Hey guys, not too familiar with engine work outside of routine maintenance.

My 2013 328ix F30 is having engine issues. I would start it but the RPM would drop and it turns off. After 4 attempts it finally stayed on but it struggles, No error codes appear such as drivetrain failure

Its got 115k km (~72k miles), a cold air intake with the associated turbo inlet pipe as well. No other engine bolt ons/mods

I checked for the whining noise the previous night by revving it up to 3000 RPM for a few seconds but sounded normal to me.

Serpentine belt felt fitted and not excessively worn. Spark plugs and battery were changed about 25k km (~15k miles) ago

Do you guys think its a sign of the timing chain about to blow?

Attached the video of it starting up below

Thanks in advance for any input

My N20 began to stall regularly on cooler days (7 Celsius) when starting the engine. It would only stay on after 2-3 attempts on average. It hasn't recurred after changing the engine air intake filter. I did not see any lights or errors when this was occurring.

When I was researching the issue, it appeared the high pressure fuel pump was an issue for other people with these symptoms

Thanks boss, did some additional research and you definitely sent me towards the right direction. Hopefully my indy shop is still operating with these Covid measures lol

I don't think it's timing chain, otherwise it would've snapped and not started back up again, could be wrong. But you're just past the 72k mark so... most failures happen around there

100% i'm pretty sure your right it would break when the car gets started

ive just had the exact same issue. originally the car stalled once randomly about 6 months ago, wouldn't start at the time but after a few hours worked fine. fast forward this week and the cars doing exactly as above.

originally was no error codes but while driving the car, stalled mid use and this left me with an error code for the high pressure fuel pump. theres a few guides on youtube. ive ordered a oem bosch pump and plan to fit this week so will let you know how it goes.

just to update my issue turned out to be the in tank fuel pump otherwise known as low pressure fuel pump rather than the high pressure fuel pump that's on top of the engine. didn't really have any error messages on the car pointing to this.

two ways of confirming this. either remove the rail from the high pressure fuel pump and cover it with a coke bottle and then try starting the car and see if fuel comes out. this can also be done direct from the fuel pump tank underneath the seat by removing the fuel line and again placing a bottle there and see if fuel comes out. this should save you time identifying which went faulty as looking around seems like both can fail on these engines over time.

FWIW you can't rely on the dashboard warning lights to tell you what's wrong. You need an OBD diagnostic tool, either a standalone like Foxwell/Schwaben, an app that connects to the car via a smart phone or tablet, or ISTA BMW dianostics software.

I had the same issue with mine after i installed my MST intake. It would usually happen on colder days (canada weather lol), but it would be fine during warm weather hmm

Did you figure out the issue?
