Dropping Yellow Orange Oil Pot in Tacho

Hello. Have an Audi A6 C4 with the ABC engine. I had problems with chainsaws, ABS lamp lights up, engine in cold condition with easy taping equal high speed only slowly descending. Voltage indicator went into the knees when the fans went on. alternator should be the error. New alternator pure. we have made the timing belt right away as this would soon be due. Operating voltage Stable. Error :motor saws, ABS lamp lights up, engine in cold condition with light on type the same high speed only slowly descending, still all present. Recently, the dripping ÖLkane glows yellow orange. sometimes it flashes 3,5,6,7 12 so always different. I find here only constantly something because of the red oil can and beep. Here beeps nix and it is not red but yellow or orange. See photo oil level may be slightly above max. I have now read dozens of reports and turn off soon. Can someone give me a tip. Am only hobby screwdriver but could up to date al but the oil can makes me really worried now. HHIIIIILLLLLLLLLFFFFFFEEEEEEEEE Thanks gruss Chris MFG chris
