BMW Repair: 1999 BMW 323I 1999yp-BURNING SMEEL, LIGHT SMOKE, cars wash, 1999 bmw 323i

Question
I have spent over 1500.00 in repairs and still cant fix the problem. AFter driving and I come to a stop light smoke is coming out from the hood and smells of burning even more so if I have the air or heater on and the car at a complete stop (ex. stopped at a intersection). I have replaced the heater coil, parts to stop oil leakage and resevior, upgraded the fan and much more. I dont have the paperwork in front of me but there was much more. I dont what to do anymore. What do you suggest.

Answer
After you repaired the oil leak(if there was an excessive amount of oil)did you wash down your engine? I know it sounds odd but taking it to a cars wash and washing the engine compartment down might be the answer.Just be cautious of the electrical items and don't soak them down.
