This was a common problem by the first batch of New Defenders, experienced it by myself during testdrive
Problem should have been solved. No Mud flaps for my 90.!

Probably that for the brakes good find Thumbs Up but the 2WD warning light is a concern seems to happen when going over rough uneven road surfaces like potholes.

Just been out for a drive and again no warnings on start of ignition but I drove over the same patch of pot holed road that brought up the warning ⚠️ sign last time and the same warning came up literally seconds after. I then drove home and inspected the vehicle that’s when I noticed something is leaking (see red circle in photo above, blue arrow is front of vehicle) under the car possibly from the the new clutch transfer case that acts like a differential for the new torque on demand AWD system that replaced the central differential on the MY20 vehicles (see below).

Im no mechanic so I haven’t got a clue if this is something major or not but the vehicle as it stands does not work in 4WD or AWD because as soon as the car hits a slightly rough terrain it is triggering the warning sensor to cut power to the front wheels.

Appalled once again. The world would be up in arms if a Toyota LC or Merc G wagon did this.

We just shrug and say “well you did buy a new LR”... 1951 80" S1 2.0

Recalls are never a bad thing ~ if only JLR would embrace them. Instead, they fight them, pretend the issues don't exist and if absolutely necessary issue, quite literally at times, sticking plasters ~ double sided tape, felt pads and tie wraps...

Can you examine that and see if it's water, coolant, oil. What colour is it? Blot it onto some white kitchen towel.

There's been a recent TSB for Velars only with AWD:

SITUATION:
A transmission fluid leak may be seen coming from below the vehicle. There may also be a lack of acceleration and/or a 'juddering' from the vehicle while driving. A transmission warning message may also be displayed on the Instrument Panel Cluster (IPC). Upon further diagnosis, the fluid may be found leaking from the transmission fluid cooler pipes.
CAUSE:
Excessive vibration transmitted through the transmission fluid cooler pipes while the engine is running, causing the weld joints to fracture.
ACTION:
Follow the instructions below.
