Hi all

I got a F31 330d 2013 which has a annoying issue and was hoping someone in this forum has encountered my problem before.

The issue starts when using Cruise control and turning up my HK(Logic 7) sound system the speedometer starts to jump a few km/h and sometimes it feels like the car deaccelerates befriely.

The car was reporting old/worn out battery which i have replaced and coded with ISTA. It has made the needle of the speedometer jump less but haven't fixed the issue. I suspect a unstable voltage supply is the cause of my issue since it can be provoked by cranking up the volume.

Does anyone know a issue with corrosion in the power supply leads / connectors?

Thanks.
