Main dealers workshops would rather change complete components.
I cant see a main dealer replacing AC traction motor bearings OR fault finding on a charger down to a component level.
A lot of them play parts bingo now with ICE faults, nothing will change with EV faults apart from the repair bills will be a lot higher.
I've seen and heard stories to that effect for ICE cars as well. Rarely will a dealership 'fix' a problem - in my case, my power steering was getting firmer (Mazda strangely don't have a 'maintenance' schedule item for it), so I wanted the fluid completely drained (out the bottom, not the top as they often do by suction), flushed/treated with a special cleaning fluid (to get rid of any crud/deposits) and then refilled.
The said how about we change the pump and lines for £900+ or just suction 'drain' and refil for £100. I managed to do the 2nd and put in the special cleaning fluid (which did the job), including hand pump, for about £25.
Similarly when I wanted to clean my car's MAF, EGR and throttle body flap due to a sticky throttle response at low speeds (I also wanted to improve mpg), and I found that it was a lot tougher to do this DIY for the 1.6 petrol than the 1.4/2.0/2.3L engined cars, so again I asked at the dealer.
They again replied about having to replace the parts, nothing about cleaning, which amounts to removing a section of the air intake and spraying the cleaner over the throttle body in bursts (TB and EGR cleaning) or temporarily removing the MAF sensor section and cleaning it using a similar methodology/cleaner. They never even entertained using a cleaner, even those designed for the job from well-known makes like Wynns.
