moin has quite a strange phenomenon: -open car with FB drive -place motor off -stegs off -close the door -> inside lighting goes SOFORT off -lock over FB does not go -close to (mech.) -after that the opening via FB does not work -door on -ignition! -door to -> inside lighting does NOT immediately -lock over FB works again ??? can this be at the change of the radio? from org. opel to blaupunkt? have not changed the two voltages there yet (so since uer- und flündplus) and now the hit: yesterday evening we drive, heating so at 24 degrees, and all of a sudden during the ride the sliding roof opens up (turned)!! unlying, no joke! without someone would have done anything! do you have a tip for me on both things!?
