Ahhhhh.... there is a page visible in Nanocom "Security" pages that tells you whether your BeCM is LOCKED or UNLOCKED. By all means go look at it but whatever you do, do NOT try to change that setting. If it says your BeCM is "Locked" then you...

Moot apparently. If you can’t listen to advice it’s impossible to help you. We are all repeating ourselves. Plenty of advice in the searchbar or JLR maindealer. Good luck.

Generally a diaphragm failure causes problems with the system not filling the tank. My guess is it's probably ok. Also if the NRV cones have any wear, find the best one and use that for NRV-1. The other two only impact operation if the...

Take the seat out, take the lid off the BECM and check for condensation. With the seat out, you can check all connectors. There is no indication from what you say that the BECM is locked out but of course I could be wrong. You need to look...

Not to nanocom Willy nilly Everything from post #2 onwards 😂 Avoiding the issue is not the same as resolving it. It’s your call.

I'd get the key/s sorted first before writing the becm off. You need a functioning key either way and then go from there👍

Make it think you need to take it off.

You also need to check that the cone shaped nose on the NRV's are smooth with no indented ridge.

I'll have to buy some more O rings then! Bubbles at the dryer were only seen when the compressor was running. Once it went off there were none. Even with it running they were very small bubbles, small enough to make a foam around the top...

Tank leak will usually be NRV-1. With the system off, air leaking through NRV-1 will pass through the dryer, and lift the diaphragm, hence inflating the balloon (path of least resistance). Some of this air can also escape via the dryer seals &...

It'll depend on how well it's tuned👍

If the car is an auto, it will in due course knacker the gearbox as effectively nullifies the torque reduction required on gear shifts to protect the clutches. Plenty of ooomph in the M51 if it's running well IMO.

Get it running as best as it can, before even thinking about wasting that sort of money ...

A great man once said “fitting a tuning box to an already unhealthy engine is as useful as tits on a mars bar”. He said that to me. And he was right. As usual If you wanna go down that route look up p38 PSI or Synergy box but unless your...

Cross thread it, nature's loctite.

There are 3 NRV's. If one is bad, best do all 3 IMO. More likely to be the diaphragm I would think. A new dryer is not that expensive.

My mate has a couple of disco 6x4s or 6x6s, can't remember which. They do look cool and would make wicked compact campers.

Balloon over the exhaust will tell you if the NRV and/or the diaphragm are leaking Have you checked for white powder in the exhaust?

Loctite the bugger in🤔

Pull the exhaust filter from the block and put your finger over it. Make sure a door is open so the system is isolated. Hold your finger for a while and monitor any air loss👍

Change the earth strap then you have a know good one as they rot where you can not see they are a common fault, located passenger side engine mount area.

Try a jump lead from the negative battery post to engine and supply a direct earth. If you can have the starter checked over to rule it out. 🤔

Good old mechanical unimog👌

Oooohhhhh I'd love to have something like that. Always been a fan on non-mainstream.

Yes you should put the ignition to off for comms with becm. It doesn’t work with ignition on.

Low battery volts causes all sorts of problems. Put a fully charged high capacity battery on it and see what you have.

This mourning i went for a walk and sw a vehicle that i havnt heard of for sometime and thought some people might be intrested in .It was in camper form and looks the buisness for serious off road travel. Its an OKA and built in Australia...

Nah it rained 😁

Youve washed it 😱

Don't know and going away on holiday first thing in morning s can't check til I come back. I don't like driving with tyres that aren't right. have had 1 blow on motorway and that was once too many
