So I got my bluetooth OBD dongle today and was playing around with torque and decided to run a couple reports just to see what info it pulled. As I was reviewing it I noticed a few misfires reported in 2 (5), 3 (1), 4 (4), 5 (2) & 6 (3) under "Misfire counts for last/current driving cycles(calculated)" - but the only cylinder that also had a misfire count under the second report "EWMA Misfire counts (average) for last 10 drive cycles" was cylinder 5 (1).

Okay, no biggie those numbers are low and I had just done a cold start that had some sputtering, no immediate concerns. Then I had to run out and did 2 hours of straight highway driving, no crazy pulls or WOT but I averaged probably ~75-80mph and got on it a couple times to pass. My temp stayed normal and the drive was smooth as can be.

When I got home, my normal light ticking noise was considerably louder and I started hearing an intermittent ticking that was even louder. Unfortunately my stupid phone was attached to bluetooth on my car and I couldn't get a recording of it, but it sounded like this from a users post not long ago (sound happens only during first 3 seconds then stops, intermittent just like mine was).

This is the first time I've had any odd noises since I got the car almost 3wks ago. I took it to BMW on the 6th for its last CPO checkup and they came back saying the car was "fantastically well taken care of, in great shape" and sent me on my way (big surprise).

So I tried to pull codes using Carly (trial) and Torque and got nothing. I went inside and about an hour later came down with my cable and MHD to try to see if there were any shadow codes, again nothing. I ran the report in Torque again and saw a bunch more misfires specifically in cyl 5(34)

I decided to try my first run of data logs (2nd to third pulls, WOT) and had as many of the sensors I thought mattered selected as I could.

Now that my rant is over, can anyone take a look at these and give me some feedback? I legitimately know nothing about turbo engines or really cars that much in general (I'm a programmer/designer) but I'm trying to learn with this car so I can take care of it as much as possible. So far I've not done anything to the car except BMS DCI and cowl delete/cabin filters. I've got no clue what the injectors, plugs or coil packs look like or their condition but I know at almost 94k, if they weren't changed by the previous owner under CPO it's probably about time I did... just looking to see if there's anything else I may be missing/misunderstanding before I drop my first pile of cash into this girl.

I very much appreciate any and all input/advice/help. I've done as much learning as I can but at this point I'd much rather ask for some experienced eyes to look at this, especially with me ready to pull the trigger on my MHD tune, alpina, ppk and some coding.

Guess no one had a minute?

Sorry for the newb questions guys - but bump in case someone has a few to give my logs a quick look and let me know if there is enough info to determine anything or if I should re-do the logs with different parameters recorded.

Thanks!

That tick in the video is def not normal ....I'm no good at reviewing logs but hopefully someone can chime In

90% of the times I had misfire it was plugs. Don't really know about the ticking.

I've had misfires once, replaced the plugs and it went away. It's a cheap DIY to do and see if it solves the codes. Th ticking is weird, it's only for a little bit and then it goes away? My engine ticks a little bit too, specially when its cold. You only hear it when you walk around the front of the car. I've been told that's normal. The ticking in the first few seconds of your video is excessive tho and seems like something is off. How frequent do you hear it? Regarding the logs I'm not of much help, as I'm learning myself just as you are. Hope someone can help you out!

I get that ticking on occasion after a long drive (over an hour). It is off and on at idle, and goes away when you blip the throttle. I read in another post somewhere that it is my wastegates.

Thanks man I appreciate it! I agree that tick is not cool, thankfully I have not heard it since.

Yeah, I think I'm just gonna take the dive and get plugs+coils.. it's a drop in the bucket compared to the fun I have with this car.

Most likely going to do plugs + coils in the next week or so. That video actually wasn't of me, but my car made the exact same noise. I didn't get to make a video in time because my phone was connected to the car bluetooth and the camera couldn't access the mic

Yeah, this was after about 2.5hrs of driving, but not too hard - highway speeds around 70-80... truly hope it's not wastegates! It definitely sounds like a belt squeal to me but I'm just learning so I could be way off.

Thank you all very much for your input!

Fcp euro have good prices on Bosch coils and plugs def hit them up and do a swap ...do the cheap stuff first then see if problems re-occur

[pits200]

Ticking is normal

Since you're swapping out the plugs and coils, might as well get NGK's and gap it. As for ignition coils, I recommend Delphi or Eldor. I'm using Delphi right now. Quality and material is much better than OEM Bosch.
