Ignition switch issues, where do I go from here?

Recommended Posts

Hey everyone,

So the ignition switch went flaky on my 2000 986 (after taking key out, I wouldn't hear the distinct "click" - key was then difficult to get back into ignition, etc.). This is the second time this has happened to me in 11+ years of ownership. The first time, I simply bought the Audi switch, pulled out the old one, popped in the new one (with a little yoga in between) and it worked like a charm. Now, after a somewhat frustrating experience getting the second replacement in, I'm not getting the engine to turn over. I can put the key in (although it takes some fidgeting for it to slide in), turn the ignition on (all status lights turn on), but not actually start the car. When I put the key in the start position, I get nothing. At this point, I really don't know where to go. Is there a chance the ignition switch didn't get seated properly (I had a little trouble getting it all the way in) or is this likely an issue with the entire ignition component? I've seen the DIY on replacing the entire thing, but this is not something I really want to do unless absolutely necessary. Any advice would be appreciated.

- Terence

Terence:

My approach would be to get yet another Audi switch, since it's only about $10 and since you already have DIY experience in replacing it.

That would eliminate the electrical portion of the switch as the culprit if it doesn't work, and then you can diagnose it further.

As you know, the replacement of the entire assembly is much more expensive and a more involved DIY, so go for the easy one first.

Regards, Maurice.

Thank Maurice. Do the symptoms I'm describing sound like an issue with the switch or the overall assembly? I think my first option may be to just re-seat the new switch and see if that makes a difference first. Too bad it's so tight in there (and I'm a little guy!)...

I'll tell you what I did. When I took the electrical part off I put the key in and turned it back and forth in the assembly to make sure it was smooth. If it is with the electrical portion removed and it locks/unlocks the steering wheel fine I would say it is another electrical switch. There is a reason they are $10 bucks. Heavily used too of course. Everything is in that switch, the "return from start spring" included.

Hi, Terence. Is there a reference to this Audi switch? I just ran into the same problem, haven't even had the chance to crack open the Bentley to see how to take it apart, yet...

Thanks.

Hello, I am having a similar problem only My power is switched on after the key is removed. Has drained the battery once as no one arond to notice and has happened twice in two months. I thought of replacing the ignition switch first before I replace the mechanism since that is the only way the power can be swithed on, Does any one agree?

The VW-Audi part number for the electrical portion of the switch is 4A0905849B

It's about a 1/2 hour job on your back with your head in the footwell.

Hope this helps.
