Issue with RaceChip on 2023 G70 760i

[Captain Jack]

I installed a RaceChip on my 2023 G70 760i, and during a service visit, I found out the rear differential was damaged due to the extra boost from the chip. The dealership confirmed metal shavings and said they couldn’t warranty the damage because of the piggyback tune. Has anyone had a similar issue? How did you handle warranty claims in this situation? TIA

Sorry to hear about the damage...Unfortunately, piggyback tunes often void warranties on related components. Have you considered reaching out to RaceChip to see if they offer any support or coverage for issues like this?

I’m planning to reach out to RaceChip for support. I’ll see if they offer any coverage or assistance with the damage caused by the tune.
