A recent repair with us, BMW F10 5 Series with a very broken 8 Speed Auto Transmission. Only course of action was to send away for reconditioning or replacement. A new transmission was £12k, recon was £3k. With the age and mileage of these models getting on a bit now, the only sensible option without writing the car off was to source and replace with a used transmission.
However, with these EGS ZF 8HP Transmissions, BMW have kindly placed the Immobiliser (EWS) inside the transmission control unit. Meaning if you fit a used box to the car, it will not go into gear/ work at all. Even with genuine bmw software it will not overwrite the immobiliser code.
Which is why here at Burch Motor Works we have the genuine bmw software and various aftermarket software programs to allow us to work around these issues.
We reset the immobiliser code to a factory state using our aftermarket software, then programmed the transmission to the vehicle…. take that BMW ?
Finishing off by replacing the transmission fluid & filter pan. Road tested vehicle now driving like the ultimate driving machine again… at a fraction of the cost!
We have all the gear, and hopefully some idea to save you money on your repairs… you’re welcome ?
