Hey I'm new on this forum. I'm 15 and turning 16 in a week. My mom died so i got her car. It's a '93 525i with 63,000 miles on it but there seems to be electrical problems. For example, the brake lights burn out very quickly and the brake light circuit warning goes on yet the brake lights still work. Also the Interior lights dont go on even though all the fuses are working. The last problem is the check engine light goes on only when you go up hill. Any ideas?
