Thanks for that info Gilbert!
I can just picture you in the Cat detector van looking for Tiddles!
Good fun alright!

Being a Ham, I used to love "Fox and Hound" Transmitter hunts! Ahhh the many misspent nights of my youth!
And to think, YOU got paid for it!

Got the new valve from LK8 and it is in the dreaded Britpart box.....
Had a look at it, and I see now the flaw in the design.
O ring is already squirting out of the gap between the cap and the base casting.
This is a Chinesium pattern part, so even worse!
I will not knowingly trust my safety to CCC pattern parts......So, back it goes!
So, for 12 bucks, I have bought 30 (minimum quantity) of the correct size and formulation O rings
and will just fix the one I have.
I have a couple of photos of the new defective part, and have failed to be able to attach them....
I know there is a trick to it.....Post them somewhere and link to them??
In any event, I will report back if I succeed, also I will be offering the 29 other O rings for the cost of postage.....

I do have 2 keys from a previous p38. This will be a spares car until my neighbours start to moan. Maybe I could disable eka etc on the spares car? Going to depend a lot on the cost of the Welsh key.

You would be well placed to use those keys without any outside help.....
Swap the Becm, Ignition switch, ECU, and drivers door lock from the spares care to your daily driver.
That will get the system working assuming the aforementioned parts are there, and are in working order.

Otherwise, have both Becms unlocked and read. That will tell the specialist what the lock set codes are. They can then input those into the other Becm.
Then get the spare one cloned to your current driver. This way, you end up with working fobs and a spare drop in Becm for your good one! (How cool is that!?)

I have had a few failed attempts to access the HVAC on all of mine as well as a few
locked ones I have helped people with over the years.
I have noticed that if I go to "Faults" first, it will nearly always fail to communicate, but if I go to "Inputs" first, it is fine.

Beg to differ with honorable Gilbert San........
I have had 4 P-38s that were (are) daily drivers and on all of them, I had the Becm's unlocked.
I have never had any issues with either an Nano or Faultmate MSV-2 connecting with any system.
Marty has confirmed that this is not an issue as he has not had any issues either......
He said that he had "heard of it" but never had any first hand reports of issues caused by it being unlocked
I have also failed completely to brick an Becm, but that is actually a real worry if you are not paying attention.....
In any event, it is necessary if you wish to use keys from other P-38s. Again, if you can get the fobs codes read
by someone with the proper scanner.
There are a couple of guys out there with the specialist tools to unlock them. In the UK, NZ, Oz and USA.
As for reading Fobs, only one or 2 that I am aware of, and those have gone a bit quiet lately......

Thanks for the link!
Good read over coffee.
Happy New year!

To add to that addition.......
If you have no key fob, and get one (or a pair of them from the same vehicle), you can have their codes
read and enter this into the (unlocked) Becm......

Thanks for all of the information on this issue.
This will save me trying to "Troubleshoot" the system.
Hadn't come across the aforementioned document, is it part of Rave?
Happy New year!
Tom

Ahhhh..... So that does indeed clear up the issue....It's not an issue, just another interesting "feature"
of these beasties!
Still trying to work out just why you would need to shut off the compressor before activating the valves?

Hi

I've managed to lose key2 from my p38 4.6 thor.

I have a key2 from a p38 4.6 gems, can a nanocom change codes to allow me to use the key2 from my other car?

The working key1 that I have (thor) often reads "engine disabled" until I press a key button. Has new batteries- any other issue I should look at?

Hi Gilbert, sorry I haven't answered on the other forum, I've managed to lock myself out again. Not ignoring you. I will get a internet pc up and running soon, seems that Android doesn't quite cut it over there

You can use a key from another P-38 under certain conditions. The Nano can reprogram the Becm to use a different key. I have done it.
First, the Becm must be unlocked. This alone is a deal breaker for some folks.
Second, you must know the fob's lockset code. There are folks here that are equipped to read this code
if they have the fobs in hand.
If you have a locked Becm like most, it would probably be easier and less expensive to have Les in Wales make
you a new Key 2.
Of course, if you are in the UK, the Stealership will be happy to extract a pound of flesh in exchange for a new fob!
Here in NAS land, we do not have that option.

