50i running rough

TT4.4 · 09-16-2020, 08:19 PM

Hopefully someone can give me a hand. my 50i started acting up after my crankcase ventilation lines cracked and i delayed to get them fixed. Got those replaced at the dealer. still running bad. changed sparkplugs, ignition coils, both maf sensors, all 4 o2 sensors. I have the check engine light on, but no codes only a message about emissions system test not completed. no gas smell and zero smoke. (injectors? clogged cats?)

Check engine light on? Or check control service warning?

TT4.4 · 09-16-2020, 10:54 PM

The check engine light, it had codes but they went away after I changed the o2 sensors.

Did you use a generic obd code reader?

TT4.4 · 09-17-2020, 12:33 AM

Yeah I just picked one up from AutoZone, I have ISTA-D for my N54 but never had issues with the X5. ordered the Foxwell NT510 yesterday probably should have gone the ISTA+ route

Ista-d should work for an F15?

ISTA would do way better job, Foxwell NT510 DOES NOT WORK for F-series!!!

And install the bimmerlink app

Little update.... Foxwell NT-510 worked flawless with my F15, I had rough running values all over the place. The intake pipe was completely broken where it connects to the turbos another piece of cheap plastic.

turboawd · 10-02-2020, 11:12 PM

Good to hear you fixed it

Would you be able to upload a picture of where it was cracked exactly by any chance?

TT4.4 · 10-05-2020, 06:56 PM

here are the pics of the broken pipe

TT4.4 · 10-05-2020, 07:00 PM

both sides were the same, you can't tell if they're broken or not until you try to take them off, cause they sit inside nicely but broken nonetheless

Thanks mate! I might have a look at mine too now. But how in the heck do they break like that inside... It makes no sense BMW!

Bmw's planned obsolescence is the rubber and plastics they use

Maverik259 · 01-31-2024, 12:42 PM

Just found mine broke today when replacing one of my crankcase lines. Plus the crankcase hose fitting broke off the other side so now I get to replace both. More solid plastic by bmw.

I plan on making a diy to it. I’m throwing a code right now so I’m hoping this is the cause. Some of the codes are referencing my HPFP but those are new as of a year ago.
