If you have your car tuned..... you lose your factory warrantee on any breakage that occured due to the tune.

You gotta pay to play. If you're not willing to accept the risk, don't get your car tuned. There is no "magic answer" to tuning a car, and then expecting BMW to honor a factory warrantee if it breaks. Anyone who thinks otherwise, is a fool.

There isn't a tuning company on the planet that will warrantee your engine, transmission, rear diff, etc. Not one. BMW has been known to even deny warrantee claims on Dinan tuned cars. If you tune it.... they will find out. Either accept the risk, or don't.

From CarBahn's website:

"If your vehicle is currently covered by the vehicle manufacturer’s new car limited warranty, CarBahn Autoworks’ products are warranted for the remaining term of the vehicle manufacturer’s new car limited warranty. The manufacturer’s new car warranty is limited to 4 years or 50,000 miles (80,000 kilometers in Canada), commencing on the date of first retail sale or the date the vehicle is first placed in-service as a demonstrator or company vehicle, whichever is earlier. CarBahn Autoworks’ warranties are transferable when ownership of the vehicle into which the CarBahn Autoworks products were originally installed is sold.

If your vehicle is outside of the vehicle manufacturer’s new car limited warranty, for two (2) years from the original purchase date of the CarBahn Autoworks product, CarBahn Autoworks will repair or replace, at its sole discretion, any defective CarBahn Autoworks component. This warranty does not include reimbursement for repairs to any original vehicle manufacturer’s component(s) that may have been affected by a CarBahn Autoworks component."

In other words.... if you break your car.... CarBahn will replace ONLY their "software"..... not the parts.
