Also, it's probably that they (BMW) feel that the 335I will sell more aggressively than their heavily R & D'd new M3. Reason being is because people see the 335I so tunable that you can make it very close (in performance) to the M3 for a hell of a lot less of money.

 

well if you're dumb enough to use your full name like "steven jacobs" as your screen name then you deserve to be nailed.....but I find this very hard to believe.

but -- if I was BMW I'd do the same thing! why play around and void your warranty? - just wait until the warranty is over to blow your engine, oops I mean mod your engine

 

I've been telling you guys for years that modding could void the warranty, and didn't recommend it. Nobody seemed to want to listen.

Now, it doesn't mean you CAN'T mod. That, of course, is your decision. But those who DO mod have to be willing to accept the consequences. It could also mean a more difficult resale or trade-in.

As a few posters have pointed out, though, sometimes there are aftermarket warranties available...for a price.

 

Everyone knows that certain mods will void warranty's it's just the nature of the beast.

Best thing to do is to leave the 335i bone stock but what fun is that.

 

Hah just yesterday my friend was running his mouth about the BMW/Dinan relationship and how BMW supports Dinan to the fullest and he's actually going to make money when it comes time to sell the car cause BMW loves re-selling Dinan cars cause they're so in demand....guess not.

 

It's hard to see BMW as the bad player in this, there's no reason they should have to pay for ANY warranty work which might be related to people changing their engine's behavior. They spend millions to get an engine right and then certified, and as reliable as they can make it, and they factor all that into their profitability and price.

 

I thought modding = voiding warranty automatically.
why should BMW pay for putting more stress on the engine than it was designed for? i thought the 335i owners were doing this understanding that....but guess not.

 

I agree, but I haven't seen anybody in this thread trash BMW for their policy. As a matter of fact, it appears that everyone here is in full agreement with BMW. It's just a bummer for modders. My sympathy goes out to them if they run into problems but the bottom line is, they knew the job dangerous when they took it.

 

Subaru does the same...well not printing out posts, but you can't mod your vehicle without voiding warranty. It makes sense.

 

I think people listen. But people don't take RESPONSIBILITY.

The bad thing is that when the owner does something that stresses the car and breaks something, they blame the car maker, not themselves!

What ever happened to "You break it, you buy it..." ?

Why does an auto maker have to pay for aftermarket accidents?
Why doesn't the owner just say, "I made a mistake. I'll pay for it."

Instead, people who mod want the warranty to cover their expenses. Greedy people...

 

That is why I always decided to go with Dinan. You keep the warranty but still go fast. It may cost more but WTF? Most of this revolves over the owners with Visnu's Procede Chip and the Juicebox piggyback. The V2 and V3 have raised some major red flags with people. I never intended to mod it with anything that would void the warranty. I never thought it was a bright move to do that stuff to a brand new car with a third party company that doesn't usually work with BMW.

 

The thing is though, most of the stuff that may break because of mods is normal stuff that breaks anyway, the fuel pump? That probably goes more than anything else in the car. I mean, I understand what BMW is doing, and I think its good, I would do it to, why pay for someone if they knew what they were doing?

 

That's against Federal Law. There's a little thing called the Magnussen-Moss warranty act, and one of its stipulations is that in order to void PART of your warranty for using "unauthorized components", there must be a failure, and the manufacturer must conclusively prove that the non-OE part directly caused the failure.

Reprogram the ECU, run too much boost and blow a hole in the head or coke the turbo? yeah, they can deny that claim. However, If, say, the cam position sensor or fuel pump fails, they must replace it, no matter what you've done to the car.

 

Everything breaks eventually but if you use a piggy back mod and it changes the BMW default settings so that the fuel pump is pumping way more fuel cause you override the fuel shut off at certain rpms, then it was not designed for that specific purpose, increased speed and heat add to a shorter life, and BMW should not have to warranty it. BMW has enough cars that need to be fixed under warranty, why should they fix the ones that are knowingly being damaged. You got to pay to play and modding is expensive, I lurk the e90 board and if I had to take a guess most of those cars are driven by kids who really can't afford them, act all badazz online but suddenly the **** hits the fan and suddenly you have a 50k car that has a repair bill with close to 5 digits.

Everyone makes stupid mistakes and guys love cars but I made mistakes that I paid for and kids reading Euro Tuner mags does not help, a broken bolt or blown coil overs after 5000 miles is one thing but an engine/trans or turbos is way expensive.

With what it cost to own and mod a BMW they might as well pick up a used Mustang and go crazy with that, they are cheap and easily modable and parts like engines, trans and blowers are a dime a dozen.

 

From what I understand, Dinan actually matches OEM BMW warranty. BMW no longer provides you with the warranty but Dinan will do the warranty works.
