I think that is a very reasonable thought. This is again what we started with in many threads, that the wiring and electrics can be a little suspect.

Simple things usually cause some of the most complex problems to unravel

Dead right, but then simple ideas are usually the best.

So which twit at LR put the main electrical connectors for the suspension behind the (non-sealed) plastic nearsidefront wheel arch liner and expected it to stay uncorroded for any length of time?

Vitch connectors do you refer to?

LR assist bloke that attended when second compressor was going down checked one or more multipugs in the back of the NSF wheelarch behind the plastic arch liner (You need to remove the mud gaurd to pull it forward from behind the wheel arch spat).

He said this was the main feed (presumebly power ?owt else?) for the suspension from the back of the underbonnet fuse box. I think he meant the compressor. he wasn't specific.

Anyway he said it was semi-sealed as it had rubber o-rings in the middle but several had been found to be grubby/slightly corroded because if water gets in it can't get out easily partly due to the o-ring and partly because the connector is mounted on a clip vertically alowing any water ingress to sit in the top of the connector. He had been told to unclip them to allow the water to drain, give them a good clean and spray them with something that smelt to me like it would lift paint.

Anyway only solved my prob for about 5 mins.

Hope this is useful

See what I mean about the twit design engineer @ LR.

He said in his best SS Interrogator accent Wink

How about the exposed connector in the left rear wheel arch behind the flimsy plastic deflector?

OK. Ich verstehe, auf welchen Stecker Sie sich beziehen.

Same design engineer worked on the wheel arch wiring on each corner perhaps.

Bet he was the ugly one so they got him to keep his face out of view under there all day Mr. Green

Never been any good at foreign languages up here in Yorkshire. Translation please

Update:
Compressor is fine 15 bar pressure test, so its not them themselves that are faulty.(Possibly)

Car back, dealer swapped main susp pressure sensor in sytem on technicals suggestion. No joy. Even the dealer / technical @ LR at a loss

Technicals second suggestion is to swap the suspension ECU. Which my car is going to the regional dealers main site for two days to suss out at the end of next week.

They DO swap the dryer when they swap the compressor. Just for information.

It might not be if the dryer is seperate and not all dealers swap it.

The way I understood it from the conversation I had in the workshop with the tech (who I know on first name terms) is that the dryer is all part of the compressor unit so therefore is swapped out with the compressor by default.

The schematic drawing he gave me this evening also suggests this as it shows the compressor/dryer/motor 2xtemp sensors (1 each for the pump and its motor) pressure relief and exhaust valve, and pilot exhaust valve all as one assembly.

Having studied the schematic for a while and stopping to think my money is still on a reciever problem as there is no drain its sealed completely, or its control valve as this is seperate, or obviously the ECU control of it.

This is for my current problem of slow lift of the susp and the new compressor overheating.
