Another Spun Crank Hub

I have a full on snap-on code reader in my car and its not tuned nor does it have a piggyback.

Good luck OP let us know how it goes regardless of what the yap's on this forum post.

+1. I also have Rheingold. If a CEL pops up, I don't want to have to make the journey to the dealership to find out what it is. I have no tune either. Weird, right?!

I have a 10 dollar bluetooth OBD adapter off amazon and torque app. I dont use it anymore cause I have JB4 but I used it pre-tune.

I didn't mean to hurt your feelings, my point was i used to have a code scanner in the car back when i had an fbo 335i and was constantly playing with different maps.

On a stock car, i dont see the need to carry it around with me, thats just me. My car has 15k miles never thrown a cel.

No sweat. Definitely didn't hurt my feelings. Glad to hear your car is still doing well

Thanks, good luck with the repairs. Your tech seem very knowledgeable.

Every SCH thread is like this it seems.

You're getting the car back in no time and it'll be fine. Like you said, revised parts.

Should be good to go. I wouldn't worry. There are much worse things in life.

Agreed. Even if you spin it and have to pay yourself whats the cost? 2-3k as long as it doesnt cause something catastrophic?

Why is everyone so "accusatory" for folks having an ODB Bluetooth Adapter and the Torque app?

Sure, you can buy the BMW ODB Bluetooth device and app for a couple of hundred dollars but no one seems to have issue with that. But when someone pulls out a $5 ODB adapter and free app that does MORE than the BMW product, then they must be some sort of tuning criminal! ;-)

God forbid they find a socket set or screwdriver in your toolbox! Then you really got to be up to something suspicious!

I'm sure it has nothing to do with the few guys with tuned cars that had sch pretending to be completely stock.

As for the people saying that the new bedplate theory is out the window due to a supposed SCH on a post-DEC 2015 build, I wouldn't be so quick to pass judgement. Just because you have one known failure doesn't mean the whole theory is a bust; that's silly.

Let's wait for more info and an actual confirmation.

Cary are you 100% sure post Dec 2015 non-ZCP's had the new bedplate or is it possible non-ZCPs got the new design at a later date?

All I know is that the bedplate part number changed in Dec 2015 for all S55's, in coordination with the S55 Competition Engine (GTS/ZCP). At least that's the way we interpreted this part number change. BMW stated repeatedly that the bedplate was strengthened for the ZCP/GTS and makes no mention of the non-ZCP/GTS S55 getting this change. However, the new part number is identical in the regular S55 vs. GTS and ZCP and that part number changed in Dec 2015.

This is, to knowledge, the 2nd reputable confirmed 6MT stock spun crank hub event now in nearly ~3 years of production of the S55 - pre or post bedplate. The last reported and confirmed on this forum was perhaps nearly a year ago?

This also seems like a minor spin that was readily fixable with a handful of parts, though we shall see.

There are now over 50,000 S55s produced worldwide and probably around 500 million miles driven (10,000 miles average per S55). And alot of them are well tuned, and still this pops up extremely frequently even among the tuned community.

Why does this freak people out anymore?

Not that I disagree with you, but your stats don't make sense.

You use forum stats (from your memory) and then compare it to stats of produced / possible cases world wide. The forum is a small sample size. Not to be intertwined with estimated world wide production number data. 2 6MT cars out of 100 S55 manuals on m3post vs 2 6MT and 50,000 world wide, is not the same.

Again, I'm not worried and I agree with you, but I prefer to tune when my warranty expires.

Bunch of ostriches trying to stick their heads in the sand here. Are you guys seriously knit-picking everything OP has said trying to catch him in a lie? Extremely abrasive responses, no wonder the other posters reporting these failures disappeared in short order.

This same thing happened over on the e9x m3 forums when they changed the clearance/material of the rod bearings in the 2011 cars only to have the cars spin bearings at even lower mileages. Beware of BMW "fixes".

That's understandable, but these vehicles are designed with track/race in mind. With that said, downshifting to a lower gear or driving too hard shouldn't be a worry. Especially if it's not a consistent occurrence.

The real flaw is in the construction and materials used in the production of the hub assembly & components. All these speculations of over revving, sudden accel/deceleration, build dates, etc. are just that, speculation. There are cars that spin to 9k RPM all day and don't have this issue. BMW should look into the supplier/manufacturer of their components.

Think about the Takata incidents. It's only a matter of time before more crank hub failures happen and BMW points the finger to their crank hub assembly manufacturer. By then it will be too late and the new generation M3/4 will be available.

You do realize that these apps do a lot more fun stuff than read codes?

I have the Dash Cmd myself but a quick Google search on "free torque app" provided this picture:

I understand your response, but please note I didn't mix stats. I was making two different statements.

The first is that WITHIN the community, this occurence (6mt, stock) appears to have been confirmed 2x - ever. Once a year ago, I believe. This is super rare within the forum community (stock car, 6MT). And on this car it appears to be a relatively modest problem here - it was driveable and fixable.

The second is that with the number of overall cars on the road and the miles accumulated, and the evidence we've been able to gather outside of the forum as well as inside, this should not be a serious concern at this time compared to say S65 rod bearings or Porsche IMS bearings.

Sorry if I wasn't clear and this is just my opinion.

I doubt its that cheap. Tearing 1/2 the motor down and keeping the car for a week or two. I believe @sA x Sky had 3 spun hubs and one of which he paid out of pocket, he mentioned it was around a $7,000 bill. He has since moved on to a different platform.

He destroyed his crank. Can't compare that.
