I’d stick with genuine Bmw stuff .... the previous owner put in millers / something else for the gear/diff ... correct grade and everything . After having my ins 2 done with correct Bmw stuff the gearbox felt very very much better for it . Smoother .

About 1500 miles before the ins 2 .... so still very new . Couldn’t believe the difference to be honest

Yep it’s very odd but just saying my experience with it

The 65k ZMR i recently bought had really baulky - notchy gearchange from the off through 1st & 2nd whereas both previous 2 ZMRs were slick , light & easy through all gears .
I had the cdv removed & also had g box & diff oils changed to Millers & it was like driving a different car afterwards .
Fresh Bmw fluids may well have had similar effect but im happy as is

I also had the cdv mod at the same time ... so this could have also had a bearing in it . I have millers in all my other cars , it’s good stuff . Just my experience that’s all

Id say it was most likely the cdv that did it , ive changed box & diff oils along the way in previous Z4 Si . Z4Ms on wildly differening mileages with no immediate difference but a E89 23i on 127k that was notchy in 1st & 2nd when cold was improved significantly with a change of oil in the gearbox :? that was original fluid i suspect & Millers went in

My gearbox was great, all the way until I had my little accident, at which point it became notchy.
Insurance just kept saying they were known to be like that, and wouldn’t listen to my protestations...despite it being a fairly recent new clutch & flywheel.

I was going to change the input seal in the coming months however, I'm not sure if the centre bolt needs to be pre-loaded when it's tightened. Pelican doesn't state that it does though.

Both plugs freed up nicely - 20 mins to change the diff oil plus £36 for the actual oil. Indy wanted to charge me £170
