Hi everyone...I am usually a lurker, but I've got a serious problem with my 1998 528i. Although from reading the posts I feel it may be an ignition switch, I want to run my probs by you guys.

Last week, my battery died. We naturally jumped it, following BMW's manual's guidelines. After learning the battery was bad, I replaced it with a new one (non-BMW brand.)

Everything seemed smooth until that night when the AIR BAG light began randomly appearing on the dashboard. Well, a few more days past and then the AIR BAG light stayed on. Yesterday, the mulit-function steering wheel began not to work, so no radio controls, horn, etc...

Today, I took it to a local European import shop (non-dealer) mechanic. They tried to hook a diagnostic machine up, but the diagnostic machine displayed error after a few seconds. So the mechanics told me that it was likely that whomever jumped started my car, short circuited something and there is burnt wire somewhere. They want to charge me about $300 to find the wire.

Well, I told them I'd think about it. So I get back in my car and start it to head home and find the radio and clock no longer work.

So I am clueless to my problem...any help would be very much appreciated.

And if it is the ignition switch, is there a website that details how to replace it? I need help because a $300 repair bill is way too much during the holiday season to swallow.

to "reset" the electonics on your car, try this: Disconnect your battery for about 20-30 minutes, and then when you re-connect it, connect it in "one touch". Meaning, don't use "trembling hands". If you 'tremble', you send pulses of electricity thru the circuits, that can set them the wrong way.

So one touch only when you re-connect. And make sure the key is out.

A big thanks to all of you because it was the ignition switch. Changing it out cured all my woes.

Ignition switch??? Thats too strange...
Did a faulty switch drained the battery? Thats a connection I can understand, but the other symptoms?
How'd you figure ignition switch?

I have a funny feeling that this is what happened:

They replaced a good ignition switch...
In order to replace a switch you need to disconnect the battery...
It takes more then 30 minutes to finish the "repair"...
Then they reconnect the battery, and voila!...
They think the switch was bad, but actually they just reset the battery!
:lol
Too funny!

The ignition switch is a weak point in the e39. It causes all manner of electrical gremlins in the accessory side of the switch when it fails. It is very likely that it was indeed the cause of his various complaints.
