I've got a slight gearbox leak (top of the box - filter needs replacing). My Indy are aware and have checked the fluid level and topped it up a little (was slightly low).
Prior to getting to the Indy i'd seen a little fluid (not oil) on the garage floor. Literally a few drops. Hence getting the car to my Indy to diagnose the gearbox leak.
Before all this I had had a single 'Tiptronic Emergency run' mode alert on the dash (gear selection on dash flashes 2nd and D or similar). This prompted me to check the rear of the car when cold the next day in the garage, and that's when i saw the fluid. Later confirmed as light loss of gearbox oil (some misting over the rear sump area too).
I've now had a few more of these dash alerts (all at low speed) which leads me to think it isn't low fluid related.
The car is in early August to have new front tyres and alignment (both pretty much shot on the inside). Plan was to get these swapped out first in case they are the cause of the Tip warning (inside fronts are WELL below the wear marker).
I suspect that i'll need a new TCU (or conductor plate) - this seems like a common cause of the Tip Emergency Run alerts for a lot of 911 and Boxster Tip owners.
Has anyone had the TCU conductor plate replaced? Is it a pretty straight forward job? The box has to be dropped from my car at some point later in August to replace the leaking filter, so i suspect getting the TCU conductor plate replaced then would make some sense?
I'm pretty sure this is the error my Indy read from the PIWIS: "Speed comparison between n2 and n3 implausible"

This has happened on my older 911 - 52 plate car *possibly* with the older Merc / ZF gearbox? (I forget what year they changed these)
EDIT - http://www.911uk.com/viewtopic.php?t=122035&sid=5e7130f75800889c0ff15b6006bf5f6e additional details on the Tiptronic Control Unit and the conductor plate from this older thread. The conductor plate looks like a viable first part to swap. Part number: 140 270 056 1 Looks to be Merc-based part, around £150. I haven't called OPC yet for their quote
uh:
140-270-116-1 might be a newer replacement part (unclear yet if this is 'better' than the older part number, or just a newer manufacture)
The Merc box on the Porsche is the Z229.6 i believe: (Conductor plate replacement video - https://www.youtube.com/watch?v=ImUYRu-VhCE )
The conductor plates on these can be swapped for replacement units. I don't think that's possible on the later Z229.9 Merc boxes (although i'm pretty sure they aren't used on the 996 Porsches, or later models Porsches for that matter)
Cheers
