hi fellows,
I have a question regarding my 1993 320i.....sometimes while driving I get this yellow warning light which looks like an exclamation mark ! inside a circle...which is for electronic shift control failure....at that time there is a loss of power like the vehicle is in the wrong gear....I checked one of the E30 model manuals and it says to pull over and switch of the engine and wait and start again...after doing so the warning light doesnt appear and normal operation is restored but again after sometime it comes back....initially i thought it could be happening due to excess load while going uphill but then at times i have driven on a steep road without any problem
please explain to me what is the problem in detail and is going to be expensive to get it fixed...thanks
