Thrown Rod, Detonate, Whatever

So yeah, 2016 M3, BM3 E85 just let go in spectacular fashion. Driving home in stop and go traffic, creeping along. Went to speed up and the most gawd awful sound of pops and grinding and smoke and oil smell. It really was spectacular. Go big or two home?

Waiting on tow truck. If this isn't a spun hub I can imagine what else. car still runs, barely. Smokes like crazy. CEL said low oil pressure stop what your doing and knock that shit off.

BMW roadside assistance towing to dealer

Godspeed, sir! It's highly unlikely for it to be SCH related, and there are way too many possibilities for low oil pressure. My wild guess is cracked headgasket.

Keep us posted with how things go at the stealership. If you're in the Bay Area, PM me if you need to get in touch with a mod friendly SA.

As we speak. I'm in Sacramento.

Really, you dont think spun hub? It was seriously a detonation. Had to be pistons and valves fighting.[IMG]undefined[/IMG]

try the pic again

edit: app wont let me load the pic. just imagine an oily car on a flatbed.

[NickyC]

Danger to wallet impending.

Sorry OP, best of luck.

[MNoob]

Upside - I was in stop and go traffic. Not on the freeway with oil spewing.

I doubt it, but I could be wrong. The common DTC for SCH is "Camshaft Position Plausibility". This should at least show up as a shadow code even if the failure was instant and catastrophic.

I'm also surprised you opted to tow it straight to a dealer knowing very well that the chances of warranty denial is high. I would've at least towed the car home, put the car back to stock, top off with as much 91 octane as possible, then arrange a tow to the dealership.

If you're getting her towed with the E85 tune still on, then the chances pretty much go from something like 3% to 0% in an instant.

Damn, I tracked my 2015 with a Stage 1 tune 11 days last year, lots of hard 3rd and 4th gear pulls to redline under full load. You've got me thinking if my luck is about up.

Roger that. Only a matter of time, poor luck, or bad fuel.

No built or factory engine is indestructible, especially when it's subject to harsh conditions.

TBH, I just dont have time to mess with towing here and there and elsewhere. I knew exactly what I was doing, both risk and consequence. Maybe the dealer gets a sale out of it. Just leaving there now and the new M5 is super nice.

Best of luck either way! Hoping it's nothing super serious like a hole in the block.

F90 M5 and M5Cs are indeed very nice, but might still be more cost-effective to drop a rebuilt S55 longblock if that ends up being the case. It could be an opportunity to go with upgraded turbos, as well.

Whoa, that's actually a really fair price!

That is definitely an option. Also thinking about the new Dinan shop (carbahn, or whatever). It's been a little over two hours since snap cackle pop so I need to digest this. I am going to type a good game here, but none of you can see me curled up in fetal position, twitching.

[MNoob]

Update: Gonna take a few days to get it in service and diagnosed. Talked to my SA. We laughed, we cried, we talked about the M5 on the lot. I'm curious to see what they find.

good luck and keep us posted

What is the P error code, as I have P1339 (his fault code is detected whenever the reference position of the intake camshaft deviates from the permitted position) and P1338 (This fault code is detected whenever the reference position of the exhaust camshaft deviates from the permitted position) last week?

I suspected this is a SCH, as I was able to drive in limp mode. My ECU is now locked up attempting to revert back to stock, as the eeprom is patched and will not allow writing of the boot. Tune was performed during ED in Germany, waiting word back how to revert to stock-- don't want to remove the ECU and ship to DE Also, now have a dead battery from two remote OBDII attempts to revert prior to service.

[bracer]

Doh.

My vote from the cheap seats would be the Carbahn with a pinned crank hub and a build head from headgames. They you can run whatever you want power wise and be pretty safe. You're going to need to rebuild to even sell the car, so might as well do something nice.

Thats my plan when mine goes pop. ( I did the VTT fix, but who knows)

Yeah, I've been looking at their site. I'd after figure out the logistics of it all.

To the other poster, I have no idea what codes were thrown. I didn't not check and was in the middle of rush hour traffic so didnt look at the errors on Idrive as it happened.

Yes, sorry to hear, but your case is definitely an SCH. However, let's not get this mixed up with OP's situation.

I believe you have two options to revert back to stock tune:

1. Remove DME, bench unlock, flash

2. Have the dealership do it for a fee.

Also, the battery should've been connected to a proper power supply unit, but see if you can get a hold of a Li-ion battery tender for the time being.

Any full throttle use in the last 200 miles? Any hard downshifts in the past 200 miles?

Here and there, but nothing major. It's been raining and have basically been putting around and commuting. No hard downshifts (DCT). No redline runs.

If it's a spun hub, it's similar to some of the other reports where there was nothing really identifiable about that drive. It just decided to let go.

Did I say it was spectacular? Seriously felt and sounded like a grenade went off and tore everything apart instantaneously. No joke.

Have to say kudos to you for staying this cool and taking it as well as you have thus far. I know for certain I wouldn't be this calm about it. Good luck with the diagnosis and which ever path you decide to pursue.
