2012 X5, 98K
New battery, new throttle body, Had oil change, fixed leaky oil pan gasket, replaced water pump - all done by my trusty local BMW indi. Drove truck several miles, then truck just shuts off. Start by pressing "start button" then drove another ~3 miles, truck shuts off and would not start. Not even a crank - just a click when start button is pressed. What could be the problem? No dash lights indicating any problem, and no codes as far as I know.

Charge your TRUCK***8217;s battery, just because it***8217;s easy and eliminates lots of potential problems.

Yeah, it's supposed to be fully charged, but doesn't hurt to check either. I checked out some other forums and someone responded that having a tender overnight may help pull out the codes. Someone else suggested bad ground strap(s). I'll have them check both items tomorrow. Thanks.

UPDATE - Seized Motor

Yep, the motor broke and we are looking at a replacement. We won't know yet what happened until a teardown is done. Initial inspection does not show oil starvation. No metallics in system, so it's a mystery until the motor is pulled out and inspected.

Wow, that seems like there is more to the story. Which engine is in it?

Wow, that sure sucks.

How is the 'its broke & need to take it out' diagnosis get made at this point??? Is it locked?

Pretty rare event. Yours is a 6cyl too, yes?

It's locked. Won't turn. We have tried pretty much everything. No codes. As far as being rare, one person here or other Bimmer forum responded that these motors tend to seize after servicing the oil filter housing. Not directly related, overly generalized, but makes me wonder.

Don't know what the BMW designation is, but the truck is a 2012 X5 35i 6-cyl, turbo, gas. I believe this one has single turbo.
N55B30 with Twin-scroll turbo?

You said oil pan gasket in OP. That all? also oil filter housing gasket?



SIB 11 09 15 Engine Replacement and Engine Repairs


INFORMATION
New and remanufactured replacement engine assemblies are NOT pre-filled with engine oil.
After replacing an engine with a new or remanufactured engine assembly, the engine oil level must be verified as outlined in the procedure below first, before starting the engine for the first time.
If the new or remanufactured replacement engine is started to determine electronically if the engine is filled with the appropriate amount of engine oil, damage to the replacement engine can occur immediately.
The engine may have some residual engine oil from assembly, but this is not enough engine oil to properly lubricate the engine to measure the engine oil level electronically when it is started for the first time.
Further, the electronic engine oil measurement is only operational when the engine is running at its full operating temperature. Checking the engine oil without the engine running at operating temperature will lead to an incorrect or incomplete measurement.
After replacing the engine or making engine repairs that require the replacement or removal of the engine bearings, VANOS gears, camshafts, bed plate resealing, engine oil pump, engine oil filter housing, cylinder head, engine oil cooler or anything that interrupts the engine oil supply circuit of the engine requires a short oil pump and oil supply circuit priming procedure.
PROCEDURE
The following procedure applies to all engines equipped with an electronic engine oil level sensor, with or without an engine oil dipstick.
Replacement Engines:
This procedure is used when the high pressure fuel system pressure is already depleted from complete engine replacement.

After installation of the replacement engine and before starting the engine for the first time, remove the engine oil drain plug. Drain any residual engine oil from the crankcase.
Reinstall and torque the engine oil drain plug (with a new seal ring) per the applicable repair instruction.
Remove the oil filter housing cover and verify the oil filter is present. Reinstall the oil filter housing cover and torque it to the proper specification noted in the applicable repair instruction.
Fill the engine with the proper type and amount of engine oil, as specified in the applicable repair instruction.
Connect a battery charger to the vehicle.
Remove the electric fuel pump fuse. Refer to the applicable wiring diagram using the VIN number of the vehicle in ISTA/D.
Crank the engine for 10 seconds.
After 10 seconds have elapsed, stop the starter, and allow the starter to cool for 20 seconds.
Repeat steps 7 and 8 two additional times.
Reinstall the electric fuel pump fuse and start the engine. Verify proper engine operation.
After the engine has reached operating temperature, check the engine oil electronically or with the dipstick, and top up the engine oil as needed.


Engine Repairs:
This procedure is used when the high pressure fuel system pressure is not depleted after minor engine repairs and the fuel injection system needs to be disabled by removing the fuel injector electrical connectors.

If the engine has been drained prior to the repair remove the engine oil drain plug again to remove any residual oil that may have settled in the engine oil pan during the repair if the engine oil pan was not removed entirely.
Reinstall and torque the engine oil drain plug (with a new seal ring) per the applicable repair instruction.
Remove the oil filter housing cover and verify the oil filter is present. Reinstall the oil filter housing cover and torque it to the proper specification noted in the applicable repair instruction.
Fill the engine with the proper type and amount of engine oil, as specified in the applicable repair instruction.
Connect a battery charger to the vehicle.
Remove all fuel injector electrical connectors to disable fuel injection.
Crank the engine for 10 seconds.
After 10 seconds have elapsed, stop the starter, and allow the starter to cool for 20 seconds.
Repeat steps 7 and 8 two additional times.
Reinstall the fuel injector electrical connectors, reassemble the vehicle and verify proper engine operation.
After the engine has reached operating temperature, check the engine oil electronically or with the dipstick, and top up the engine oil as needed.


WARRANTY INFORMATION
Claimable in conjunction with an applicable repair that is covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks or the BMW Certified Pre-Owned Program.
Defect Code: Refer to KSD2 Claim with the defect code that applies to the engine replacement or repair that necessitated this additional work procedure to be performed

Only after an engine replacement:

Labor Operation: Labor Allowance: Description:
11 99 000 2 FRU Work time to perform the engine oil pump and oil supply circuit priming procedure after engine replacement.

Or:
Only after an applicable engine repairs:

Thanks for posting the engine repair instructions. The oil filter housing was replaced at the dealer about a month earlier. Only oil pan gasket and water pump were replaced this time, at my local independent shop.

UPDATE - It Did Seize

Motor is out and replacement motor is waiting to be put in. Today I stopped by the shop and they has the bottom of the motor taken apart. There is clear "charring" at the bottom of connecting rod #4. #2 also has similar - the rods managed to grind on a plastic piece/cover under them. There's evidence of oil starvation. However, the oil pump looks good - no evidence it started there. Tech says he won't know the source until more investigation - he is going to take apart the entire motor, if that's what it takes. Oh, they bought the truck from me.

Could be a bit of plastic broke off somewhere and lodged in the galley/orifice for that one bearing....

Aren’t the rod bearings’ oil supply all in series?

So the oil from one bearing goes to the next, and the next?

:angel:

edit. But know what you are saying...hard to say, if there are bits of say a chain guide rolling around....
