This is very correct and hopefully somebody can learn from my errors (bringing car to dealer with flash tune installed. Should have refreshed to baseline first.) I think the Enzo tune and support is 1st rate. I believe I had a lemon engine block, should not have cracked at 15k miles.

This is a good reason to go with a JB4. Pull it off and it won't be detected. I would trade the car in on something else. You will lose money also but not as much as replacing the engine.

By the way, it seems to me that it is a very bad idea to do these types of mods with a lease car... Last edited by dglende; 09-02-2016 at 10:10 PM.. |

If you get super lucky maybe the dealer forgot to input your case in the system. Flash to stock and go to the furthest bmw dealer you are able to go to and play dumb

r.e. the comments that this just HAS to be a manufacturing defect to crack the block - if he is losing a liter of fluid a month, he might get enough into the cylinder at one time to hydro-lock it, causing the crack (and probably a bent rod, or at least damaged bearings). I'd be looking for a complete takeout engine, assuming this one is largely toast.
And one of those threads that really conflicts me - on one hand I feel for the OP, but all the suggestions about how to pass this off to another buyer, or hide the mods from the dealer do seem to be outright fraud - bad karma and a discredit to the more honorable tuners out there. This isn't a case of a dealer trying to weasel out of legit coverage - it was quite clear that these mods would void warranty (regardless of whether it actually caused the fail). I fear that every one of these cases makes the dealerships that much more likely to be defensive and litigious with all of us, less likely to goodwill anything. As many have noted, once you mod like this, you are taking on the risk to the engine and drivetrain. |

this thread is filled with bad, incorrect information.
A piggy can be detected just as a flash tune can be. They look at the boost levels, speed limits, A/F ratios, etc... If you have a serious issue which needs BMW NA to become involved, they will read all the hidden codes and you will get busted. Benefits of a piggy vs flash: -Piggyback doesnt pull the DME tamper code - downside is you cannot increase speed limiter - Dinan is supposed to take care of support costs if they are the cause. Reality is, dinan is so conservative you shouldn't get an issue, but it might happen if you run a DP or other mods. Even than, Dinan can say your other mods caused the issue. Those complaining about enzo, it's no different than any other flash tuner. They have to crack open the DME to get to the board. If this is something you are complaining about, you should of known what you were getting into before getting a flash tune. They all do the same thing. I have had 3 different ones and a few piggys and ENZO is the most reliable and produced the most HP on my car.

Any tune can be detected as out dme's show bmw NA the afr and other values. I also have Enzo's tune and i couldnt be happier with it as far as drivability, power and the features. If you didnt want your tune to he detected. Should either stayed stock or hit up dinan and suffer with being slow

I know this post is really old, but detonation can cause cylinder cracks.

I agree with the fact that tuning these cars carries a risk. I don't think Dinan is particularly slow- perhaps slower than some of the other mentioned solutions. I went with Dinan purely because the cost is nothing when it gives me peace of mind with the warranty - I don't need my daily driver to be the fastest car on the road, I just wanted a little more oomph while retaining OEM driveability.
If I decide to take this car further and Dinan doesn't meet my needs then I'll make the appropriate choice. Fact is two consecutive 80 to 140 rolls with an M4 and sitting right there with my car very slowly pulling away above 120 reinforced my decision. It all really comes to choice and what you are looking for. |

Wow I can't believe people still think they can hide stuff from the manufacturer. If they want to find out they will. They can look back at data and see your boost was above stock.
Anyway, it's pretty dishonest to try getting the manufacturer to pay for a modded car. If you mod, you need to take responsibility for what could happen. Do I believe that the tune caused caused this guy's problem? I don't know what kind of tune he had or how hard he was pushing it? Maybe it was a bad tune? Probably wasn't the tune though, but it doesn't matter. Learn from this guy's mistake and don't do it unless you are willing to spend big bucks on repairs. |

Hey everyone.. Sorry I have been away for a little while from the Forums.
I would be getting BMWNA involved in this case for sure before your pull the plug on paying out for the repair. Flash Tune, JB4, or any sort of Tune.. Return it to stock or not.. BMW will be able to pick it up through the FASTADATA that is sent back to HQ when ever a vehicle is scanned. HQ can see more data than us techs can as well. BMW lately has been Cracking down on tunes in vehicles including able to detect piggy back modules such as the JB4. Also in the case BMW has to prove to you that the Tune was the failure of the component. If they cant prove it, they half to cover it. that being said BMW has millions of dollars in engineers and lawyers who will most likely find a reason to back up their claim. I sure hope BMW covers this repair for you to be honest. It is sad to see this happen.
