Long story short, 2014 328d, 76xxx miles
Driving home on 11/14 my car had a "Drive Train Failure" notification and went to limp mode, pulled over to side of the road and had it towed to BMW of Beverly Hills. Gave approval for the diagnosis.
11/16 I get a call that my HPFP failed, and will be replaced under a service bulletin, but the pump would not be there till Monday 11/19. I figured it would take a day or so, but in the mean time I was going out of town for Thanksgiving.
Get a text message 11/23 saying that my timing chain snapped, and they need approval to figure out why. Its a 50/50 chance that it will be because of the fuel pump failure.
11/30 Get a text saying BMW Field Engineer will be in 12/3 for review of the findings.
12/4 get a text saying failures are not related per BMW Field Engineer, customer must pay for repair. Called right away and the service adviser could not explain much info, waiting for more info from the shop foreman. The adviser did say I should escalate this claim to some 800 number higher than the dealership, as the dealership has to comply with what ever BMW says.
To me there are a few things that are just weird;
1) How would the fuel pump and timing chain snap at the same time, especially since the car was running for a couple minutes in limp mode, enough to get me to pull over and shut the car off with out rattle or noticeable noise?
2) The dealership on 11/15 said they tried starting the car, it wouldn't start and asked for more info of the events, if you trying to start the car with a snapped chain would the rattle not be VERY noticeable?
3) How would there be a week difference between finding the fuel pump and hearing a snapped timing chain?
4) The said the engine spins freely, with no binding. How can a free spinning engine snap a timing chain?
Anyone gone down this route before? Any advice or tips? Any one escalated a claim? Just looking for some advice, thanks.

The fuel pump runs off the chain. They chain is in two pieces and the pump runs off the lower part. If the upper part of the chain failed, you'd still have fuel. If the upper didn't snap immediately, it'd even still run.
The chain of events is ok, you have to almost pull the engine to access the chain (it's at the back.)

Just curious.

Following up on this, after two months I have a final response. BMW is willing to split the cost 50/50, so my out of pocked will be ~$8k. It is something, but I am not real happy about this at all. The car did idle and let me pull over so the timing chain was not snapped at the time of pump failure. The dealership did say they tried starting the car multiple times though.
That said, anyone in the LA area have a recommendation to get a non-dealer price for an engine replacement.
