Many thanks for the reply Phil. I’m in two minds about taking a deep dive into this myself. I’m quite mechanically capable with head gaskets, vanos and timing chains, plus the usual requirements of swapping over suspension and rebuilding things, but I wouldn't be able to remove the gearbox on my driveway if it transpires it needs a clutch pack, bearing or bush (it only slips when warmed up - as just took it out on the hill outside my house and no issues and no new codes…).

I think I’m going to have to take it somewhere to be refurbished having read around this a lot and seen others experience with fluid and filter changes and even swapping mechatronic valves. All looks very doable in terms of removing the mechatronic assembly and valves, but I’d be working on a driveway outside - and I reckon it’s likely to be something deeper in the box in light of the age and mileage of the car?

(Or am I being defeatist?!).



Can you recommend a gearbox specialist in the UK? Much obliged!
