Had a Stage 1 remap to increase BHP to 225 and Torque to 370. Within 3 days total battery drain. Returned to garage who found an intermitted seat module fault 3.5AMP drain which was reset to a normalised 0.003AMPs and ok for a few days. Garage blamed remap. Remap was removed, battery checked after 80 mile journey and fully charged, running engine provided 13.6 - 14. Battery was flat overnight. Visit to Specialist Vehicle electrician and subsequent investigation found Passenger Door Module Fault. Module was replaced.

Re contacted garage. Position was "it is a know fact that when anyone has their vehicle remapped, that due to the sensitive nature of modern vehicle, other elements can be affected, as all components on a car must work in tandem. It is nonsense for any remapping company to say that is only the engine control that is affected. Further confirmed by their specialist at Audi, who said they had seen this issues in the past, particularly on high performance cars when a remap has indeed affected programming of other components and further software within the vehicle. Once the cars ECU has been remapped there are so many variables that can lead to issues and simple removing the remap will not fix these"

I would appreciate any comments on the independent garages position which is in complete contradiction to 2 Vehicle electrical specialists and re-mappers that I have visited.

Thanks

Utter nonsense that a remap would cause a failure in the seat module imo. Just an unfortunate coincidence.
