Hi All,
I have a 1994 Audi 100 S (135K miles) and have been having an ignition switch problem for quite some time. I have to turn the key slightly counter-clockwise before I can have the wipers, turn lights, etc, working. Also, my radio/speakers make a slight whirring noise for a few seconds after I turn the ignition off.

Recently, I had the airbag light come on, and after pulling codes, it showed:

00588 - Airbag Igniter; Driver Side (N95)
32-10 - Resistance too High - Intermittent

00532 - Supply Voltage B+
07-10 - Signal too Low - Intermittent

The mechanic said the clockspring went bad and quoted $900 total (the part alone was $505!!!). I took it to another place, and said they found no slip-ring noise while turning the steering wheel (apparently the clockspring is also called the slip-ring?) and so the most likely would not replace that first because it was expensive. They said they would fix the ignition switch first to see if the airbag problem disappears.

My question is: Could the airbag open-circuit problem be related to a bad ignition switch?

Any help will be appreciated!

Thanks in advance,
Pradeep

 

I have the same problem on a 98 A4... I wish someone would let us know what to do! When I figure it out I will post my results. I'm about to put an ignition switch in.

 

I would start with the ignitnion switch but i dont think its causing the air bag fault. The problem is the fact that its sporadic so its hard to test unless its open at the time of testing. I would try putting some contact enhancer on the connections at the clock spring. Alot of times spor adic faults like that are caused by connectors not making good contact. Could also be an airbag or clockspring. Clocksprings dont have to make noise to be bad.

 

They were 2 separate problems. My ignition switch was cracked and broken, so had to replace it. And the airbag light was due to a bad clockspring ($1000 to fix it ) - the part was $550. On an audi A4, it might cost much lesser though.
