2.5 ton paperweight??

On earlier Wabco-C, the live data only works at slow speeds. I think the limit is 5mph, but it could be 5kph ? Not got one, but I heard Wabco-D gives live data at higher speeds.

OK boys & girls, not managed to do much lately as the quite large garden I have was great 40 years ago, but a big PITA nowadays as I approach 80, so guess where my attention has been this last couple of weeks!!
However, I have noticed a couple of observations since fitting the 'new' fuse box.
I get in the car, it starts instantly, then sometimes whilst running, all the doors lock, then a second later, they unlock!!

I unlock the car, but the boot button doesn't work at all, lock then unlock again & it does!!??
The push button has been stripped & is like new.

I completely rebuilt the compressor & valve block, & either the front right or other times both front suspension
would lower within a day or so, now with the new fuse box, it stays up all the time!!??
I HAVE found a leak, I inserted a pressure gauge in the main output from the valve block to the tank, 10 - 12 min to
about 145psi or so, the car goes up & down very quick, but then overnight the gauge drops to zero.
I have not as yet investigated further, am I right in thinking that this airline runs straight to the air tank?
Next job is to spray soap solution around the tank fittings, if no leak found I'll try & run a temp air line & see what happens.
Any thoughts?

Doors locking & unlocking is probably latch microswitch issues. Same applies for boot button not working as it needs drivers door latch working.

Block to tank leak is more likely the gauge or fittings !! Tank air leak is usually NRV-1 not seating properly, but could also be the seal on either end of the airline. To leak elsewhere within the block requires both Inlet & Exhaust to be leaky at the same time.

Also rust pin holes in the tank are possible.

+1 on the door latches. Had the same on mine, replaced door latch/actuator and problem solved. I do believe the MGF had the same door latch and far cheaper than the same one from JLR
