I took my car in for repairs dealer check my ECU and discovered I had tuned the car and canceled my warranty.
I had an extended warranty that had just kicked.

Can I get my money back for the extended warranty ?

Appreciate your input.

Magnuson Moss Warranty Act. Was the failure you tried to have warranteed related to the tune?

there’s enough information out there to help people understand to either detune (by way of cloned orig ecu) before they go to a dealer or not use a dealer that is unfriendly. No dealer in their right mind should be turning away warranty work because of a tune and they shouldn’t even be checking if they are decent human beings. Always check the forums for tune, friendly dealers, and if you cannot find one go to an independent.

This is absolutely not the reality of how Mercedes, or most other manufacturers work. The forum is full of stories of warranties getting cancelled. We have many threads cautioning people to remove their tunes to even have a chance not having their warranty voided.

Isn't it called status 8?

The Magnuson Moss Warranty Act is widely misunderstood. It only protects you against warranty claims being denied if you use equivalent aftermarket parts instead of the OE part. For example OE equivalent aftermarket oil filters and such, but those aftermarket parts have to meet or exceed OE specs. Modifying your car outside its factory specs is not covered by the act. A manufacturer can decline warranty quite broadly if the car was modified, because every part of the rolling chassis gets subjected to higher stress if the car is tuned. Even electronic faults could be denied, because the tune technically messed with the software and could cause issues. The ESP etc. for example will not act correctly when the engine suddenly makes more torque and power that wasn't factored into the code. You can't just go and tune the car, drive it around beyond the specs the manufacturer designed and tested it, and then expect they'll honor the warranty if something breaks. No law can force a manufacturer to honor the warranty if the product was operated outside of its specs. Most products have disclaimers such as warranty is void when opened.

All extended warranty programs are proratable for the remainder of un used warranty coverage. However "kicked"?? If your warranty coverage had come to term (the end of the either time or miles of coverage you purchased). Then no, there is nothing for you to receive.

Correct, it is.

unfortunately it is as the dealer discretion... it is why I say if you are under OEM or extended OEM warranty, do not f with the car as that just gives them ammunition to out right cancel the warranty. Seen it happen in

BMW
Audi
MB
Chevy and Ford.

In the end, you mod the car, you are gambling that the warranty work still applies. You could always pay a $250/hr lawyer see if there is anything there to make a case but that requires money (lots) and time.

And the companies that sell tunes will tell you it doesn't affect the warranty. They're quite vocal about it and some even claim the tune is invisible to the dealer. They then get very quiet when it comes to them taking over the warranty if the dealer/manufacturer denies coverage. You tune it, it's yours.