Whilst perusing the dark side, I found this which is part of a post fron Jos G. from 2012:

"When you brake and the car is stopped, when you take your foot of the brake, the car will self level which cause the compressor to stop running. When the compressor is running and the ecu decides it want to open the solenoids, the compressor will stop to allow this and restart after the leveling procedure is complete."

This would certainly be an explanation for what I have observed. Gilbert touched upon this as well above.
I have not seen this particular behaviour described in print in RAVE or the various primers on the EAS I have seen.
Does the compressor always stop when it does a leveling adjustment?

A slightly late Happy Holly- Daze to one and all!
Just got back from the annual 2500 mile round trip to Southern California to be with family.
No P-38 issues to report, so a VERY MERRY Christmas!
Flicked over to 200,000 Miles in mid trip too!

I had to chuckle about your answer, as RR Toadhall told someone long ago much the same thing.
Said that in all the years he worked in the shop, no one ever had any issues with one.
He was actually shocked to find several instances of reported failures.
On further research, so have you......

Jos Geuze answered the question on O ring size, as he re machined and rebuilt his.
EPDM o-ring (ID is 22mm and 2 mm thick)

I have the replacement coming so not a problem for much longer.
Going to look at the old one with an eye toward refurbishment if I can get the O ring..

It's probably only a common issue on P-38s that have 500k+ miles........

Well, the good news is I finally found the really small leak in my brake system that had me topping up the fluid about every 10,000 miles.
The bad news is that I found it is the PCRV that's bolted onto the fender below the fluid reservoir. The source of the leak became obvious yesterday when it became a larger leak!
Apparently, the design is such that it will slowly extrude the O ring seal inside causing fluid to escape.
Of course, I found this as I am preparing for a 2500 mile trip South for Christmas next week......
The new part is on order, but will probably not arrive in time, so the question is:
Can this be repaired?
Seems like if it has an O ring that has an issue, it can be rebuilt?
Anyone done this? Know what the O ring size is??
Cheers.

I have not checked to be sure, but suspect the pin carrying +12v is on the corner of the field.
The metal shell is, of course B-. The slightest misalignment at the critical instant will have the
case grounded, and that pin in contact thus an "STS" moment (Something touched Something)
The tiny spark is just a courtesy to let you know you need a new fuse!

Good Grief!
"Mr Prosser" is alive and well! :)
The inmates are really running the asylum over there.
Logic is gone and blind faith in flawed data systems are becoming the norm it seems and
"common sense" ....Isn't!

I know it's only a matter of time before this spreads across the ditch.
Be afraid......Be very afraid!

Ahhh,
Well, I am glad I mentioned my trials with it, it seems I am not alone!
Cheers!

Yep!
I discovered this whilst being lazy.
Sitting in drivers seat (LHD) when the Nano would lock up such as switching off engine whilst looking at eas values,
I would unplug the cable from it rather than getting out, walking around and cycling power by unplugging the OBD cable.
it did not seem to matter how carefully I tried to re connect the cable, something would touch something, and I would need a new fuse!
Leaving the cable firmly clamped on is a good policy!!

If you unplug the cable from the side of the Nano, at least for me, it will short the power pin when plugging it back in and blow the fuse almost every time!
Maybe just my bad luck, but I stopped unplugging the cable from the Nano and just do the contortionist act to get the plug in under the dash.
+1 on leak being at the Pollen filters or plenum. It does not take much of a leak and if the filters are wet, it works like a swamp cooler to humidify the incoming air!

I have tried 3 different known to be good relays. Same result.
Will dig into it further today.
I am going to look at pin 8 on the EAS controller to see if the signal comes and goes
