Dear Experts
It's a 2000 discovery 2. Rear won't raise. New air bags, new sensors, new compressor w/ valves etc. I have nanocom diagnostic reader. It reads no error codes even though dash light is on. It shows only 0.2V to left sensor and the correct 5 to right. When I disconnect plug to sensor it reads 5 V-plug it in goes back to 0.2. Nanocom shows door switches working, but once and only once it showed 'short g' for 'plip signal'. I'm at a loss. Every time I order parts it takes more than a month.
Any ideas?
I read once disco mike encouraging someone not to scrap the sls but ....

It was probably me. I would usually still try and convice you to do it, but it sounds like you've got a lot of money tied up in this, so you might as well try to sort it out. On that note though, I'm sorry I can't help you out. Good luck.

Find a shop that has Rover SLS software,your scanner can't read the SLS codes.

If you are going to be living down there you had better buy yourself a Hawkeye that is built to handle all Disco codes and problem.

I live in remote costa rica. You are my hope.
Seen the 5 V thing before?
Well, I've changed my mind. Based on your situation, I would convert to springs IMMEDIATELY. Seriously. Inexpensive, easy and will never let you down. Figuratively and literally. You can probably find someone on one of the LR forums putting a lift on their Disco and would let you have their old springs.

Thanks but I don't have access to a Hawkeye or springs.
Is anyone experienced with electrical issues? Are there any relays that are suspect? Could a bad connector create a voltage drop like described? And I can't understand why the workshop manual has no wiring diagrams.
I bought this car for my wife to be safe crossing rivers.... It seems Land Rover makes a car rugged enough to get you into remote places but not reliable enough to get you out.
That said, I will find the problem and fix it- any help much appreciated!

Everything is working at the moment! The right sensor has 5.02V(as always) and the left sensor now has 4.85 V. This has happened before. Is there anything I can test when it is working properly?

He's got a nanocom. It will do pretty much everything the hawkeye will do an more.

Did you calibrate after replacing the sensors? Since you don't have access to the rover block like a dealer would, you can just put a floor jack under the trailer hitch and get the height to what it says in Rave and tell nanocom to calibrate the SLS.
