Z4 Fault Codes

fontana302 · 08-12-2011, 04:20 AM

Have a fault up in the instrument cluster & in Idrive regards parking brake. says take in to dealer, may or may not be working - not sure what may be the cause.

Also get a light in the instrument cluster after a while displaying a battery symbol - seems car battery may be on the way out.

Read out the following fault codes using BavarianTech, as per attachments:
9C48 looks like AC issue
A559, A3AA, 9315 no idea.

wondering what the problems are & if anyone else has experienced these.

Do you happen to have smartTOP installed? The orginal installation instructions were a bit incorrect and caused random errors in some cases in my car.

No, car is standard, untouched.

Found out today cruise control is also not working .

Cluster fault codes A559 comes from the battery being disconnected, or voltage being dropped from the instrument cluster. This could also occur if you just disconnect the instrument cluster.
