HOWEVER, I was surprised (and disappointed ) to notice the DCT lower pan leaking. There is literally no fluid leaking down, just slowly building alongside the seal. I knew this was a common issue - just didn't expect it at such low mileage. Luckily the side gasket is dry as a whistle.
Anyway, I recently replaced the transmission pan & fluid on my F10 550i, so I'm comfortable tackling this. Seems to literally be the same refill procedure (with ISTA). Just curious if anyone here has done this themself and have any tips to offer before I tackle it.

I think age and heat cause these plastic parts to crack and deform..same with the cam box and other parts.
I replaced the sump with an alloy low profile version, plus I have an uprated cam box and an all aluminium water pump in the wings ..
