Real weird one!

W55ksy · 05-31-2015, 02:23 PM

Ever been driving along and all instruments go blank for about 1 second, then a whole range of warnings (tyre pressure, ASC, DSC, Transmission etc.) all come up together? Car keeps driving ok.

If I stop and turn the car off, then on again - all is fine - warnings gone??

This has happened to me about 5 times in the last week - worried that something more permanent is about to happen.

Anyone experienced this and know what it is??

This sort of thing is everyone's nightmare.

Battery issues can throw all sorts of anomalies, wonder if it is voltage related.

Check the battery terminals, and also check the grounding point underneath the battery, as they're known to corrode and cause issues exactly like you describe.

Main power cable to the junction box,remove the lower passenger footwell trim and have a look up.youll see a thick red cable going into it.wiggle it around and see if it does anything to the dash lamps etc
