And of course, no guarantees that a SCH only happens during original 4 Year/ 50k mile warranty period. Let’s see how willing EW is to pay for $25k+ repair without doing a deep dive. Last edited by IK6SPEED; 12-07-2018 at 10:38 AM.. |

Not to get off topic and don’t want to get this thread going there, but odds were only 20% that HRC would not be President today. As thus many who would have voted for HRC voted for Green Party Candidate Jill Stein where they would have voted for HRC in 2 person race. Jill Stein votes in Wisconsin, Michigan, Ohio and Pennsylvania denied HRC POTUS. Only part of Stein votes in those states would have given HRC those States. Stein supporters want their vote back as they are source of HRC losing, against overwhelming odds. They thought the odds were against Trump with only a 20% chance. Just because odds are low, odds do not always go the way you want. I use the above as an example that everyone can understand. Please do not turn this into a political thread. I paid $4000 and changed my odds significantly. |

For the timing chain sprocket to slip it would need to have resistance on one end with overcoming force on the other. What part of the rotating overhead cams create enough resistance to over come a to pressure applied by the bolt when under power. A kickdown, upshift, or bouncing off the rev limiter should have near zero extra effect on the timing chain pressure. The same pressure to spin at 5000rpm should be the same if its in neutral, upshift or downshift. |

We don't yet know what, why or how often for this issue. Some people argue that the DCT quick/hrd shifts apply enough jolt to the crankhub bolt to make it loosen up, wear down the threads or eat away the friction discs. I am not arguing that theory. However, if wear and tear for whatever the reason is part of the cause then we could very well see more failures in the future.
I am going to drive a little less agressive, avoid downshifts, not tune for burbles until we know more. These cost me nothing. Once we can narrow down the why then I'll cough up the money for the fix. |

It's also a sure bet the incidents will not decrease in frequency. I purchased a car to enjoy it, not worry every time I drive on how not to drive it. Peace of mind. Priceless. |

It's because it's not as common as it seems. This forum exacerbates the issue because the inherent make up of the people who post. I am not worried and neither are the x% of people who have never been on the forums which is a lot of people. Ignorance is bliss and stress about a low percentage issue is dumb. Drive your car and enjoy it. |

Didn't TPG take a OEM sprocket and drill out metal to add a pin. The VTT is a solid piece. So that's not a worry. Whatever is causing the slippage is pretty powerful. The timing chain and other components must also be taking a beating. If it can break the TPG "fix" or cause the OEM set up to slip, I wonder how this will effect the lifespan of the timing chain, VANOS, or other components. |

Dyno tuning is up next, since the turbos were upgraded to Pure S2+ during crank hub installation. This M4 is here regularly, so we'll be periodically checking in to make sure everything is intact.

In response to some comments posted earlier in the thread, if anyone is regretting their purchase of the VTT spline lock crank hub solution during Black Friday let me know.... Willing to buy as I lost the opportunity to jump in the special pricing when on vacations.

There appear to be 37 boxes in a picture they claimed were the outgoing shipments so probably the initial run totalled 50 with the 37 along with those sold prior to BF. |

Any other special tools required besides the timing tools / camshaft locking and TDC locking tools? I want to tackle this |
