Gents: (Are there any women on here?)

I have a long-standing suspension issue and before I burn thru another compressor, I'm wondering if someone can help me decifer some codes. I've already don't the research, but i have SO many codes that I'm unsure if I have one issue or several.

Symptoms:
Air Compressor seems to work pretty hard... cycles in the AM before I leave. (goes on an off). Car most certainly is lowering overnight but not on bump stops.

When I get going on highway speeds, it seems I have few issues.

It is when I drive slow or get in traffic that my suspension fault will come on.

I clearly have a leak or a bad compressor, but I don't really know where to start.

After owning this car for 7 years (202,000 miles), I just purchased the icar soft diagnostic tool. TOTALLY earned my money back within 5 minutes of owning it.

Here are codes:

C1A72 - Front Left Height Sensor Mechanism
C1131 - Air Supply
CA1A03 - Front Left Height Sensor
C1A07 - Cross Articulation
C1130 - Air Spring Air Supply
C112F - Air Spring Valve
C1130 - A ir Spring Air Supply (for a second time).

so... where do I start? get a new front height sensor?


Thanks, Gents. Appreciate the help. I would REALLY like to learn how to repair this air suspension...after all this time. Getting tired of taking it to my local guy, even though he's reasonable...

 

How many compressors in 202000 miles, I would look at that sensor or clear codes and see what returns Look at wireing, plugs

 

LR6 or LR3?

Have you tried "Drive Car to airport. Park it for 5 days. Go on business Trip. Return, and it should be gone" trick?

Sorry, just a fan of your past posts. 200k miles? Wow!.... Original alternator?

 

Sounds like a bad calibration, for starters.

 

Don't hold me to it but I'm pretty sure I'm on compressor 3 or 4. I think the last time he did something with the drier.

KMET - I think you're heckling me - and that's cool. And yes - still driving the LR6.
Wait until you see the Air Bag Video I posted on Youtube. 9 minutes of life you'll never be able to get back.

In a turn of events, I just purchased a slightly enjoyed Range Rover from Prestige... and so my LR3 sat for 4 days... this morning it's almost on the bump stops.

Guess I need to get under there with some soapy water....

 

Sounds like a bad height sensor, I would replace the front left, and re-calibrate. See how it goes from there. It is normal for the compressor to kick on briefly at start up. It is part of the start up procedure but it should only be for a few seconds, any longer and it is a leak.

 

Sounds like a leaking air spring. For starters, Clear the faults and find the leak. You can put the vehicle in extended height and disconnect the battery. This will prevent the air suspension module from making adjustments. Do this a night and check in the am. In the am, the vehicle should be leaning towards the leaking air spring. Fix the leak before addressing any height sensors or calibration adjustments

 

Or you could just pull F26E, no need to disconnect battery.

 

ok. Thanks for the advise. I cleared the fault and thus far the only one that's returned is the Front Left Height Sensor Code.

Do I have any options to install this on my own? Not sure diagnostic tool has the ability yo calibrate anything.

 

You can install on your own and may not need a calibration. However, sometimes they do. So no leaks overnight?
