Hello dear forum community I’m really desperate…. I’ve read a lot of posts here now and I’m kind of not quite smart. I have the following problem. My volt display swollen I made a video extra times. I hope you can help me with it… Here The video: https://www.youtube.com/watch?v=oZsqH5Zz8H8 I hope you can see it. Below 50 km/h the display varies. I read according to the forum that it can be the comfort battery. So bi n I marched off and bought a normal 100mha battery to test, before I buy again Ne Volkswagen battery for 600 euros. Does it have to be an AGM? can it be because of that? Furthermore I measured the voltages and got the right start battery their 14v and the left comfort 13… something… were not quite 14. I was already in many VW workshops and got advice but everyone told me something else… Is it the alternator ? or a mass problem or li Is it about the battery ? or still the freewheel ? what I noticed. So from 240 km/h the volt indicator also wanders back again. I had once before the error occurred here. When braking lighting failure of the speedometer and ZAB. that does not happen anymore… for that the pointer wanders back and forth… And with all luck this year also the display in the speedometer died me during filming.:/ I hope you can help me. Thank you Achso before I forget it: It handle around a Phaeton W12 / Bj 2004 / 420ps / about 150tk on the clock.
