Hep/ideas required - GREMLINS

Recently had car serviced Nov 59 5.0L Supercharged (130,000 miles) and Gremlins have appeared and not sure if it is an electrical glitch or something major.

Over the last few weeks the following faults have been appearing intermittently at the same time, but when car is turned off it all clears, then re-appears a little while later during further use.

Gearbox - Can't detect anything, change up and down as normal
Stability Control - Does not work
Ride Height - Keeps asking for confirmation
Cruise Control - Does not work
Emergency Brake Assist

Batteries on their way can cause odd errors like this, if you search battery problems you should find plenty.

Check battery / alternator to rule it in or out

Have you checked:

Brake light bulbs are working and OE Osram quality?
Battery is in good condition and fully charged?
Alternator output is normal?

Unless it has been recently changed fit a new brake pedal switch.

If none of the above effects a cure then it is time to have a diagnostic scan with a good FCR. 2008 MY Java Black TDV8 HSE
