The comments on TikTok and my DMs suggest this is unfortunately a fairly common problem - my guess is especially on V8s where it may be donkey work? I can't imagine the workshop foremen are checking over basic things like spark plugs - more worrying about whether the appies are not messing up bigger/higher stakes jobs. This is the only working theory that makes any sense.

Compared to the F90, the G90 does feel a bit hit and miss. Its insanely quick for something as heavy as it is, but it doesn't feel fun at all to drive. The F90 really was peak BMW M car of the turbo generation, I'd hold onto this if I were you for life.
I went for a ride in the G99 Touring and its absolutely massive. Feels like you in a boat on wheels. Don't really like the way it looks either as its giving too much of Mercedes R Class Vibes from a few years back which was more or less designed to be a hearse.

F90 Time:
This has cost an average of R42000 a year including all performance, cosmetic and out of warranty items INCLUDING motor plan extensions, which I feel you have to include. Using the very scientific method used in the Alfa thread, this is 'two car installments' at current value and just under 1 car payment for a G90 M5 on the beloved 72 months 30% residual model
or 30% less than 1 'actual' G90 installment (ie 60 months, no residual)
In "reality" this again more like a R23K per year car to run if you take out all my adventures with suspension, cosmetics, CS bits and forged wheels.
I have said many times, you can own an M out of plan with no car payments OR WITH car payments but it should then have plan. I hope it is evident why this is the case
Not covered here are brake discs (these were changed in 2025 but I didn't have the invoice for it - it would be on the CIA) as well as the headlight that was replaced under plan for having a blown DRL LED driver. It also includes the supply of the wrong tyres that the workshop then just blindly fitted (Pilot super sports instead of PS4S) and they gave me a letter to state that there would be no issues with motorplan since they supplied them LOL. It irritated me not having matching front and rear and then afterward they could only supply PS4S or P Zero Corsas for my rears so I just sold the fronts and did the P Zeros which are on the car until now
That being said, BMW is often consistently the cheapest on tyres and on oil services somehow. I will also say that between brakes, my light change and a few other items, I got plenty of value out of those plan extensions (not changing plugs and half-assing the coolant bottle job notwithstanding).

One more maintenance update:
With 10,000 km to go on the CBS indicator, of course it was time for an interim oil change.
I had been playing with the idea of a switch to Motul as well as to 5W-40 oil. The typical OEM BMW dealer oil is a 0W-30 (LL-01 FE), which is heavily optimized for US fuel economy and emissions as opposed to heat resistance and bearing protection. Direct-injection engines also face the risk of Low-Speed Pre-Ignition (LSPI) something the S63 in the F90 is NOT totally immune to. There is also oil thinning due to unburnt fuel dilution (and over an absurd 20,000 km factory service interval, that becomes a serious concern for bearing wear).
There are numerous claims online that the F90 isn’t specced for 5W-40, but this is simply not true. US threads frequently state that the car needs to be rebuilt with bearing clearances to support 5W40 but European and German manuals approve 5W-40 for hotter operating conditions. The US mandates 0W-30 for emissions and compliance.
Lo and behold, our very own South African owner’s manual lists (on page 335) 5W-40 as a fully approved spec LOL. Before anyone comes at me for this, bear in mind I didn't blindly experiment here. As with anything oil-related, it’s practically religion or politics!
A 0W-40 requires wider viscosity index improvers to achieve that spread, which can make it more prone to mechanical shear under load. The "zero" in 0W40 only really becomes cruicial below -20 (or consistently freezing temperatures). Not something we have even during a JHB winter. Together with our local warm climate and track-duty temperatures, 5W-40 was the obvious sweet spot.
I opted for Motul once again (Alfa and Porsche are also Motul...
(I am awaiting my Motul sponsorship... any day now... like my Hogwarts letter)
I may still switch to 300V down the line depending on how the car gets used, but what tipped the scales toward X-cess was its BMW LL-01 manufacturer approval and the other required manufacturer certifications/detergent package for road use.
A few other M owners have made this swap as well.
So, off I went to Deago to grab an OEM oil filter, and then the car went to Clint at MMS Auto for the oil change.
(SUPER quick actually!)
