alarm not working

saldly didnt notice most of this when brought from private seller (schoolboy error i know) had a chat over the phone with the guy and he said the battery was disconnected at some point and this could have caused the problem !!!! would reseting the ECU fix or do i need to get it to a specialist, i have checked the fuses no probs there ???????

many thanks for reading

 

Airbag, central locking, and alarm can probably be reset using a VAG-COM. Radio will require the radio security code, which should be located on a card in the operating instructions manual for the radio itself, otherwise your local dealsership can look it up for you using the serial number.

 

When you scan with vagcom, note what the airbag fault is. Chances are it's the driver's side bag (not the steering wheel - the side airbag). Look under the front of the seat - you'll see a yellow connector. That gets strained sometimes when the seat is moved all the way back and it disconnects just enough to trigger the light. Zip-tie it tightly (be careful of the wires so you don't pinch them) and then reset the light and it should stay off.
