"Long Ignition Crank"
My car is 2 years old, has 18,000 miles and I’ve been experiencing a “long crank” more and more often, where after I press the start button it takes the car more than 1 or 2 ignition cranks to get the engine going. Unfortunately, the problem is intermittent and presents itself, if at all, once or twice a day; usually in the morning. The dealer states they are unable to duplicate the complaint. How do I get them to reproduce or acknowledge the problem? Is any data saved on the car’s computer systems? Thanks!

Unfortunately not all long cranks generates codes for the ecu to store. What you could do is have your phone do a video each time you start the car to see if you get lucky and capture it to show the dealer. I would have the video show you pressing the start button and the instrument panel so they can see when the car actually starts.
Long cranks usually means your fuel pump needs to be replaced. Bmw is all too familiar with this problem. Alan

When I picked up my car I said I plan to take a video of the car taking a long time to turn over and they said same would not suffice, as the car would need to do it on site. BS.

Hello,
I had the same problem and they fixed it! It was the fuel pump and also something with the alternator BMW is familiar with the problem as probably you notice that your car may run a little rough ( it vibrates) So tell them to connect it to the computer and the fuel pump problem should come up It took me 3 trips to the dealership until they paid attention to my complaints |

This definitely sounds like its time to replace a battery

Having the same issue come up occasionally. My buddy did as well on his 550 and the dealer had his injectors replaced. They said there was a recall on the early production of 2012 model year F10s. A recall within BMW not one that was "documented" in the system. They basically have the injectors replaced on a case to case basis when the issue comes up but other than that they just leave it as is. Dealer is getting back to me on monday regarding the excess crank

After blaming bad gas, dealer replaced my fuel pump.
Justification was around long crank (not a specific failure code). I thought this was history with the N54 engine. Guess I was wrong.

Not all cranks are created equal. Temperature, humidity, residual fuel, crankshaft position, etc. all play into how long your car takes to start. Granted there should be no excessive delay while cranking but if it occasionally takes an extra revolution of the crankshaft or two to get fired up, I wouldn't work up a sweat over it. These are still mechanical devices and there will always be running variance when starting. Just how things work.

something like this right? I replaced HPFP last year, and the engine starts with long cranks more and more. |

Meanwhile I'm waiting for the service appointment with loaner (since I don't have alternative transportation and the center is bit far away), this morning I got the engine check light in the way to work.
Didn't feel the loss of power or get any error msg on iDrive, I thought it will go away after restart.. But it didn't and I push my accelerator harder to reach the speed I want in the way back home... The ride was horrible and it was very noisy. All I thought was getting this car as soon as possible... Now the appointment is May 7th... And I possibly get rid of this car next week... Don't know what to do... hope the light is off when I trade this in... |

Sounds HPFPish. As somebody pointed out, this was addressed when the N54 was ditched for the N55. And, it was, however they're still not fail safe by any means. What is though, eh?
Regarding the OP directly, I can't say I'm familiar with or heard much about the 50i, but, naturally, this also uses a HPFP so maybe that's on the way out. That said, injectors could be a possibility. From what I've read and heard over the years though, the BMW diagnostics system is quite proactive in storing faults for the individual injectors. Hm, interesting one.

Two years old, 22K miles, normal crank time to start until yesterday. Today it took a couple of seconds whereas previously ignition seemed to be instant. I've always used premium gas from major names. Here in coastal San Diego our temperature range is small enough to be insignificant in its effect on an engine. From your posts I understand to monitor the start time, but what is too long a time? To me, the two second difference is noticeable. Were your start times steadily worsening prior to seeking service, or was it the case of the sudden change?

2 seconds is surely noticeable.
But that 2 seconds can be due to weather or other things so I would say more than 3 seconds and frequent occurs is telling, it is time to get serviced. Make sure you record the video if you can. I was recording the video before the start everyday. (and it happened almost everyday so I have like 5 or more video of long cranks) |
