Does launch control void warranty?

Pretty sure some of the older m cars it did. Anyone have details about the m2?

Launch control was provided with the car from BMW, not some aftermarket company, why would it void the warranty? You literally bought it from them as part of the car purchase.

That's valid. I swear I remember someone saying they denied his warranty work on a transmission because they launched their e60 m5 a bunch.

I am sure it was quite hard on the tranny but the manual did not say what to limit it to. It did note something about over heating the trans but I got no errors......

At M track days a few weeks ago, they encouraged to use launch control for the 8 speed auto in the new M5 for the drag race exercise but asked us not to do so for the DCT cars. The reasoning was that the auto box has a torque converter while in the DCT you could burn the clutch. FWIW.

I'm sure it won't given it's designed to take it. Just ask m2ruder
I think at M track days they just want to limit the abuse of the cars a bit and the DCT is perhaps more vulnerable than the auto box in the M5.

I think the manual is clear. It can cause premature wear but BMW wouldn't have included it if it voids the warranty.

If you wear the clutch on the DCT from launching, they'll consider it a "wear" part and make you pay for it. Same as the clutch on an MT.

I agree with those saying that it shouldn't void the warranty...particularly because the dealership enables it when you take the car in for your break-in service. It's a feature of the car.

That being said, there are limitations to warranties. Under "normal" usage can be interpreted a number of ways, and there is definitely a threshold for abusive driving. For example, a tire may include a warranty up to a certain number of miles...but upon closer inspection of the car that warranty might be voided if the alignment was out of whack for an extended period of time, or you were roasting them in a parking lot doing burnouts and donuts.

Hard launching your car, any car, takes it's toll and things will wear faster and break. Remember your warranty is only good for so long. If that part (i.e. DCT box, axles, electronic diff) decide to fail a month after the car's warranty ends...that's on you. I can't imaging the DCT or diff will be inexpensive fixes. I remember something about the electronic diffs in the old e31 8-series being a trouble spot and stupidly expensive to repair.

Does anyone have knowledge of what information the dealer is able to extract from the car's many computers that could be used against the owner? For example a counter of how many times launch control was used? OEM data logging or black box?

There was a thread about this a while back that alluded to a different model (m5, i think). It may be a thread from another forum that was talked about earlier in this thread.

Anyway, the dealer denied a warranty claim on the rear because he used LC and at other times "accelerated quickly". It was really pretty crazy. I forget the outcome but even if it was ultimately positive it took a hell of a fight and a swim through a river of $hit to get there.

Launch control is very hard on components. It's slipping the clutches to maximize acceleration. If you have an issue the information stored in the car can be pulled up and it could be denied coverage.

But..... nothing in the manual states how often or how much you can use it. They also have an overheat safety function installed to limit use when you reach that point. it comes as an option, they promote that the car has the capability and how it enhances performance. It would be like advertising that it makes 365 hp during over boost but oh don't WOT or you might void your warranty.

Really

I am sure all my back to back LC runs were not the nicest for the DCT...... But I didn't buy it to drive Miss Daisy

I agree. I say F it and have fun. I’ve only known two M cars that needed to replace their DCT’s bc of worn clutches: a supercharged E92 M3 with 640whp (older gen DCT) and an M6 race car with almost 800whp. Our measly little M2’s will be fine.

We don't have same subject here within different forumers.

If this is a wear problem. Saying that your clutch worn out less than 2 years (while warranty is still valid) because of frequent launch control. This would be considered as parts wear over time due to owner's driving habit. Some one above made a good point comparing this to a tire as well.

If car breaks or has problem that is not due to "wear" of the component, and BMW cannot prove that such problem is from obvious fault of the owner, that should be covered with warranty.

Exactly. The trans will likely make it through the warranty period just fine and then completely fall apart when it's on your dime.

The issue would be one of abuse, no warranty allows for unlimited abuse of the car. If you are launching your car at every intersection (not what it was designed for) you shouldn't expect a warranty to cover you. There is a kid on Youtube with an M2 who loves to do donuts and beats the crap out of his car and then posts videos about how he keeps breaking half shafts as if BMW was supposed to design a car for that kind of use.
