Hi everyone,

Just in case anyone experienced/experiences this similar scenario:

On a cold morning, I started my car and drove 2 blocks from my house (driving about 50 kms/h) and my engine completely shutoff while moving (just the engine lights went on). I started the car again, it started right away with no issues. Here I am thinking that I didn't let it warm up enough so I let the car warm up at a parking lot for about 10-15mins, drove out of the plaza and the engine shutoff while driving again...started it up and it ran fine...

2 days later, on a relatively warm day it happened again, twice in the same day! I have a certified series so I booked an appointment with my local BMW shop. (everyone online was saying it was just a software issue)

Long story short...the key didn't show any errors but when they did further investigations they found error 2A41 and 2A43. They ended up replacing the magnetic wheel, sensor and cylinder head. I paid the warranty deductible $50 but I'm told it would've cost $900-$1500 for the parts plus labour... so far so good but if you experience this and you're car still has warranty get it checked!

The only thing I can add is that you should not let your BMW "warm up". It is not called for and is not recommeded by BMW.

Wheel, sensor, cylinder head?? What!?

An engine if in gear can't really turn off...well I mean it's still spinning. That's why you can turn a manual car on by push starting it when the starter is gone. I'm curious if you were in gear or clutched in when this happened..

He means don't let it sit and idle all the way up to operating temperature. It's better to drive it because it heats up the engine more uniformly.

I usually start my car, let it idle for 30 seconds to a minute to allow the oil to start moving then drive away but I keep the revs below 2500rpm until the temp gauge is out of the blue. Obviously when it's freezing out you have to let your car idle long enough for the window to clear up after you've brushed it off/scraped it before you drive away.

I'm guessing it was a crank sensor issues ... if the DME does not get a good crank trigger, it will immediatly turn off ignition and fuel to protect the engine.

^^that's a good guess. Plus i've had CPS issues that didn't throw a code (as opposed to fuel, or maf, which likely would)

I idle for a minute then same thing. Never turn off your car cold though, flooding of the block will pursue!!!

Very late but here's an update: The issue happened again and this time I voiced my safety concerns to BMW Canada. They ended updating the computer software and haven't experienced the issue again....

I got this same issue with my 07 328i 6spd but the car never shut off while I was driving. Only when I was at a stopped did it shut off. I got this code a few months ago
2A43 "Valvetronic Thermal Overload Protection Warring Threshold"
I was told to get to a BMW dealership to get the computer software updated and just yesterday car shut off and the CEL stay light up the whole time. Got the code read at Ivo and got the 24A4 code and some other code. Ivo said I needed to replace the Eccentric Shaft sensor + seals and while in there might as well replace the valve cover gasket also. Approximately $1200 + taxes.

Started the car this morning though and the CEL is cleared now. Not sure what happened but I'm going to try and update the computer software at the dealer first and see what happens before replacing the Eccentric Shaft sensor
