Our Guarantee
Lifetime Workmanship Warranty
Bavarian Bytes stands behind the quality of our electronic repair and programming services for the lifetime of the serviced module. If a failure is determined to be directly and solely caused by our workmanship, we will correct it at no charge.
This warranty covers workmanship only and does not extend to failures caused by subsequent damage, misuse, improper installation, vehicle electrical faults, water intrusion, physical damage, or any condition unrelated to the work performed by Bavarian Bytes. Warranty service requires the original module to be returned for inspection. Bavarian Bytes reserves the right to determine the cause of failure. This warranty is non-transferable and applies solely to the original customer and serviced module.

We've seen this before — and we love it.
Bavarian Bytes started because the dealership answer to everything was 'replace it.' We disagreed. Most modules can be saved, cloned, or reprogrammed — and some can be made to do things they were never supposed to.
Whether you're a shop looking for a reliable module partner or a builder chasing something custom, we're the call you make when the usual options run out.
