    I had a problem with my passenger side one,
    disconnect the battery, leave 1/2 hour then unplug the connectors under the seat, give the pins and connectors a clean, squirt with WD40 and connect back up.
    you will need to get the light reset though through vag com

    Thank you for your replies, the garage I take it too is a friends and he only has a snap on tool but it's saying its a fault with the offside airbag and when it was at audi last year they said it was that 1 too and would cost £300 plus vat to fix. Is it an easy fix myself as in do the plastic panels just pull off as cannot see any fixings.

    Cheers Jay

    remove airbag plug for that seat
    clean and refit
    then have the code cleared

    if that dont work it could be the wireing under the seat this needs the plug cutting off and rewireing
    then the fault cleared

    if that doesnt work then its new bag time

    There is fix for the wiring loom under the seat that comes out of the carpet, basically the existing loom is too short, get it reset with vcds and see if it comes back

    is it the front side airbag or the rear side airbag
    might be an idea to have a look on the vcds map on here and ask a member if he could possibly scan the car for you to get the exact fault code
    sometimes they will clear easilly , you may have to clean the connector and plug with electrical contact cleaner
    after this replace the plug and connector is this doesnt work
    its either a new airbag or replace the airbag with a suitable sized resistor to simulate the airbag still being in circuit
    this will enable the rest of the airbags to fire in case of an accident but obviously not the faulty one

    Sensor or airbag? The description you've been given is vague - you need to know exactly what the fault is being caused by. Get someone with VCDS to scan your car and note EXACTLY what the code and description is.

    99 times out of 100 it's caused by a bad connection to the side airbag in the seat.

    Thank you for your help, I'm sorry it's a bit vague but that's my friends equipment at his garage but I will be taking it to a garage that has the vcds tomorrow and then I'll post up the codes.

    cheers Jay
