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...
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.
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...
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.
Yeah I’ve seen this mentioned before. If you can let me know that would be grand - if not I’ll trial and error disconnecting them and see what effect it has on the readings.
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...
Finally got around to ordering a Nanocom. ABS and TC lights have returned, so 2 front sensors have already been replaced - be interesting to see if they’re the culprits again. See what happens and maybe order a full set.
Also need to try and...
You’ll likely drop a few MPG - yes they’ve got a larger diameter so distance covered per rotation will be greater.. but they’ll weigh more. More mass, more energy required to rotate.

This can be quite a good site to see size differences and speed changes. Most speedos over read your actual speed, so indicated 60mph could be actually be 57mph for instance. Provided you don’t go too far bigger...
The P38 has been retired from daily duties to now being a weekend only car. It’s thanked me by throwing a constant ABS/TC fault, so need to get the Nanocom on that..
But today has certainly highlighted the need for me to fix the air con. There’s...
