I dug out the thread (here for those interested), and contacted ZF to see if they could offer this on their cars.
Here's the reply I got this morning:
Not only is it a thorough service (and looks to be the same level of work detailed in the thread), but it's also quite a bit cheaper than having the work done at MRC. Also, who else would know these boxes better than the factory themselves (not to take anything away from MRC). So think I'm going to get booked in and head over there - maybe take a detour via the 'Ring on the way back (as I want an excuse to take the '6 over there for a few laps rather than the track toy).ZF Services Dortmund wrote: Hello,
There is a 6 HP-26/28 in your vehicle. ZF recommends to change the oil with 80-120Tkm.
In this case the gearbox oil pan is dismantled and the mechatronic modul is taken out.
After that the oil is blown out of the converter pneumatically. So we can change the main part of the oil.
Sealings and expendable parts including the oil filter are replaced.
The whole procedure takes about 4 hours because the gear must be filled when it’s cold.
We can schedule it for the week starting 16 June
The amount of cost including changing the oil in rear axle differential gear is ca. 540,-€.
Thought I'd put this out there though. No idea if there is anyone else that would be interested in this and maybe I can enquire about two/three cars getting done on the same day.
