the coils can be finicky, and the middle ones are prone to failure so I\u2019ve got two new ones on a shelf. Since aftermarket coils are inexpensive I\u2019d consider just changing all six with the next valve adjustment.
Garage was 100% right in changing the filter, if they don't, your just putting old shit in new oil.
It matters, but not enough for you to worry too much about it. When I did my first replacement on my m2 comp, I made sure they replaced them with the * spec and sure enough, they felt great.
But on my second time getting new tires, I just went aftermarket, spent less money and got a tire that fits my needs a little better.
5W-40 is my preferred viscosity for the N52. If you are only topping off, virtually any API SL or newer oil will work just fine. If you are doing a full change though you should source a 5W-40 that meets BMW’s LL-01 specification.
As long as it’s a LL-01, you can put that in. I’m currently running that on my N52.
This piston came out of my N52b30 with around 220000 km. It was kept pristine, ran it on thrice the volume of oil additives as per the forums recommend, along with 30/70 racing coolant additive to HOAT+ approved coolant. The car was being driven moderately hard, and not on smooth roads.
Buy a new valve cover. If it isn't cracked now, it will be soon, and/or the PCV diaphragm will fail.
I actually just traded in my 2020 750i xDrive after 3 years of ownership...Had 2 fuel injectors go bad, suspension arm issues, a battery needing replacing and misc other repairs totaling 10k.
E series steering feel and steering rack put my new 2025 bmws to absolute shame. I can't stand the constant small corrections on the hwy. The steering feels lighter than a cheap Kia. All three 2021 to 2025 feel unstable at speed compared to my E92.
Bad quality plastic. Mine are same on the inside, it looks like a million tiny cracks. I'd say it's due to age and wear.
