[Audi A3/S3] Audi a3 ABS light and air bag light

Hi I wonder if someone could help me.

My Audi A3 has been tucked away in a garage for 3 years on a SORN, prior to this there were no faults. Now as i want to get it back on the road the ABS light stays on, which i'm told is an MOt failure. Could this be a quick fix? As i mentioned it had no faults previously.

The airbag light I am not so worried about as I am also told this is not an MOT failure.

Thanks

A vagcom scan would tell you.

- Airbag light is probably the connector under one or both of the front seats - Yellow connector i think. Take it apart and spray with electrical cleaner.

- ABS light could be a failed brake light switch on the pedal. Simple to replace for less than £10. These are common parts to fail, otherwise maybe Yaw sensor or something else.

My airbag light has been on since someone slammed the passenger seat back into place, I have disconnected/cleaned/reconnected the connector underneath (similar happened when it was new) but the light stays on. Does it need to be switched off by a dealer/Vagcom?

It switches itself off when you have sorted the fault.

It took me a few tries on my A4 to solve this problem and ended up using switch grease/lubricant on the contacts. They sell it for radio controlled cars so most hobby shops sell it. Prob exists in other forms too.

A VAGCOM scan would tell you for definite that it is that connector.
