I am the proud new owner of a 1993 Euro M5 3.8 with 61k miles. I had been looking for a while! The car was a direct import (still has the smiley headlights, original mirrors, cats, etc) from a Polish ambassador. Apparently, the importing person had some sort of diplomatic privilege that allowed them to circumvent the standard importation process. I was told the car’s speedometer face plate was changed in Poland before being exported and a code plug from a 1993 530i was installed. The code plug has this VIN: GE83905. This code plug of course is the wrong one and, although the odometer is correct, the Speedometer and Tachometer read to low, the oil temp gauge doesn’t work, the CEL doesn’t illuminate, etc. So could anyone give me a part number for the proper plug? I am assuming the best plug would come from a UK based M5 3.8 model?
I am having a high speed rhythmic hesitation that occurs at speeds above 65 MPH on the highway. It feels as if the brakes are being quickly yet lightly applied and then released just as fast. This can only be felt in the “seat of the pants”. It is no doubt an engine related hesitation as the brakes are new and functioning properly. This engine hesitation or miss occurs only with a steady throttle and goes away whenever I am coasting or accelerating. New in the last 7k miles are plugs and valve adjustment. The car passed Massachusetts state emissions with flying colors.
I have a few (OK a lot) of other questions, but don’t want to wear out my welcome! I look forward to being an active contributor to the list.
