  1. Update after 1 week. Having displayed all the symptoms of an alternator failure (a million warning lights, disconnection of gearbox etc). The only difference was my engine did at least keep running and the brakes worked but couldn't do anything till I turned it off and on again. Mine did restart and I was able to drive 2 miles home albeit with yellow battery light and "electrical failure" showing on dash. I then risked the drive to Audi Tetbury. They submitted information and error codes back to Audi "Technical" who for £150 told me it was NOT the BSG / Alternator / Starter failure as per the warranty. They said if it had been, I wouldn't have been able to start it again... So what is it? I asked, they said they'd need to do further tests on the 2 x battery's / wiring - would take approx 4 hours! and I had to agree to pay another £750 for the pleasure. I mean seriously, how long does it take to test the voltage output on a couple of battery's?! "oh no it's much more complicated than that" I asked for the codes that they had seen and they have sent me these 23759 - U012000 Lost Communcation with Starter Voltage Converter 00C4 4K0959663 DCDC_GEN_2 Convenience System Central Module 0046 4N0907064CP 261 U112100 Data bus Missing Message There had been a shed load of standing water on the road, had driven through a couple of fords earlier on that day, I'm wondering if it had all just got a bit wet and freaked out ...Any of you OBD buffs out there? Let's see what they come back with :)
  2. First time poster on this forum, I own a 2020 AllRoad A6 C8. Looks like I'm joining an elite band! Just before New Year I experienced the initial "electrical fault" warning which I typically ignored, drove home turned off, turned back on again to check and it had disappeared. Normal story. Two days later having driven for an hour or so, almost home and same thing comes back on, then almost immedately I get a red alert warning and instruction to pull over immediately. Within seconds it cycled through every possible electrical error in quick succession and then disengages gear. Fortunately able to drift off the road safely, can't select any gears but engine remains running, electronic handbrake won't select. Killed the engine crossed my fingeres and restarted - phew. Drove home (still with yellow battery fault showing). Then started googling and came across this thread - excellent information all round. Just delivered it to Tetbury Audi this afternoon, being tailed by the mirs with tow rope at the ready (thankfully didn't break down on the way, and not even the battery warning light showing). Explained the situation and proudly produced the Warranty Extension kindly provided by @Bingomighty. The comment back from the service lady was yes, we've seen a few of these, "if" that transpires to be the problem, you may be covered. Some of them are, some are not.. They've told me it will cost £150 to get it diagnosed but will get this back if I'm covered and this is what's caused it. Thanks again to everyone on this chat.
