New to me. Bought from a friend. Dilemma. Two unrelated issues, related because they were worked on by same independent local 4x4 shop here in durham.
1. Ac compressor replaced 500 miles ago for $1k. Blowing hot air now. Independent says there’s a leak. Put dye and leak fix(!) in and told me to come back. Complaint number 1 - why did I spend 1k on compressor when there’s a leak somewhere. I think that could/should have been caught when he pulled a vacuum but maybe not.
2. The eas compressor was replaced in dec 2018 by same independent with Arnott compressor about 3,000 miles ago. The ‘normal ride height’ error came up on the dash and I realised there was a leak somewhere because I could hear it hissing after I parked. I bought a gap iid tool and messed around with the suspension and stupidly bottomed it out by releasing all the air. I was scheduled to talk to shop about leak and error message and I took it in to have a look. I told the independent that it had been holding at the right height for about 2 weeks prior to that morning when I had released the air messing around with the gap iid. He lifted it in the air and came back to tell me that I had a bad leak in the front airbags and would need both struts replaced at $1700. On top of that, because there was a leak on the airbags, he would not warranty the 3,000 mile old compressor. So add another $1000 for a new compressor.
I told him again that the air had been holding great for the last 2 weeks that the Error message had been showing and the suspension had been inactive and that it was only out of air because I let it out that morning. He absolutely wouldn’t warranty the compressor.
So I went home and jacked up all 4 corners. I had it in the air and somehow, I really don’t know how, the compressor started to pump. So now I could hear the hissing again and I determined to track it down. It was a pin hole in the tank on the passenger side running underneath the running board. I let the pressure drop and sanded around the hole, jbwelded a small piece of shaped galvanized and closed up the hole (temporarily). It fixed that leak fine and I lowered the car and it filled with air and was driving absolutely fine. Holding air, compressor working great and drove around another couple of weeks. Then an hdc fault came up and then the normal ride height again. Now when I start up, I can hear 3 digital attempts to call the compressor (at the compressor, 3 high pitched sounds), the compressor doesn’t start and the suspension error message comes up.
My dilemma is, do I take it back to the shop. I feel like they misdiagnosed the problem and that maybe they should reconsider making good on the warranty on the compressor? The leak in the tank only lasted about a week (that I could hear) and I would have thought the compressor wouldn’t be over taxed by that?
Anyway I’ve got to get it fixed. I’ve attached the gap iid fault report. If anyone has had similar issues, please lend a hand. My first ever car was a county 110, blue with a full length roof rack and a rear ladder. With the rover 3.5 liter petrol engine. That thing was great and pretty simple. This rr is not and I’m having trouble pinpointing the problem.

Thanks, I may do. As far as the eas is concerned, I’m hoping I might be able to fix it myself if it’s a height sensor, weak battery (12.2v cold), or perhaps compressor. The ac I can’t fix myself for sure.

They have performed two major fixes for me thus far and have been dead on resolving the issue and warning lights the very first time.

One thing I really appreciate is instead of sending me off to the dealer for a VIN coded ABS pump, they used the controller off of mine and swapped it to a donor part. 1/3 the price of new.

They’re very resourceful.

Experiencing multiple error codes at the 91982 mile mark suggests that you also have an underlying battery issue, too.

It would be worth having a local auto parts store load test your existing battery.

Regarding the HVAC; a leak in the system allows moisture to enter, which ultimately could have compromised the original compressor. Not a certainty but certainly a possibility.

Where is the leaking dye suggesting the leak is located in the HVAC system?

Thank you for the responses. That’s good to know about euro motors. Not too far at all. I’m disappointed at fhis shop because just like the dealer, all they wanted to do was throw a new part at the most obvious issue without discovering the underlying cause. And to be so emphatic about not warrantying the eas, again without getting to the bottom of it. I bought the car with 99,000 miles and the eas compressor was put in at 89,000 miles. Unfortunately Arnott warranty is non transferable. The shop could do it but Arnott won’t send one out to me without the shop being on my side.
Anvilrob, I haven’t been back to the shop to se where the leak is in the ac system. May be a job for euro motors.
Thanks again.
Does anyone see an issue from the codes I’ve sent pointing towards the eas compressor failing or something else downstream? If it were a height sensor, how does the code, or the gap tool help tell me which corner to check/replace?
And is it possible to test the eas compressor operation by jumpering the Exum under the drivers seat? I’ve seen that referrers to with the markII but don’t remember seeing it for this model.

And to be clear, I bought it with 90,000 miles on it

I'm not a trained Range Rover expert by no means.
By the codes and there definition. I would have the Battery tested / replaced if bad. A weak battery may work fine for cranking, but does not supply enough voltage to retain learned memory of the modules when cranking. Most of those codes sound like untrained modules, or a communication problem. I would relearn all the trainable modules. I'm sure someone here can tell you how to do that, If it can be retrained without a diagnostic computer. Also check all the fuses. As for the air tank you repaired, replace it. That can be dangerous. Hope this helps and good luck.

There is a small device in your A/C probably under your dash/clove box. It diverts your cooling and heating. I can't think of the name of the part off hand. It is cheap and not easy to get at and replace. BUT can be done by anyone with a few tools. Same thing with your compressor. I bet it is full of water(removing humidity from the air around this area) so change the dryer more often. once every 2 years unless you use up and down lots, then once a year. Add a new battery or at least check yours (13.5 volts DC) if all the other codes keep coming up!

Lots of problems with compressors, RR switched to Hitachi make with new software. Airbags last 5 to 10 years depending on the environment you run your car in the other issues I had one time, RR installed new compressor and it was not set up right and on start up it blew both front air bags. Next was the splitter block adjacent to the compressor also renewed
There is also a height sensor RHF wheel check it's not damaged
