After doing the chip replacement a while back on my spare HEVAC, got back on the HEVAC in the P38 again today. Replaced the 16-pin connector completely, and then tested all three motors using 9V battery & multimeter. LH Blend pot goes from...

Probably the gasket, or whatever sealant has been used in the past. Looks a bit like where the front cover sealant is supposed to go ?? Put the EAS on maximum height, and place blocks under the bump stops to prevent it dropping. Then just...

+1 ^^^^^^ Release the pressure slowly using a thick towel or rag on the cap.

Careful how you take the cap off the expansion tank because the coolant could boil over.

It's about right for tickover, but you either need working diagnostics, or move the multimeter so you can see it from drivers seat. For your diagnostic issue, check the voltage across Pin-16 (12V) and Pin-4 (Ground). Connector might need...

It would help to know the Low & High pressure readings. Might not be the filter

Took wife's 2005 FL1 for MOT today. Passed with no advisories !!

Did you do the pressure test wiht the engine hot ? If not, get it properly warmed up for a few miles, and then do the pressure check.

You could try the old idea of soaking in bucket of diesel for a week or so ??

If it's only a small amount missing, chances are it's evaporated by the time you look for it !!

Also check that GEMS is set for the correct engine size. 2nd screen in settings menu. Once you get the settings in the right ballpark, you should do some drive cycles to train the ECU.

Also unplugged & tested blend & distrib motors using 9V battery & multimeter on the pots via the 16-pin connector. All seem to be working ok with smooth resistance change through the adjustment. But, when plugged back into the HEVAC, I get...

For info, here's my GEMS at idle. No faults stored, and adaptive not cleared for many months.

Yes, using Nanocom Inputs screen.

That's HEVAC on diagnostics I presume? The display is outside air temperature.

Replaced connector on heater core sensor. Old one was rather corroded where the copper wires were crimped. Now HEVAC says correct remp instead of -8deg !!

Bought her AA breakdown cover. In the vain hope I won't use it this year. 🤣🤣 The RAC called me a couple of days ago to ask me if I would be renewing this year. I wonder if he was surprised at the " hell no!" response 🤣 I decided to see which was...

In that case it's easier. Pin-1 = 12V, Pin-3 = Ground, and Pin-2 is the output to the ECU. The description in RAVE is not quite correct, because the IAT is in the air-filter housing. The attached LR System doc has the correct description on...

Both banks appear to be in Closed-Loop which implies the O2 sensors are working. They should be toggling, so do the voltages for these change ? (FYI, Nanocom is too slow to show the actual switching). Air flow readings say 1.64V and...

There's only one Adaptive Values Reset in Nanocom for either GEMS or Thor. (Can't remember which you have) No option to reset MAF, O2, etc separately because the ECU learns using all of the sensors together. Have you also checked the O2...

There's an option on the Gov MOT History page to check for vehicle recalls.

When I did my P38 4.0 got the Arp Studs from https://www.realsteel.co.uk/ in West Drayton. Was a genuine kit & cheaper than most other suppliers. Price depends if you have 10 or 14 per head.

Check the connector ?? Also check what values you are getting in the Inputs screen, rather than just faults.

@svenology Upload pictures of both the old & new compressors showing the fittings. Then we can see what you have & advise.

Outside handle attaches to green clip. Inside handle attaches to the lever circled in blue. Both of them operate the same metal lever, so the problem is likely to be one of these attachment points. About 6:30 into the video below shows the...

Upload the video to YouTube. Then copy the youtube link, and add here using the Insert Media.

But does EASunlock initialise now ?

Rimmers has lots listed on this page. https://rimmerbros.com/Item--i-GRID009678 Look for your VIN range & note the part number. Then google for that part to find best price !! Most likely for VIN VA350483 onwards is AMR6244...

Depends on the year. Is it a GEMS or Thor ?

Usually best to make sure the compressor & valve block are working before replacing the airbags.
