[QUOTE="wuzzles, post: 29928, member: 2736"] I don't know if these 3 are related or just coincidence. I drive a '97 528i btw.a) In the last 1 weeks, the car couldn't crank due to flat battery and had to be jump started twice. I dont know when the previous owner changed the battery but I have learnt how to check the volt reading via cluster unlock. Usually between 12.3~12.5v before crank and about 14.3~14.5v when engine running. b) The transmission error symbol appeared if y'day when I used the tiptronic after a while This has happened b4 once or twice before but it didnt't go into fail safe y'day... just the error on the cluster light up. Pull to the side, restart the car and the symbol was gone.c) Since Tuesday night, the alarm of my car never fails to ring around 10pm every NIGHT!!! I will turn the alarm off, arm it... and it will ring about 10-20 secs later. This goes on for 2-3 times... and then it behave properly again till the next night 10pm. I notice this started when I learnt to unlock the cluster. BTW, I don't have the OBD etc.. but from the cluster, test 14 show me / cross referring the hex code online:[TABLE="align: center"][TR][TD]14.0 C781dd error memory - C7 Fuel tank sensor fuel pump side14.1 8d8806 error memory - 8d EGS data lead disturbed14.2 3F8800 error memory - 3F instrument cluster current to high14.3 d78100 error memory - d7 fuel tank sensor (without fuel pump)14.4 6F8800 error memory - ??[/TD][/TR][/TABLE]Ignoring the fuel tank sensor (which I am aware about)... is this a coincidence, a battery related problem or something even bigger?
