Question about 2000 Audi A4

1 Answer

Ignition starter switch


you answered this this question for somebody else at the same time I was experiencing the same problem. "2000 A4 Quattro T1.8 wouldn't start and all lights worked as if the car was going to start right up until you turned the key, and nothing". Well I took your advice and changed the starter switch in the car and everything seem to work fine for a while. Then I started having little epoisodes with it, but I could get it to eventually start until last night. I know it could be that this starter switch went bad (i'm currently trying to get another one). But if that's not the problem what else could it be or what could be fryin my starter switch? You had mentioned the key cylinder as another possibility. Can you explain? Thanks!! Maynard5

The key cylinder would be a last resort - it's remotely possible that either the key or the cylinder has become worn enough that it doesn't work right. It's more likely that the ignition switch has gone out again, but if you bought a new one, that doesn't seem all that likely either. If it is the switch, and something is killing it, I wonder whether the alternator or voltage regulator is going bad on you - if it's putting too much current into the system (or if the starter is getting weak and drawing too much current), maybe that could be causing the issue. Another idea would be to check out and maybe replace the starter relay - if it's allowing too much current flow, that could cause the switch to cook too. I hate to say it, but these are all just guesses - a recurring problem like yours could be the switch, but it sounds like something in the system is just allowing too much juice through and it's killing parts of your car.

you replaced the Body control module? Ive seen a lot of those HVACs go bad. does the car have a remote starter or aftermarket alarm? It could be the ignition switch especially if somebody hacked into it for an alarm or remote starter. but otherwise id think those problems would be unrelated. did you check the fuse for the cruise? and if it has a relay, swap it with another and keep track. i dont have a definite answer for you, but the electrical portion of the ignition switch is a possibility. Good luck

20 amp ignition fuse keeps blowing

I'm curious, does this vehicle have an alarm/remote starter? If so I expect the installer didn't wire it correctly ... it was an all too frequent issue, with inexperienced installers we had .... I would first suspect any add-on device first (if any) ... In answer to your question ... I know it does have a relay (Starter solenoid is a relay and built onto the starter) As far as it being a relay or the IGN switch ... I'm skeptical.

Ignition Switch

Heheh, no sweat on trying to help you out last time, and I appreciate the info regarding what you did and how you did it. I'm sure it'll come in handy sooner or later, as there are about a half-dozen of us here that all hang together and work on our A4s:) Glad you figured the problem out and I'm assuming you were able to clean the terminals and get it to work again rather than having to replace parts. Always nice when it happens.

Nice fix man - glad you're back on the road again:)
