It's the injector noise, direct injection makes that ticking noise as the fuel is injected at high pressure directly into the cylinders rather than in port injection which is at lower pressure.

Yep I believe so. N55 has a bit noise but much less than B58.

The ticking noise also sounds quite similar to engine pinging, I'm not a fan.

Yup, that's what I say, me no like whatsoever. I can't believe that this is "normal". smh

Hah! Two cars ago the manual explicitly said that that sound was normal 'when accelerating heavily while travelling uphill in a high gear' - IE: "We tuned it such that you might get semi-consistent detonation if you really get on it in the midrange. Good luck!"

Today I drove another 2017 340i MPPSK for one day. This car doesn't have the engine tapping noise, at least I can't hear it in the car. BMW changed fuel injector?

BLACK HAWK DOWN · 06-22-2017, 11:57 AM

The more I hear this while driving, is the more I'm convinced its actually Engine Ping.

I am at 2k miles now. light never came back after restart back then.

I picked up my new 340i 3 weeks ago and it had the creaking door trims. They put some "lube" stuff on the door rubbers and it's gone away. Not sure if it's a long term fix, but they seemed confident.

Long term solution is to use teflon tape instead of lubricating sprays.

dealer replaced all door guides and now car is tomb silent again. love it.

Constant coolant warnings starting popping up for me. Also my front rotors have some serious grooves in them. 14k miles. In BMW for service currently, will follow up.

Now I'm convinced it's pinging. I normally use 91 octane but I filled up with 94 octane yesterday and pinging is gone in every instance it was before.
Oh BMW...why???

Pr3dict · 06-29-2017, 11:40 AM

check engine light back. was having some stuttering during acceleration again.

I only use shell 93 octane and I still hear the pinging.

My guess? With modern engine management and sensors, they can run it right on the 'ragged edge' of detonation without undue effect. Perhaps even when you get perfect fuel atomization and a perfect flame front, it sounds just like detonation, but happening at the right time, instead of too early and causing damage? While I know it's too early to tell if the B58 will last like other engines.. but there are plenty of other high performance BMW engines that don't detonate their way off a cliff, so I'm willing to give them the benefit of the doubt.. especially while it's under warranty.

Fixed the coolant warnings, (it was full when it was saying it was low) preformed pressure test and other things and all looked good.

They didnt replace the rotors, in stead "filled them in" and "cleaned up pad residue". I dont notice the brakes performing any worse, just some noticeable grooves in the rotors.

If its that ticking sound then everyone has that
If its really pinging you would likely get a CEL..
but I would run 93 minimum anyway

Antec800 · 07-20-2017, 01:29 AM

Yep deff not pinging totally different, and you can feel a engine pinging or detonating

Pr3dict · 08-12-2017, 12:27 PM

So after getting check engine lights for daysss. The dealer replaced the manifold pressure sensor and low and bed the check engine light came back.

P10f3 is the code I'm getting. What happens is I'll by driving and the car will stutter as if it's running out of gas and then comes back to life.

This is infuriating as they have had the car 4 times now for this issue.
