I didn't think it would be long before I posted something wrong with my car
2005 A4 2.0TFSI
Did 700 miles the other day so not exactly a short journey, parked up overnight and tried to start it the next morning, flickering hazards/dash lights and no starting, the alarm battery (I presume) in the rear of the car was going off. Got a jump start off a friend and it fired up pretty much instantly, too it for a good drive 25 minutes or so, and then the next morning (today), dead battery again.
I made sure that the doors were locked and that the interior lights weren't on last night, which I thought was the first problem as I read online that the door locks on A4s can cause it to drain the battery as it thinks the doors are open.
I did notice the hazard light stayed illuminated once the car was locked..
After Googling a lot, it seems there is a comfort ECU under the passenger seat, which I hope it's not that but wondered if anyone else has any ideas - I have heard that door locks can be faulty and cause this but I don't think I'm getting those symptoms that are indicative of this problem. I have ordered a Bosch battery as I bought the car with a Halfrauds unit and I don't trust anything from that shonky outfit.
Hopefully it's just a dead battery....
