I have an Audi A4 1.8TS -01, VIN - WAUZZZ8DZ1A042835 and suddenly while driving the battery symbol and a on-dash code of 51CH is displayed !
Then i noticed that the VoltMeter is down to 8 volt (or off since 8 is lowest).

But the battery is fine and i had it now for two weeks, battery still going strong. A friend came over with his laptop and we hocked it up and got the following codes:
--------------------------------------------------
Address 08 - KLIMAAUTOMAT D5 8
01542 - Yaw Rate Sensor (G202) 06-00 - Signal to High
65535 - Internal Control Module Memory Error 08-10 Control Limit Surpassed - Intermittent

Address 17 - B5-KOMBIINSTR. VDO D12
00668 - Supply Voltage Terminal 30 53-00 - Supply Voltage to low
--------------------------------------------------

Everything but my volt meter is working ( ive also noticed that instr. lights on the Climate control is only glowing)

Anyone seen this codes and what could have caused them ?!

plz...
