I’m looking for some sage advice. I bought a 2008 Mini Cooper S. It was advertised that it would need a new computer. It had a code of P0687 ECU relay voltage high. I trouble shot, and hoped that it was somehow the way ECU/DME was calculating the control module voltage. My scan tool says that the control module voltage is 25.6667 volts. I have measured voltage in several different places from the head lights to the license plate light and all I can get is between 12 and 13.0 volts with the engine off or engine idling. But, tis is only the start of my problems. I sent my DME off to have it diagnosed, and repaired. The company promised that for $999.00 they could swap out my DME and program it for my vehicle and fix the P0687. I took pictures of my old DME just for future reference. Low and behold, it was not the original DME that came with the car. I only found that out after researching a couple days ago. The DME company sent me a refurbished DME and I plugged it in and my Mini powered up and ran. The original P0687 problem came back, along with a new problem U0101 Lost communication with the TCM. I forgot to mention that My Mini is a 6 speed manual transmission so there is no TCM (at least I don’t think so) Before I send the DME I want to make sure this P0687 problem is not in one of the control modules in the car. I read about checking the coding on the CAS to make sure the battery is registered and a pletera of other diags. I bought BMW DIS V44, V57, SSS V63 & TIS V8 GT1 INPA EDIABAS DIAGNOSTIC DEALER SOFTWARE. Woah NELLY! I’ve only opened whole nother can of worms. I found that the VIN in the DME doesn’t match the VIN in the CAS. AND I have no way of knowing if the Vehicle Order that is currently in the DME is the proper Vehicle Order for my vehicle. I say that because I think this DME is possible from a vehicle that had an automatic transmission. Is there a place to find the proper original Vehicle Order for the VIN of my car? Who can properly code my DME with the correct Vehicle Order? Or should I just give up and drive it the way it is? Other than burning a little oil, and a check engine light, it runs pretty good.
