in case when you do get it running.

 

thank you man it is solved now and the car is working fine (it was wiring problem)... Now i have another problem ::

WV golf check engine light just came in i checked the codes i got after computer scanning , i got 7 codes all of them related to the gear (Wiring/Connectors from/to Solenoid Valve 2 (N89) Open or Short to Ground)....

Well i was shocked and surprised since the car is working well and i cant feel anything wrong with my gear transmission.

So i told the guy who did the scanning that i changed the gear before 4 months and i just have changed the battery today.

he said so it is normal since they are a new ratios to the computer not the original and the car is safe.

shall i blv him and forget this stupid light ? and is there any way to turn it off ?? my car is golf 2003
