I think mine is a piston slap issue. Currently at 80K miles. I just started my car for the first time today and it didn't make any noise. It only happens when it's cold af. Ambient was about 60F and thr car had been sitting all night. I'm not too concerned. I've read these engines have loose tolerances to reduce friction and extract as much power as possible. My car sees redline at least once a day.

At 80K and I've noticed my steering bushings feel a bit sloppy and I noticed some stress marms on my diff bushings. There are poly inserts for the diff and subframe which install way easier than replacing the actualy bushing. They're affordable too. Rack bushings are relatively easy too. I used to have an E36 328i. The bushings on these cars last a lot longer then the Bimmers.

Mine is an early '12 build, delivery in May '12. I have ~63K miles, over 60K of it turboed. The only thing I've had to change was the clutch. No other issues (knock on wood)!

On RSR Superdown springs and all bushings, shocks and fittings still looked good when I got to take a look last time on a hoist. Now of course there could be some hidden wear but I have had no symptoms whatsoever.

91k miles with no issues of consequence. The dealer changed the fuel pump because the crickets bothered them and the timing cover was a little leaky a few months ago so they fixed that too. It's getting to be about time to do some more important regular maintenance stuff like clutch/tob because it's starting to squeal on cold start ups and I'll do all of the fluids again at that time. The rear brakes (pads and rotors) were good for about 85k and the fronts will need to be done soon. Really that's about it on my mid '12 build.

Also know as the clutch release bearing.

When you push down on the clutch pedal, it pushes a rod in the clutch master cylinder that pushes fluid through lines that pushes a rod in the slave cylinder that pushes on a clutch fork that pushes on the throw out (release) bearing that pushes on the fingers of the pressure plate that releases pressure on the clutch disk thus preventing the engine from turning the shaft in the transmission.
Get the picture ........ humfrz |

Are these instances of faulty TOB , or is there something that can be done (maintenance …. lube) that can help prolong the life of the TOB ?

Problems at high milage?
Quote:
It’s a bad design. In 2017 they finally released a TSB that covers 2013-2016 with a new part. Basically they revised the bearing for the 2017 car and now they suggest you use the 2017 bearing in all years. Too soon to know if this new bearing really has improved though. New part: SU003-07349 Edit: I updated the link because I realized I posted the link to the old part rather than the new part stated in the TSB. Last edited by ermax; 11-20-2017 at 03:59 PM. |

There isn't anything you can do about it as far as lubrication or maintenance. The only thing you can do is to minimize the pressure on the bearing by not sitting at idle with the clutch depressed. In other words, when you're stopped, slip the car out of gear and release the clutch (especially when stopped for prolonged periods of time). The TOB in my 2013, with a tad over 22,000 mostly around town miles, gets quite a workout and has held up just fine ...... at least it ain't screaming at me. humfrz |

90k miles and I’ve had to replace the fuel pressure regulator and the TOB.
Pretty consistent with most cars I’ve owned with 1 engine part failing before 100k. |
