Please, I need help! I am DESPERATE! I've read most of the threads on the suspension issue, but I have yet to find one that addresses the exact problem I am facing.

We own a 2007 Land Rover LR3 with ~112,000 miles. We noticed a slight suspension issue (possibly not fully inflating during normal operating height) and then within days the dashboard warning light intermittently registered yellow. This light then went permanent and the suspension system fully deflated. The result was a “low rider” look and quite a bouncy ride. The system would warn of a suspension fault and say that “Normal Ride Height Only”.

I live in northwestern Montana and the nearest Range Rover dealership is 230 miles and 4.0 hours away in Spokane, Washington. I called their service department several times, left voicemail, and have not have my calls or messages returned. So, I am unwillingly trying to figure and resolve the issue with my local mechanic.

We ran a diagnostic on the vehicle using a Snap On computer testing unit and received a fault code of C1A27 (compressor circuit). We then bypassed the computer and applied power directly to the compressor which would not run and we assumed it was a bad compressor. After researching the options, we purchased a new compressor from Messier Automotive USA (Air Suspension Specialists) that will supposedly be the right replacement for our year, make, and model. The new compressor arrived and I was excited to get our beloved Rover back up and running.

With no formal installation instructions included in the part, our mechanic installed the new compressor, relay switch and air hose (all included) and we cleared the fault codes. We were wrong when we assumed this would be the end of the issue. We can turn on the ignition and no error lights turn on, but as soon as we try to activate the suspension (to fill it or actually set it on normal height), the system faults and the same fault code appears of C1A27. We checked and there are no blown fuses in the engine bay next to the battery. We attempted to temporarily bypass the system and provide power to the compressor which does run, but does NOT fill the system.

We just don’t have any idea what is wrong and we can’t seem to get any help from Range Rover. Please advise!

Given your statement that the repair kit included a piece of hose, I suspect that you replaced the pump with one that requires a software update.

There are two solutions to this issue that I know of.

1: Replace the compressor with one of the same style that will run with the current software revision.
2: Find someone with a Snap-On Pass-Through-Plus and have them download the correct Vehicle Configuration File (VCF) and burn it to your EAS ECU.

That is probably what is happening to my 07 lr3. I replaced the desiccant and the seals and is still getting the fault. So I called Botzons Auto in the Spokane Valley 1-509-928-4747, they work and is certified on all European autos and have vast knowledge of Land Rovers, told them the issue and I have a appt for this Wednesday for the diagnostic. I think that the fault codes need to be cleared because the compressor works then shuts off.

We will see then. I would call them and verify. And you are right, The Land Rover dealership here is still rebuilding its maintenance staff. Good luck getting your rover running again.

Hello all, the problem with my LR3 was that the compressor was going bad. It was only putting out about 150psi when its supposed to be 250 psi. Botzons auto diagnosed it and I had it replaced a few days later. So the moral to this story is that sometimes its not the common problem. Bye the bye, the compressor was covered under the extended warranty that my wife insisted we buy when we brought the car. This worked out because I did not have to get cold and dirty, nor buy the part. So consider getting the extended warranty for all of you new rover owners.
