The 10 warranty was later offered because some valve train rocker arms were found to have manufacturing defects causing premature cam lobe wear. Again, limited but enough cases and concern for Porsche to step up and make .1 owner's very happy.

Wow, this thread really covers a lot of topics. Toyota, Porsche, N54, N55 (all variants) S55, AMG, fires, company economics.

I never wrote a comment on here, but always followed those S55 problem discussions. All those useless fixing parts for the crank hub just hurt to see, if you know a thing or two about those engines yourself. And now, before we ALSO start a S55 rod bearing sh*tstorm, I registered here to tell you something wich is not told in the clip. This exact S55 was fueled with ethanol and beaten up very, very badly. Thats the reason for the overall condition and may also for the spun hub. S55 rod bearings are not an issue. They only look like this here, because this engine was abused. An S55 engine, that only ran on the Nordschleife, got its rod bearings replaced at 70k km and they were still not that bad. Therefore, for an everyday driver, those bearings will never get an issue. I mean, look at all those guys putting ridiculous torque on their S55s, and they still hold up. Btw, the crank hub and center screw design act as a "fuse" so the timing can be "twisted" a little bit. This can cause damage to the valves like here, wenn it is hard case, but it will prevent much bigger damage, that would occour with a fixed system. This engine maybe was money shiftet or there was a failure with the injection because of the ethanol. Something must have happend, that made a much to big pressure on the piston. With a fixed system, the rods would now may be outside of the block.. Cheers |

I never heard of the S55 having or needing the brief 'over-boost' function. But I can't disputed an official training manual : MDM does put the vehicle in comfort mode as oppose Sport + which changes the vehicles (throttle, DCT, etc) behavior.. |

As for spun crank hub - I want to know out of all reported cases, how many resulted in actual engine damage? Sounds like most just go into limp mode and require a replacement hub, no other damage. I only know of 1 with valve damage. |

I also highly recommend watching this video if anyone interested in learning more about crank hub design and why&how it can fail (Video title says N54 but N54/N55/S55 all share the same design and part):

Having had a n54 engine 335i, and now an M4, I cant deny the performance of the new engine. But sound wise, I miss my old screamer.....S55 is loud and interesting sounding, but not pleasing to the ear!
Downpipes going on this weekend, hoping this helps! |

I read somewhere the Ghassan Automotive 135 had a complete failure at a race last week in Texas with the VTT spline lock installed.
Not sure what the actual failure was or if it had anything to do with the Spline lock system but am curious what caused the failure.. |
