Hi

Yesterday my car was working normally. After i parked it i forgot to turn the lights off and the power got drained. I realised later in the day but couldnt get hold of a charger until today.

Once i got the battery charged up and the car running. The SRS lamp lit up and the messages «Display faulty, visit workshop» and «SRS Restraint system defective, visit workshop»

i tried to scan the car with my icarsoft MB V2.0 but only the SRS TSM AND ESP options show up. Once i tried the obd scan i got the code U0155.

The car seems to drive fine and operate normally. The cluster is working normally as well. However on the white parts of the speedo, clock and tachometer there are black spots on the inside of the cluster. I dont know what it is but im guessing its mold as the black spots appeared after the car had been unused during the winter two years ago.

Does anyone have anything that might help to diagnose this? Thanks in advance.

 

If i try to clear the general obdll code U0155, it just comes back/stays. There are no pending codes in SBS TSM or ESP systems. And i for some reason the scanner cant link to any other system than those three.

 

I was awoken by a loud whining/whirring noise coming from the car. I went outside to see what was up. A loud whining noise was coming from the SBC unit of the car. The engine was off but the key was in the ignition. I unhooked the battery and went back to sleep. Today i went outside, hooked up the battery and started the car. Now the fault codes are gone and the car is showing no signs of the fault ever happening. Wtf is going on. I have never seen anything like this, im guessing its a grounding issue but i dont know for sure. Does anyone have an idea on how this might have happened?
