Step 1. Use your key to turn on your ignition switch. You can find your switch beside the steering wheel, which has four positions: that is the on, off, start and accessories. Though some cars have two off positions, the first one lets your key to be removed from the car ignition system while the second lets you turn off the car. Hi everyone, I've owned my VW Golf PD TD TDI Mk4 since new (June 2001) and whilst still under warranty the airbag light came on. The long and short of it is I believe I now need to replace the Airbag Control Unit, which I learned elsewhere is located in the passenger footwell situated upright in the pillar which "grows" into the dashboard and central console of the car. How to reset the service warning light on a MK4 VW Golf this is a 2002 model but should do all 1997 to 2004 with this dashboard.

The only way to get rid of the airbag light is to clear the airbag fault from the ecu. You can only do this with an obd scantool, but only if the 'clear fault' option is available on the scantool.
got the airbag fault light to clear and its not come back on yet. fingers crossed. all i did was unplug the little yellow plug on the back of the dashboard airbag about 30 times to clean the connectors. code cleared straight away :K: of course the battery was disconnected why i did that :K: 1. Faulty sensor One of the most common reasons for the airbag light to turn on in Golf is a faulty sensor. The airbag system relies on a network of sensors to detect a crash and deploy the airbags. If one of these sensors is damaged or malfunctioning, it can cause the airbag light to turn on.

Some time ago I had the steering wheel off, and made the mistake of turning the ignition on. Since then the airbag light has been lit, but I seriously doubt there's a real fault. I've rechecked the wiring, and was careful during all work. I'm guessing the computer saw the missing bag when the ignition was on, and just needs to be reset.

Immobiliser icon flashing. Start the car normally. (It stops promptly of course). Leave key alone (i.e. in ignition, in "run" position) - sit tight and wait for 10-15 minutes. The immobiliser icon stops flashing. Start car normally. 0L4f5C.
