Denial, denial, denial. Talk about slow, especially compared to a 335i; OMG, it's like not even close!!!

Anyone modding their car is likely to be active on here and Bimmerfest researching.

Anyone modding their car with XEDE is doubly likely to be active on here and Bimmerfest researching.

No reports of denied warranty claims have hit these boards.

BS.

Excellent post, Steve!

Plus, I don't think there are even 54 modded 335's out there.

I also say...................

The vehicle order is contains all of the information about vehicle control units including their hardware version and all of the binary coding for them.
BMW has developed a tool that compares the vehicle order of each 335 to the known vehicle order at time of manufacture. Any deviations in the binary coding of the DME automatically alert engineers that the code requires further inspection. If the code related to boost has been altered to create a high-boost scenario, the engine warranty is immediately terminated.
To date, they have terminated 54 warranties....."""""

I didn't read the whole thread, so forgive me. I just had to call some BS.

This tech that was spoken to MAY have known some of what he was talking about, but he's completely wrong in his description of the V.O.

The Vehicle Order is a (basically HTML) list of all the options your vehicle is equipped with, and it's original status, including market (Canadian, US, German, etc..) When you retrofit new items into the car (I.E., Satellite Radio) the Vehicle Order get's changed to reflect that...

The data that's transmitted to BMW is called FASTA Data. It's transmitted after you disconnect the diagnostic equipment, not every night.

It includes many things, like all found faults, and any information you actively interrogated from the car, like the status of sensors, etc.

It includes software version of each interrogated module, yes. but It does NOT send a COPY of the software to BMW. The bandwidth neccessary for that would cripple the dealership.

BMW can NOT see things like over-rev situations and Dinan software just from FASTA data, to the best of my knowledge.

For instance:
A car comes in with a blown engine. An over-rev is the suspected cause. I have to actually remove the DME (digital motor electronics) and SHIP it to New Jersey, where they interrogate all the "black box" memory, and decide whether or not to fix the car under warranty. At this point, they would also know if performance software was installed.


Also, I'm sure he's referring to 54 terminated warranties worldwide. That'd be a LOT of modified 335's running around in one market. And he's also probably referring to over-boost detection in ALL FI'd BMW's, including turbo diesels.

I'm rambling...

But relax. BMW is not going to void your warranty after a tech does a harmless fault check on the car. At least not this year. =)

Now, if you have a serious driveability issue, and it comes up that you are suspect in CAUSING it... well that's the price you pay to play the HP game.

The great thing about Xede is that it does NOT alter the software of the car.

However, don't be naive enough to think it leaves ZERO trace. A determined engineer with your DME in his hands can find the info he needs.. max boost achieved, determined by the MAP sensor... Average intake air temp: If you're showing an average intake air temp of 50F in SoCal, something is BADLY amiss, right?

The point is: if you're going to modify your car, expect a hassle. There's no such thing as free lunch, or in this case, a free warranty after you drop in 90 more lb/ft of torque.

I think that all of this stems from the very ligitimate fear that one might install XEDE and, because of this mod alone, have a catastrophic engine failure that won't be covered under warranty due to said mod. That's a pretty big "oh sh1t" moment, I'd imagine. I've mulled this nightmare senario over many times, but I'm willing to give it a try because my lust for the next level of performance makes the risk seem worth while. The only way to know is to wait a year or so for a larger data pool, but my gut tells me that Shiv has been relatively conservative in the specs of the mod, and that the engine/trans is more than capable of handling it under all but the most abusive circumstances. One of the things that makes me optomistic is the fact that Shiv will make A LOT of money if this mod is reliable, and won't if it is overambitious in its gains. Another is that the gains seem pretty modest for a FI BMW block. I wouldn't be surprised at all if Dinan, or even BMW in minor model upgrade, produced similar gains with the same engine. I think that the ECU's nanny functions wil intervene before any critical mass occurs in terms of temp of the engine or turbo failure, but I very well could be wrong. If so, I will cry like a little girl whose parents were just murdered before her very eyes as I write out a check for a new N54.... and buy a new EVO, as the pay-to-play cost is more reasonable for that ride and it is mind blowing in its potential.

^^im having serious doubts about getting the 335 at all anymore... i dont want my engine to blow after a year, and be at fault for it

**in response to Matt**

[///Matt]

So get it, and don't put an Xede in it! it's still an amazing car you know!

[BMWPower06]

rather get an M Z4 they are around the same price or new M3, my main reason for wanting the 335 is its tuneability, last thing i want is to have the engine blow and not be covered under warranty. Shiv, stands by his claim that it doesnt interfere with any of the stock ECU signals, so how is it traceable?

I agree that a determined engineer can probably strongly suspect (if not 100% prove) something amiss. AFAIK, max boost is NOT higher than what the car can do on it's own compensating for altitude, perhaps someone can correct me if I'm wrong here.

"The point is: if you're going to modify your car, expect a hassle. There's no such thing as free lunch, or in this case, a free warranty after you drop in 90 more lb/ft of torque."

+1 True.

I've only been on E90post for like a week and I'm already tired of this constant warranty-fear bullshit.

If you are worried about the longevity of turbo engines in general, then don't get one. They require a little more 'TLC' since there's a higher potential of oil sludge or other turbo-related issues for neglected maintenance. An S4 with its NA V8 engine is probably a better choice for you than the 335. If you have more disposible income, then go with the M3.

If you are concerned about voided warranties due to aftermarket modifications, it's probably best you don't get the XEDE. Might as well not get any other mods done like suspension, exhaust, etc. either. There are no 100% guarantees. You have to personally determine whether the benefits outweigh the risk, and then go from there. That's not to say to be dumb about it. Do some research and get feedback from early adopters and other long-term users.
