Hi There,

started my V10 this morning and the voltmeter didnt move and stayed on 8 volts. Car ran fine but hazzard lights didnt flash on dashboard. Switched engine off and started again and voltmeter went to 14v as normal.

Anyone know where to start with this? No faults came on the dash?
The car has had a replacement alternator and alternator wiring harnes a year ago, so dont think its this?

Get VCDS. You need more detailed information.
I would suspect a voltage difference between your front ant rear batteries. The battery switch might be involved in the display differences.
