I have a 1991 BMW 750iL with a M70 V12 it has 132000 miles on it. I bought the car used and I have no history on it. The problem is when I start the car is smokes but the smoke smells different not oily. Then when it is running usually less then a minute the EML light comes on and it stops smoke but the car runs at reduced power. My question is what is wrong and what should I expect when I take it in.
The EML light is on because there is something wrong with the electronic "fly by wire" throttles. As far as the smoking goes, the age and mileage of the car, you may need a lot of engine work because of the design of the intakes and the PCV system. Good luck and re post and/or send me a private message and you can tell me all about it.
