Often the control units that are installed in the car cannot be programmed with workshop tester. If so, the control units are removed and programmed directly on the modules.

We solder out the corresponding components and program them directly as required.

You need a copy of your engine control unit, this can be made, for example, before the update at the dealer, so that your chip tuning is not lost.

Update of control units, the latest systems are often delivered with faulty software. Car manufacturers improve the software's functionality or fix software errors. Cars are then updated with the latest software.

Such an update can be carried out safely and professionally on your BMW. We only use original BMW tools so that the update can be carried out from our side without any problems.
