    Hi,

    I have a weird problem with my interior lights, it only happens when ignition is on/engine running and the passenger door is opened. the interior lights (front and back) pulse on and off, they fade on and off continously until the door is closed again. if the car is being locked/unlocked they work fine, if the drivers door is opened they work fine. if the ignition is not on and you open the passenger door to get in they fade on as normal. i cant see how it could be door sensor as that should mean that it should just not work at all right? and only when ignition on? when it does it i can hear a relay click on and off behind the dash. Vag com shows no faults in central locking or anything. i have tried pulling and replugging relays, removed door card and fiddled with door sensors as i heard audi use really thick grease which can mess up open and closed sensors.

    anyone had this before? so annoying at night when someone is getting out of the car :L

    thanks

    I'd be looking for a bad earth, slip the rubber boot back between the A post and the door that covers the wiring up, I'd imagine you'll find a poor wire of some form in there

    So could it be this that is causing the pulsating, mine only does it every now and then, and when it does the door lights dont work!!

    yeh its an s2, its pretty solid just the previous owner that bodged the engine right up when putting it in, its a mk4 combi van only 30 left on the road, gets a lot of looks. and best part is my friend cant get insured, so i did and i get to drive it everywhere :)

    that link looks good, few things to try now, earth, convenience ecu and cl pump.

    my door lights (red one and puddle) fade on and off with the interiors when it happen on mine
