BMW M4 Bootmod3 ecu reset

Non running BMW M4 arrived with us last week, from what we can tell the customer tried flashing a Bootmod3 map on with a flat battery which bricked the ecu.
Charged the battery and reflashed Bootmod3 and we had it fixed and ready to drive away.

We can tune, service and maintain your BMW M car, please get in touch with your requirements.
