I don't recall a chain stretching or snapping like timing belts and I'm sure the chain tensioners are very modern and much more advanced.
Timing chains 'are lifetime parts' that stretch and need replaced eventually, in general. Then again, there's a LONG history of timing chain tensioner problems with all sorts of cars.. where the tensioner is what breaks rather than the chain, and when you're that deep, the extra $$$ of parts to replace the chain is just being smart, since it's a small fraction of the total cost of the job.

Dealer replaced driver side radiator that had pinhole that could have been caused by excessive road debris left behind in construction zone by FDOT several months prior

iDrive constantly restarting/freezing

Some times I start the car and the screen is black unless I hold the power button to reset it. Recently it started just now having volume as if it were frozen then it resets itself. Not sure what the hell is going on

Squeaky door on my F32 440i and fortunately nothing else.
Edit: And squeaky sidemirrors when they roll in.

On a side note, was looking at some coding apps on Play Store, specifically Bimmercode and Carly.

They have some cool features but reaching out to get some help on this as I don't wanna mess anything up.

Are these apps trustworthy?
Do these void the warranty?
Any personal experience, tips and guidance would be much appreciated.

I couldn't find another thread on this topic so posting a new one.

cheers.

I have used Bimmercode and been very happy with it. Easy and straightforward to use. There is a separate forum dedicated to coding and lots of info here: https://f30.bimmerpost.com/forums/fo...play.php?f=429

https://www.autoevolution.com/news/b...ps-129912.html

https://www.bmwblog.com/2018/10/31/b...88-horsepower/

these changes tell me that, considering the lengthy recall lists (just 100 recalls = millions $) BMW engineers in Munich scrambled realizing that the common sense worse scenario issues turned out the norm. Shredded turbos, fail chain, fail piston, fail bearings, fail cylinder all = full engine replacement. Each time BMW lovers floored it, they proved the cautionary folks right, and engineers wrong. They got power right, but not life cycle management (hey even Ferrari missed that this year in F1). The idea of reversing the chain and belt location to bring vibration to center of car mass, as well as - stupidly- keep it cleaner, turned out hubris as any troubleshooting now involved hoisting the engine. Solution? redesign that with 30 less moving parts in TU1.

as if not enough, thermal issues plagued the engine deck, and even the less powerful N55 got hot enough to warm up overnight my garage at 0 Celsius. Solution? redesign the deck, crankshaft bearings AND pistons and cylinders, metallurgically better alloys, thicker walls in critical punch hole location (is it Honda in F1?) and thermal improvements with smarter cooling per stroke. suddenly, the engine can handle 350 bar...

when did they actually do that for the N54 and N55? it has not happened actually. The B58 release coincided with MB swooping by BMW, Audi as well surpassing it in sales, etc. Cause and effect.

either case , those that tuned up the B58 rapidly discovered issues that were almost unheard off on the prev gens. Smooth as butter, fast, but piss poor reliable.

Hopefully BMW extends warranty to ALL B58 owners, not the least due to stringent EU and German consumer protection laws. But i have a feeling that they will do swaps quietly and they are trying to release the TU1 quietly as to not reveal the original B58 as a 2 year wonder...
where on earth did you get all those assumptions? where are all of the failures you're talking about? BMW wanted to make more power and reduce emissions, so they made design changes that increased fueling and engine efficiency. none of what's in the articles indicates that there's a reliability issue. it actually mirrors what most automakers are moving towards with turbo manifolds integrated into the head, more radiators, and higher flowing hpfps.

Does anyone have any knowledge on CPO expiration on higher mile vehicles?

Vehicle has nearly 2 more years of factory warranty left but at 48k now and is a CPO (1yr/unlimited mileage). Does that mean the day I hit 50k my 1yr countdown starts or does that mean when I hit 50k, Im in CPO land (less coverage) but still get the remaining 2yrs of factory warranty and 1yr additional but in the form of CPO coverage/terms.

I was told if you hit 50k before the warranty expires you are in CPO land with CPO coverage and 1 year countdown begins.

Has anyone had their valve cover replaced due to some internal crack causing smoke out the tail pipe? Apparently this is becoming common on the B58 and quite a few in the dealers are experiencing this issue with smoke out the tail pipe and catless guys will obviously see more smoke. It has something to due with the PCV built inside the valve cover.

That's somewhat common in general. PCVs are prone to fail. It would be nice if we could run a valve cover to a catch can or something instead of just replacing a component that'll fail again, especially with increased crankcase pressures from tunes and other mods. Just sucks that it's integrated into the valve cover.

Options like the BMS catch can are nice but still rely on the internal PCV to function properly.

Has anyone seen these 2 codes? Primarily the first one. The second code, Google says: Fuel tank ventilation system, 2nd inlet point: Malfunction
But really nothing on the first code.

EDIT: taking it into the dealer tomorrow (after flashing back to stock). I cleared the code last night before parking and sure enough, within 5 minutes of driving to work it came back on.

2017 340i with 10K miles.

As for the engine, no issues as of yet.

I did receive a low coolant warning for the turbo radiator. The air temperature was extremely hot that week -- ~100F -- so the issue was attributed to the weather.

For the car:

- Speaky down seal issue which the dealer addressed per the service bulletin.

- The car did throw a back up / side camera warning when in shifting into reverse. The backup camera worked, however, the side cameras didn't. Dealer "reset" the camera system which corrected the issue.

Hot weather won't cause a low coolant warning. Check both of your coolant tanks. Only one has a sensor so the other may be low too.

44k and no issues especially with the motor.

Only issue i have is while accelerating, there is a tin can ticking type noise. At a stop it's gone, cruising with no real throttle input it's gonna. And it does NOT increase or decrease with rpm.

I'm having massive trouble finding out what it is.
