MMI, some bad, some good

[tc4332]

First the bad news.
SWMBO is once again rather vociferous and sad.
MMI has started clicking and failing to open correctly.
Management is claiming that she cannot drive the car 'cos when she is within ten metres of the car the Parking Aid refuses to work and with no MMI panel the reversing camera is useless.

Now the good news.
I phoned the dealer I bought the car from and his reply was "No problem, I'll send you a set of gears in the post. No charge". We have had the car for over two years so I think that is very good of him. Means he will be my first port of call if I ever manage to buy another car.

Having done a bit of research it looks possible to do on the house front drive.

Any pointers/watchouts from folk that have done this?
