Well, now that I'm adequately spooked about the S65 failing for no apparent (and certainly for apparent) reasons, I'm second guessing my 2012 order...
That said I've had my 2008 for 57k miles and the worst problem I've had, aside from the new DCT software nightmare, is a burnt out tail light.

The spark plugs in the engine now are BMW originals. I think I sent the old plugs back but may still have the plugs from the car when it occurred. Don't know what good that will do but can post pics upon my return as well.

I once went in for the sunroof panel that you close manually with your hand. It came out of alignment and would not close right. Guess what they said? Driver misuse and cannot be covered under warranty. I flipped! Even the manager came to calm me down and explain. I said to him, are you an idiot? How many ways are there to open/close a sunroof? you either pull back or push forward! My Camry obviously has no problem with the way I do it! Then they agreed to cover it under warranty only if I decide to fix and pay the weather stripping that was falling off as well. That was a completely separate issue by the windows which was also a defect that they would not cover. I flipped again and finally they settled with fixing the sunroof panel under warranty. I was so disgusted with them that I went to infiniti after. |

I am not talking about every part my friend...... I am referring to parts in the rotating assembly of an engine....... A rod cap not torqued, bearing too tight, wrist pin retainer clip not installed, etc. Parts subjected to reciprocating forces in an engine generally don't stand up long if they are defective, improperly torqued or improperly assembled they show up quickly!

Further, didn't the Gintani engine run several seasons before they tore it down and observed the worn bearings? Gearhead raised a good point: Were the jounals seized on the failed tie rod of the OP's engine? Last edited by CanAutM3; 01-24-2012 at 11:24 PM.. |

a rod spinning freely could also mean a worn out bearing, worn out to about 1/2 of its original thickness... unless you take it apart and visually look at it, it looks and feels like the rod spins freely...
dont ask me how i know, my rear-end still hurts on this one... |

Everything from here on in is going to be speculation, we won't know, we can only make these theories, a proper analysis needs to be done. If I could see it in person I could tell you with 90-95% certainty what the cause was and if the journal had seized, but, after the failure and the forces involved, again, one couldn't tell unless it was analyzed by a proper materials engineering/failure analysis firm. The specialized equipment and FEM software used by these firms is required to be 100% sure of causes and effects!

If they were already boosted, and went from catless, back to catted, there would have been an increase in boost......maybe too much? And of course, that also absolves AA as the car was again changed w/o their knowledge and advice, ect..

The oil used meets and exceeds all specs of the castrol 10w60 oil, but does not go 15,000 miles...
I change the oil on my cars religiously, this one included. Matter of fact this oil was changed immediately before leaving to go to AA. We can go the route of the oil is to blame but that will be immediately disproved as well. As for the cats, these were the AA 200 cell hi flow cats that we added back as an option. The software for the s/c should be the same as what was there before as I confirmed with AA after speaking to them about the incident. There reply was "that doesn't matter.". Word for word. All good thoughts. Thank you. |

Why do you think its AA kit that ruined your motor? Did you had it checked out by someone else and they told you its the kit that caused it? Or did you just blame AA because it was the last mod you did before the motor went kaboom?

Just a quick google find. Pre-ignition. Wouldn't that put added strain on a rod/piston if it was running lean? I think everyone can agree the pics posted indicate it was running lean. How lean? Lean enough to over time cause damage. How could the engine be running lean? The tune. From my understanding, the tune for this setup was changed after my engine failure. Why, if they felt confident in it from the start? Begs me to want to share more about the other first run M3's equipped with this kit but I will stick to my car and my case. Thank you. |

Hopefully AA has revised their kits after mine and no others will have this same catastrophic outcome. I wish this on nobody else.
But should I be held victim for Beta testing? $h!t happens I know, but at who's expense? Should testing and modifying a kit that was advertised as "reliable and conservative" be the end users fault when it fails? If there was nothing wrong with the tune then why would revisions be made?? . |

TISK! TISK! Active Autoworke, I know I wont be letting your products touch my car now.. unless they step up and somehow make good on this... And Mpoweredauto I feel for you man. Hope you have better luck going forward.

Losing sleep wrapping my head around this thought of a bad tune
I came to a stunning conclusion. Whereas this is just my thought, which will need to be confirmed by others, imagine this: They tuned their kits for the atmosphere in Miami, which they claim is very harsh and if it can stand up to the high heat and humidity down there it should be fine everywhere else, correct? "The addition of water vapor to air (making the air humid) reduces the density of the air, which may at first appear contrary to logic. This occurs because the molecular mass of water (18 g/mol) is less than the molecular mass of dry air (around 29 g/mol). For any gas, at a given temperature and pressure, the number of molecules present is constant for a particular volume (see Avogadro's Law). So when water molecules (vapor) are added to a given volume of air, the dry air molecules must decrease by the same number, to keep the pressure or temperature from increasing. Hence the mass per unit volume of the gas (its density) decreases." It is drastically more humid in Miami than in Raleigh. I was told their tune would work fine in my area. IF the humidity difference between the two area's is great enough the density of air would be too. This would result in more air getting into the combustion chamber than what was tuned for in Miami, resulting in a "lean" condition. Perhaps they didn't take into account geographical differences when performing their R&D. Yes the tune may be safe down where the humidity is high, but is it elsewhere? Now I can sleep.

Over-revving engines also causes stress on components. That being said, running this engine very lean is a terrible idea. Running this engine lean on a SC car is beyond a terrible idea. The plugs being "white" really doesn't prove anything either from what I understand. I didn't know this until this thread, but it makes perfect sense. It is common for cars on meth to have "clean" plugs because of the meth. Another member also supported this fact with personal experience. You should have downloaded the tune. A tuner with access to all the maps could tell you what was different. Of course, not sure how the meth ties into the system and what controls that...pretty hard to say this or that was too lean or too much timing without looking at how the system works as a whole...you could also try to track down a new version of their software vs. your old one. Probably very difficult to do now. You should have had your engine analyzed if you wanted to really know what happened for sure. You should have also addressed this with AA in a much different manner IMHO. Do you see how your theories, while plausible, are not proven? |

AA didn't want to assume any responsibility for this, for reasons unknown. Perhaps they didn't want the bad press to get out...too late.
I tried to address this with them over a year ago and even more recent. They did not help me offset the cost of repair. Once I gathered they weren't going to help me, the consumer, is when I felt it necessary to inform other potential consumers of my experience. Had I got a "Professional analysis" performed before I was convinced to revert bak to stock I would more than likely have an even better leg to stand on. Unfortunately I didn't spend the extra $$ to do so and decided the AA kit was not a safe bet for my vehicle anymore. While data analysis from my engine block from a firm may have proven some things, the fact that tunes and other misc items were changed would have thrown a fork in the middle of it. Trust me, if I could go back and have gotten a tear down from a diagnostic/forensic firm I would have! |
