My 318 manual E36 just recently showed this problem after driving short distance:
Once the car was parked and turned off i got in roughly 15-20 min and wanted to drive off and the starter makes a repeated ticking noise however, the lights keep flickering the electric are playing up and the clock resets itself. So after repaetedly turnign the key to try to start the car it will all over sudden go. THis happenf 2 month ago.
Next day i took it to my mates garage to get lowered we accidentally fropped the car just a little bit in the front and the car starting no problems etc. This was fine for two months.
Then out of the blue it started again. BMW thinks its a bad earth, what you guys think? DOnt want to take it to BMW as I wanna learn about the car myself and also safe cash.
Except for the bat in the trunk, any one know how to check for the other earth spots under the bonnet? Any imput is much appreciated. cheers
