![]() ![]() Since that time electronic units have spread to control all sort of different aspects of the car and many people called each of these units ECU's to mean Electronic Control Unit Early cars had very little in the way of electronics (if you ignore radio) but around the 1970's manufacturers starting changing engine fuelling from simple mechanical carburettors to electronically controlled carbs or fuel injection and the unit fitted to control this was an ECU - Engine Control Unit. This is the number stamped on the body shell and visible in the panel bottom left of the windscreenĮCU is commonly understood to mean either Engine Control Unit or Electronic Control Unit. I think part of your problem is a little confusion about abbreviations and the set up of modern vehicles.įirstly the VIN is the Vehicle Identity Number. It just so happens that mulitple car models can use the same label file, and they just arbitrarily chose one of them in the file name (limited by windows to 255 characters after all). THIS IS ONLY THE (somewhat arbitrary) NAME OF THE INTERNAL LABEL FILE USED BY VCDS and should not be considered an identification of the engine that's actually inside the car. Many cars have identical measuring blocks, so your BXE uses the same VCDS label file as a BKC model (but the applicable file just happens to be called something-BKC). They are the "labels" used by VCDS, as part of the VCDS software. These are only the label files VCDS uses to identify the measuring blocks and such as displayed by VCDS. ![]() ![]() Regarding the engine labels files used by VCDS: But there's always the possibility that the ECU was replaced with a junkyard unit without the km being reset at the time of replacement. If the VIN stored in the ECU and car's VIN match, but the km is different, something may be up with the odo and it warrants further skepticism or investigation regarding the car's odometer. The important reading is the odometer, unless it's been tampered with illegally. This probably means the ecu has been replaced at some point. If the immo is bypassed, this VIN data is irrelevant. I can tell you this data if I had the eeprom dump. The ECU does have the car's actual vin recorded in the eeprom but I'm not sure if you can read it using vag-com. ECU serial number and the vehicles VIN are completely different animals. ![]()
