What did you do with your Range Rover today

[MrGorsky]

Oh it’s 100% that. I’ve had it regassed and pressure tested and no leaks.. yet it’s not working 2 weeks later. Regassed myself from empty and after 2 weeks no cold air. I need to get some dye in there somehow and try and figure it out - I’m hoping it’s something like the compressor - a second hand unit and a day under the car can hopefully sort it.

I had similar the other week. Tested and no leaks, then two weeks later green dye all over the bottom of my rads.

If it was professionally filled, they should have included dye when they did that. My place said that have to put the dye in these days to comply with the regs. Maybe get a UV light on it tonight in the dark and see what shows up!

This was Halfrauds as it meant they’d come to me. From memory they didn’t put dye in - this was a few years ago now mind.

I'd still have a look about. The guy that did mine said the compressor oil was actually dyed, and UV reflective so if they put oil in (and they should have) then you might be able to see whare it's coming from.

Depends what wabco unit configuration you got. It’s only how nanocom reads it, is actually all right in reality.

Mines wabco D, the last type I believe.
For @P38Seb

Nano said my RR was faulty but twas front left.

Most often it's the top right corner of the condensor leaking.

I've had mine done twice, once at kwikfit, no leaks, lasted a couple of months tops. Then went to a local landy independent who found a leaky condensor(that's common) I replaced that and it lasted about 6 months so I've given up for now.
Ring do a leak detection fluid which can be used everywhere, ac, coolent, engine, gearbox oil. Found a leak that I couldn't see straight away, glows bright white under uv.
Not sure how you would get it into ac though.

This what what Marty posted on the Nanocom forum. As of July 2024 there was no update from BBS.

====================================
Had a look at a couple of P38's with ABS problems, which have both turned out to be the wheel speed sensor. The Nanocom will come up with the fault code of what sensor is faulty, so that's easy enough to troubleshoot/replace...

However, if you go into the Nanocom Inputs window in the WABCO D ABS (I can't comment on the 'C' as I've only looked at Thor vehicles lately!) I've seen that with the dodgy sensor, 3 sensors have shown a proper voltage reading and one (the faulty one) has shown 0.00V.

However the issue is that the one showing the fault isn't the same as the one the fault is logged against. So I did a run around of the vehicle plugging/unplugging each sensor in turn and found that the Nanocom labels are slightly incorrect:

When Front/Right was unplugged, it showed 0.00V on Front/Right sensor
When Front/Left was unplugged, it showed 0.00V on Rear/Right sensor
When Rear/Right was unplugged, it showed 0.00V on Rear/Left sensor
When Rear/Left was unplugged, it showed 0.00V on Front/Left sensor

Is it possible to get this looked into (I guess it just needs the labels changed, or the values moved to line up with the correct labels) for a future software update?

Just to confirm, any fault codes stored in the ABS ECU which relate to a specific sensor are correct - it is only in the inputs where it shows the sensor voltages that they don't line up. I am not sure if this carries over to the wheel speed readings aswell, as the ABS ECU won't give live data above 5mph, so haven't had a chance to test that yet.
====================================

Bear in mind that the nano isn't correct on abs sensor positions.
I've got the correct ones marked on the case I keep the nano in.
I forget which is which and I'm not home at the mo but I'll post them up when I'm back later if you like.

Think that's WABCO D not C and I also have a suspicion they may have fixed it in an update.

Might be the thermostatic expansion valve. If that's faulty it can over pressurise and vent to atmosphere. I got one from some aircon place and it took about 10 minutes to fit. Got the garage to empty it, swapped the valve then got them to regas it. Valve is on the bulkhead iirc.

Doesn’t look too bad to get to, and not that expensive. As much as I’d like to nail it first try this is a 24yr old car so replacing everything won’t be such a bad thing.

Later condensors are difficult if not impossible to get hold of new. Mines the later one, earlier ones fit with a simple mod but you'll need a new pump to condenser hose and they are c£160. Island 4x4 sell them.

Cheapest aircon stuff I've found. And the quality seems okay.... I did all new bits (compressor oil, O rings, dryers, expansion valves) for the P38 and the Passat in preparation for Croatia this summer. P38 blew up after a few days due to a split in the aging condenser (and because it's a P38), but the Passat still blows cold!

I did get a new Nissens condenser for mine off a guy on eBay so I went with that though.
