Well fitted a new seat module, easy enough job with just 4 bolts and lean the seat back enough.

Looks like a dealer job?

Well managed to get the module coded and it’s not fixed the problem so need help, Topix would help or a tec at Lear that can change the frame, it’s so complicated and buried in the seat.
Warranty doesn’t want to know.

The massage seat doesn’t work and the seat frame with the motor and valve needs changing.
So it’s seat out and strip and re build.

Weekend job to change the massage unit, just picked it up, over £600!
So I had Topix access and it’s hard to use when you have no idea.
I need to remove the head rest and rear screen and the speaker grill so I can get the cover off, looks a mission.
Any help with info.
I plan on making a video, must be very common as this part was stock at the dealer.

Well seat came out easy enough with two people and it came in the house for strip down, couldn’t get the head rest out so gave up there and it’s not a problem.
Came apart well and some bags were still inflated.
5 hours later it’s back in the car, had a minor issue with closing the tailgate with the battery disconnected!
12 volt battery under the bonnet on the jump terminal fixed that.
Not tried it yet as it’s just back in, still have the screen to re fit.

All back together and working properly,
£620 for the massage frame £450 for the module, £100 coding and free labour, resulting in massive saving from Land Rover quote of £2500.
