I have a 2000 audi a-6 quattro with a 2.8. the power windows and locks moon roof and interior lights do not work. when i turn on the car it shows all 4 doors open on the disolay screen and sometimes the car chimes like a door is open or the lights are on...can anyone help. i was told it could be a self resetting relay switch or something to do with a short in the power lumbar support...can anyone help

all i could find in tha manual is that there is a relay switch that controls the windows and roof..this problem developed when my heater core was leaking and there was a lot of water on the floor boards due to this problem. i am assuming that the water shorted out something. even though there isnt a direct fuse for these things i did pull out a lot of them and check to make sure that there wasnt any bad ones.. all i could find in tha manual is that there is a relay switch that controls the windows and roof..this problem developed when my heater core was leaking and there was a lot of water on the floor boards due to this problem. i am assuming that the water shorted out something. even though there isnt a direct fuse for these things i did pull out a lot of them and check to make sure that there wasnt any bad ones..

if your car has had water intrusion then you have a wet central locking control unit(german fancy words for bcm or body control module) its under the drivers seat/foot area. If your car does or has in the past smelled like a moldy stink box and the front footwells have been any where from damp to underwater, then most likely the rubber drains underneath the battery(remove these!) and brake booster are clogged full of tree compost and filled your cowl area with water until poured into the fresh air intake where the cabin filter is, filling your passenger foot well first then the drivers side. To check, pull of the drivers kick panel(the trim panel left of your left foot when sitting in the drivers seat) and door sill, pull up the carpet as far as you can, underneath just in front of the seat is a black box, remove it from the floorboard of the car and open it. inside is the CL module, unplug it and look for corrosion on the pins and connector, if you find some replace the module(must be code with scan-tool) and clean the connectors with electrical oxidation remover and then preventer and problem solved. if your car has had water intrusion then you have a wet central locking control unit(german fancy words for bcm or body control module) its under the drivers seat/foot area.
