VY11 Calais mystery.

[vyhbdcalais]

Hi guys, First tme on here so be nice! I came out to go to work the other day & unlocked my Calais (as every other day) only to have the drivers seat move all the way forward & tilt to cover the steering wheel. After moving it back into position the car would not start. Flat battery. No problem jump started from the old reliable VS Caprice to find it idling low & running a bit rough. Drove to work & everything fine since. Next noticed the sunroof would not open with the normal open close buttons but open on memory 1 button & close on memery 2 button. these are the only buttons that work. Everything worked fine the day before. Any ideas? Thanks

Sounds like a BCM problem or the failing battery voltage has triggered the BCM to do weird things. I would fit a new battery & at the same time when you disconnect the battery cables it will reset the BCM .

Yeah, I had a similar thing with my VYII Calais, when the battery is low its like it prioritises the electrics and then some random stuff will happen like the sunroof etc, with mine it was the seat position was different everyday then 2 days later....flat battery. Definately get a new battery and try that out. Fixed my issues straight away.
