Multiple Electronic Issues - E87 130i

[walkie86]

Hey guys - relative n00b to Bimmers so need some advice on where to start. I have a 2006 E87 130i manual with iDrive.

Today on my drive to work, my rev counter suddenly dipped and a 'Cruise Control Failure' warning came up. The car continued to work but the warning was on for about 15 minutes until I parked.

When I parked, I put her into reverse and a 'PDC Error' came on, and parking sensors wouldn't work.

Left her parked for 8 hours hoping they'd go away but upon returning to the car and leaving my spot both errors came back.

Then on the drive home and I had another warning that came on, "Electronic Management Failure - unable to complete journey" or something like that (it went away after a minute before I could get a photo).

The thing is, the car still drives fine (no limp mode) but some of the electronic functions are impaired.

Any ideas what might be wrong or where to start trouble shooting?

Battery

Also for shits and giggles check your drive belt.

Thanks mate. Will check the battery in the daylight tomorrow. No issues starting though.

All sorted. Was water in the driver's side rear boot well where the PDC module sits. Took it out, dried it out in a bowl of rice for a few days, got the water out of the boot well and refitted - all fixed.
