According to RAVE the 1995 Classic has two circuits for the front calipers. The correct bleed sequence is complex (like the P38), but not all of it can be done with pressure bleed kit.
The dash LED only show the alarm is set. Sounds like you need door latch microswitches changing.
Does the car does unlock & lock on the FOB ? If not you also need to sort that, or you will wear out replacement latch as well !!
The Nanocom numbers also change in real time, but not in photos !! RH blend pot or motor definitely not correct.
Best way to see is to unplug from HEVAC, and put a ohmmeter across the pot wires. Then move them with a 9V battery & see if the ohms reading changes correctly. Short pieces of...
Are you 100% sure the pot is not reaching it's end stop ? The pots & bought recently also need the gear in a non-standard position. Also check the distribution gears are correctly aligned - there are little marks on them as well.
How free are the flap gears ? Even stickyness at one poiunt...
Never tried it because I don't have a diesel, but in EDC settings there's an option to edit & write the setting.
BUT wait for the experts before changing anything.
Rail pressure = 0 ?? Engine speed = 0 RPM ? Sureley the HP pump needs the engine turning ?
Do the same diagnostic reading with the engine cranking on fully charged battery (or jump cables). Then see if the rail pressure looks better ?
Both are 1998. Yes one of them has an extra ignition switched relay to remove power to the EAS timer relay & ECU with ignition off. did it to block self-leveling.
Will try the hold button on the other when I get a min or three.
Yes, and it reads correctly in Nanocom.
Seems to depend a bit on the temperature. In winter they tend to settle an inch or two. In warmer weather they rise at the back !
Tried the hold button today. Started at home, hold button engaged & selected motorway height. Then drove to Sainsbury...
Doesn't work on either of my P38. I did try it several times, but next startup, both always revert to normal height. Maybe the ECU is different on yours ?
What you mentioned about C257 Pin-6 being bypassed to C177 could well be why the BECM does not send the code to the GEMS. The BECM does not know you are starting the car, so never sends any signal !!
I did a bacis (non scientific) check on the bench with my Son's VCU when we changed the prop UJ, and VCU bearings. Just clmped one side in the vice, and then use a big crowbar to check the VCU would turn & not siezed or sloppy.
Then put some white paint marks on it & re-installed. Seems to...
But even with replacement BECM, GEMS, etc. the wiring still needs sorting. To be honest, unless the BECM has been messed with, sort the wiring locks & fob first. Then program a good GEMS to it, and it should all work.
