Ok, I've been in touch with a garage listed on zf.com.
Told them the symptoms and that so far no error codes.
They want to use 'land rover diagnostics' to read error codes and give me a report.
I thought as a zf specialist they'd be able to do more with zf equipment or is that naive?

The gearbox is ZF but who makes the ECU fitted in the car? Could be special to Landrover/BMW to account for 4WD.

Pretty sure zf make the whole lot. Not sure though
Often its simpler to use vehicle specific diagnostics to read live values, its interpreting those values that skill and experience come into their own.
ZF diagnostics will be 'rolled in' to SDD, its only when the transmission is out and they can interact with components on the fluid test rig that specialist OEM software will be used.

Well it's been to the garage and it's got a ton of gearbox error codes, non of which show up in SDD.
The guy strongly recommends a full flush and valve body/mechatronic clean which is going to be the best part of a grand. Failing that it's a re-con box at around £4k plus fitting costs

Do i need to do some drive cycle to complete them? The last clear would have been 100s of miles ago

Honestly, I couldn't say - it appears to be an unfiltered list of tests, maybe they have some ZF process that initiates the tests, it's certainly not a screen or list I've seen in SDD, some of the DTC's are contradictory so it wouldn't be a plausible list of co-existing faults.

From the logo it's this..
Tool Review: Autologic Diagnostics DrivePro diagnostic platform
A must-have for shops servicing European vehicles, the reviewer says.
Tbh i thought it was supposed to be jlr diagnostic, that's what it says in the invoice
They probably mean diagnostics for JLR vehicles, not SDD. I've used Autologic in the past and they do develop their own test routines, rather than copy & paste from the manufacturers own kit so maybe they have some runtime routines to fully 'exercise' the transmission? Honestly, I think you'd be better off asking the ZF specialist as I'm currently well into guesswork, not something I like doing!

Thanks. I don't mean to put you on the spot but it's always appreciated to hear a different view, even when it's guesswork

I need to ask how historic this data is.. i have just remembered i had a low battery event last year which lit the dash with every fault known.

told.. the low batt would not cause the clutch pack codes and dont know how old they are. but, like has been said, they arent actually error codes, just incomplete tests.. unless thats a quirk of the drivepro autologic.
i'll see if i can figure out how to do a transmission test in SDD

Incomplete tests and conflicting DTC's suggest a comms problem to me, but on an L322 I'm just guessing.
