I just bought my first BMW had all the fluids checked, transmission is new and was also checked, engine and computer both checked everything came back fine, I drove it off the lot knowing the speedo and things didn't work. Guy said he thinks when they out the new transmission in they didn't plug up the transmission speed sensor? I doubt it as the car runs perfectly fine without any shifting problems or lights flashing on/off. It's a 1997 5 series 528i. I have reset the cluster and everything and my digital reading doesn't work either. The only one that works is the miles until my gas is empty but mpg, mph, and temp don't work. Tried resetting it too and no difference. Been looking at forums on here for 3 days and most people say it's from the sensors on the 4 wheels or the abs module. But I have no check engine or abs lights or brake or anything? It basically tells me nothing is wrong, but I still have no soeedo???
