Hi Rob, can't see the photo. Are you sure it isn't the transfer box? There are a couple of well known potential leaky points on those. The gearbox on mine is the one thing that has never leaked

I just added the photo, sorry. The drop hangs where the red circle is

I have exactly the same drip of oil in the exactly the same place, golden drip, lowest point of the transfer box housing. Any oil which either weeps out of the seals, inspection hatch cover will tend to gather at this point. I had a major oil leak dripping through there when the front drive output seal went, but that was frequent coin sized drips on my parking place. The inspection hatch can weep through the sealant and occasionally benefits from a bit a gentle tighten. When you refitted the drain plug last time, did you use a thread sealant like plumbers tape for instance? As oil can sometimes pass the drain plug.
Hope this helps, as usual you could just wash the transfer box drive down the A5 for a bit then stick it back on the ramp. I always considered the golden drip reasonably normal due to seals weeping oil due to thermal cycles. I'm sure somebody will be along in a bit with another theory

It is very much likely to be gearbox or transfer box oil. It almost always runs to this lowest point. You need to source the leak, follow the trail of wet oil to find it or, as said above, clean it all off really good then go for a drive and put it straight on a ramp. If you're lucky you'll see it trickling.
One quick check you can make is the adaptor shaft housing (aka Gearbox Extension Housing) which sits between gearbox and transfer box. There is a small drain hole on the bottom of this, stick your finger or blue paper towel on it and see if it's wet - if it is then it's likely to be the gearbox output shaft seal and / or transfer box input seal. Both require removal of the transfer box. Often when this leaks the air as you drive along blows the oil back and it hits the transfer box casing, then running down to the place you pictured. It can lead people to look in the wrong place. Thanks  Now: 2010 2.4 TDCi 110 Utility Wagon

I had about the same problem. Took it to an experienced garagist. His answer was not to search/repair it. There is a big chance it is more leaking after the repair.
One drop is not leaking, it is “sweating”! Kris |

It is Landrover's unique oil level monitoring system, as perfected over many years with the Series vehicles.
When the drip stops, it is time to check the oil  |
