sholdowa Posted March 14, 2017 Share Posted March 14, 2017 Please delete if inappropriate Hi folks, The bosses 04 TT has started playing up ( well, tbh it's falling to bits really but that's another story ). The indicators work fine if the engine is off, but won't flash when they are. Has anyone seen this problem before I start looking for bad earths all over the car??

datlow Posted March 14, 2017 Share Posted March 14, 2017 Audi? Or ? Quote Link to comment Share on other sites More sharing options...
Alfashark Posted March 14, 2017 Share Posted March 14, 2017 Check earths, otherwise Body Control Module. No recent additions like swapping any bulbs for LED equivalent, or similar? Quote Link to comment Share on other sites More sharing options...
sholdowa Posted March 14, 2017 Author Share Posted March 14, 2017 Yup it's a ragtop Audi TT. Nothing's been changed. Cambelt replacement awaits though ): Quote Link to comment Share on other sites More sharing options...
Alfashark Posted March 14, 2017 Share Posted March 14, 2017 New BCM time then, more than likely. I think you can use a second-hand one, but by the time you find one and weigh up how much life it's got left in it, plus having it re-coded to your particular car, you'd be better off getting a new unit from Audi and letting them code it for you.

mjrstar Posted March 14, 2017 Share Posted March 14, 2017 Are the hazards affected in the same way. Is it indicator on both side that is a no-go? Most of that canbus stuff ups seem to be due to resistance issues so dramas with the indicator stalk terminals are worth considering. I have no specific audi knowledge so maybe the BCM is a possibility. Quote Link to comment Share on other sites More sharing options...
sholdowa Posted March 15, 2017 Author Share Posted March 15, 2017 Sorry for the delay... customers, who'd have them! Has changed now. No flashing on indicators whether engine running or not - they just stay on solid. Hazards are fine. All indicators are lighting up in both cases. I did get a couple of flashes on indicators after checking hazards, then they stopped again for good. A bit of googling and it turns out to be a common problem - the relays are in the hazard unit, and they get gummed up. Unfortunately, the mountings for the hazards broke a couple of years ago, and it's held in with a bit of bent wire. A damn good shake and waggling of the connector block and all seem to be working. At least I know what to hit if it happens again. Most glad not to be learning cambus at my age... (: Cheers, Steve 2 Quote Link to comment Share on other sites More sharing options...
