HELP!! Weird things happened to by E90!

wonglk9090 · 10-25-2012, 08:36 PM

So I had a 2006 E90 330i 74k miles. I was driving on the freeway today and the warning light came up said "Electronics malfunction", before that, the AC was cut off and the warning light randomly light up.

What is wrong with my car??I found some posts that had the similar situation but people were saying different things.

My battery was changed 6 months ago but it is not a factory one, i changed the battery at a BMW specialized shop.

Any thoughts???

I managed to drive back home and I am going to get it fix tomorrow.

Get battery/alternator checked.

check DME wires for any frayed ones, and the couple of fuses you will see within the DME unit area.

theres a good start!

Sounds like the serpentine belt broke.
