Hi Guys

I am in desperate need of help. My car battery was flat after two weeks with an ipod connected to it. So a guy at my work said he had a charger but stupidly connected it to 24v instead of 12v. he had it connected a couple of seconds. I couldnt believe it. anyway we got the car started with a different booster but now the indicators dont work, the tv screen and radio dont work and the ac fans are constanly on and the display doesnt show the temp of what it is blowing out. these are the only problems but the car now looses its charge when turned of so will need to bump it to get it going again,
please please please can anyone assist before i take it back into bmw. i checked the fuses in the back of the car and they seem fine.
thanks
greg
