Repairable?
// Bench verdict
Repair where the board allows; where water damage is terminal we clone your data to a donor unit instead. The E90 in our job log is the honest example — repaired, worked briefly, died, so the data went onto a donor DDE and the car kept its keys and immobiliser data. You only pay for work we can actually deliver.
