Good evening in the round! Audi Cabrio BJ 92, 2.3 NG with automatic transmission CEB has had a huge problem with my Audi convertible since tonight. We were on the road, until the parking in Braunschweig everything normal. I noticed when starting that the usual lighting of the control lights in the MFS is missing. it only burns briefly the display of the ABS, from the roof lock and the oil control, no more. The on-board voltage is about 10V and falls slowly against 8V. Since then, I have been forced to 60km. The spotlight is also quite dark. If the car is standing for half an hour, the battery recovers again to just under 12V. After switching off the engine, the ignition, the warning flashing system lights up 2x. For quick help I would be extremely grateful, the car is sold and should change the owner next weekend a thousand thanks in advance
