Probably been mentioned before but serious enough to say it again.
The pan gasket on my E63 MCT gearbox failed 6,000 miles after a gearbox service & had it not been for the fact that it was in the air at EMP for exhaust work I would never of known as the drips when stationary were almost zero however the underside and pan were wet with oil.
It would appear that it only leaks when hot and under load & I have no idea how long it has been leaking but the main dealer who did the service is redoing it FOC under the 2yrs parts & labour rule and currently I have a courtesy car.
I would suggest that its checked annually at your MOT and that you get underneath and look, failing that get a telescopic inspection mirror with led from ebay or a selfie stick & use your smart phone. If it is leaking DO NOT try and tighten the aluminium screws as they are a one shot use and you risk snapping them or stripping the gearbox threads.
The Tech I spoke to said that these gearbox's have to have the correct level of oil at all times and if it runs low then you risk damaging the box , more so if you track you car.
Remember this could go completely unchecked if you passed the 31k mark as typically merc say that you only service these box's once at this mileage and then never touch them again. Mine will be done every 30K
