Dear Forum Fellows, Since the purchase of my Phaeton V10 2012, I have problems with the comfort battery, which is constantly unloading. Thanks to the forum I have solved some errors and consumer sources myself, a visit to RAPACHO 2016 gave me the certainty that my mass points are OK, because Zottel has checked them all. Since the instructions for the comfort battery change is available, I changed them myself recently and hung them to a C-teck – just like here imm I can now see that the car has a “BLUBB-BLOBB noise” in its stand. You can hear it very clearly – even my wife has made me aware of it. I clearly locate the noise under the middle wiper fixation. The “BLUBB-BLOBB” can also be heard, as a slight vibration of hitting passes through the body (… very easy to feel if you have a finger on the S I think this error has always “sucked away” my battery quite simply before I could even identify it. So – now it’s the specialists: what can it be… ? It sounds to me like a flap to which somehow can’t close and always reopens and drives … . MfG
