Supercharged warranty

For all you supercharged guys out there...what happens to your warranty when u get your M3 supercharged. Is your warranty completely voided or do dealers work with you?

no supercharger here... but I can confidently say, that you're warranty is instantly voided upon BMW discovering your car is supercharged. Think about it.

I don't think it's voided per say but just try and make a engine claim and see what happens then. I think they have to directly prove that the S/C caused the problem with the engine before the warranty is voided.

Of course the dealer would work with you, they aren't stupid, but just try to claim some repair costs against the warranty and you would be refused

Well, your drivetrain warranty will be voided, but not the entire warranty. Any mods you do must be responsible for the part of the car that failed. i.e., if you supercharge your car and a few days later your power window stops working...well, SC had nothing to do with that, so they should fix it.

That is how it worked with my Mustang. Granted Ford and BMW are different companies, but I believe they fall under the same consumer protection laws in the US.

Wrong. As others have said, my dealer works with me and honours the warranty for non-powertrain related issues. That being said, nobody in their right mind should expect BMW to warrant the powertrain after supercharging.

According to the Magnuson-Moss Warranty Act, the dealership has to prove that the aftermarket modification caused or helped cause the failure. However, it may not be hard to make that conclusion if you have any powertrain problems... If it's body/suspension/interior related, though, then the supercharger should not have any affect on your warranty.

I have never had to test the Magnuson-Moss Warranty Act but I would imagine that BMWNA could paint with a pretty broad brush with regards to what issues the supercharger could cause.

If you are going down the supercharger path you should be ready for all powertrain claims to be denied, but if you have a good dealer and/or good relationship with your service manager you should be ok.

However, with all that said, if for some reason you had a major electrical failure that required serious money repairs BMWNA may step in and try to say that during supercharger install/tuning you compromised the electrical system and any repairs are not covered. You might then face a risk.

It's a risk you take when you do major modifications to a car. As they say, you gotta pay to play.

if you have to ask if about warranty with a supercharger kit installed, then it clearly isnt for you. dont expect much of a warranty left once you do a mod like that to the engine.

+1 for common sense.

Your entire warrenty might not be voided, but if you suddenly have a claim that cost some big bucks I would expect your dealer to try and link that problem to your SC...

I am trying not to find out. My inspection is due in June and the stupid CEL will come on to remind me to go to the dealer. Honestly, I just don't want on of the techs driving my car.

According to my experience, there's no REAL answer to the question.
Mod friendly dealer would tell you that everything relates to the engine will be voided.
Some anal dealers would tell you that you are done with your warranty.
Anyways, never start a fight with dealer if they don't warranty your car, just bring it to other place. They can void your warranty permanently if they report to BMW.

touche. i should have specified that the warranty will be voided as it relates to engine issues. i have no doubt that non-engine related items like the suspension warranty and such will remain intact. bmw does have to prove causation in every instance.

YEAP AGREED... supercharge it at your own risk... BUT if your really worried about supercharging it cause of warranty issue i would consult the dealer first. I know a guy that did that and dealer were still a bit nah and yes kinda answer. so to those who are worried about supercharging the M i would just wait for the warranty or if you dont care about warranty SCREW IT..

all i can say is anything related to engine warranty will automatically voided. other warranty im pretty sure you can fight it.

I've had to test Magnuson-Moss and let me say, its not as easy as going to the dealer/BMW NA and saying "Prove that what I did to my car caused part XYZ to fail". Basically BMW will just refuse any work to your car and you'll have to fight them to get anything done.

I would not install any aftermarket forced induction modifications without being prepared for your dealer to void your drivetrain warranty in it's entirety. It's an absolute reality and there's no sense in denying the possibility. The additional stress placed on every drivetrain component completely justifies BMW's stance on voiding your factory warranty.

With that being said, we are fortunate enough in the US to have dealers of varying levels of tolerance. Not every tech, service advisor, or dealership will follow the letter of BMW's law. Some techs are quite reasonable and will still replace drivetrain components provided they are not related to your forced induction system directly.

If warranty is a concern, I would suggest forming a relationship with your local dealership and it's techs and service advisors, and determining their comfort level with modifications before taking the plunge.
