Depending on where the pressure is read from , the low or high side. Didn’t realise the D3 air con compressor didnt have a clutch.Quote:

The sensor on the D3 is a high side sensor. If you're not seeing at least 5 bar on a day like today (in Perth anyway) regardless of the hour then there's a problem.Quote:

Yes but. With rare exception systems that hold 500kg don’t have multiple o-ring/clamp seals on the pipe work and an open drive compressor with a rotating mechanical seal (at least these days). Vehicles are a harsh environment and the pipe work seals are robust but subject to failure. Particularly anything Ford had anything to do with. Couple that with 525g of gas and there’s bugger all reserve. 2kg of R12 lasted a lot longer with a small leak.Quote:

Ahh yes, I know all about the HPFP and fuel rail sensor.. purchased a new sensor which threw even more faults after being installed, so a HPFP plus a LPFP later installed the original sensor out of frustration and the car ran fine again.Quote:

Gap indicated 3.6psi and theres also a B1B78-84 System pressure -Bus signal/message failure - signal is below allowable range fault logged in the ventilation systemQuote:

Working through getting the correct discs for the rear and decided to also replace the park brake shoes. Quote from the dealer just shy of $500. Bendix shoes from Supercheap $68. I not always cheap, but in this case I know which way I’m going.
It also seems that following the Bodsy Brake routine leaves the park brake shoes just slightly skimming the disc based on the wear on the inside of my discs which is quite pronounced. I then took a look at the workshop manual and it specifies to back the pads off further than the Bible says which might explain that. It also explains to me why it needs annual adjustment given the drag and pad/disc wear. And no, I don’t use drive off mode and use my park brake each time.
For the park brake I don't see why you wouldn't use the cheap version. All it has to do is keep the car stationary and doesn't really do any "braking" as such. When I burnt out my LHS rear pads due to the EPB locking up I got my shoes, rotors and pads from Rovacraft in Bassendean and from memory they supplied RDA partsQuote:
