Hi, having issues retrofiting a 6WB to F10 pre LCI 2011. Got the cluster, read 35160, but in there i see only 2 short vin's no long vin at all. So i try to change only them and write with R270 but it wont do it, says i need to erase km first. So i try that, but it gets stuck, seems like R270 cant do it. It did something strange with the mileage it like reduced but by like 1000km, something very small. Anyways i replaced the VINs on the 35160, only the 2 short ones with 7 VIN digits. Go to car to try and code, but get WDBI_CPS error, seems like VIN is wrong or something. Could this be a damaged eeprom, or did i maybe not solder it good? Any thoughts what to do in this situation?
