Beginning of the end - Compressor?

[brickpaul65]

I had my first suspension fault followed by a slow raising message on the trail this weekend.

Small background:

My compressor seems to be running longer than it used to upon start up (about 1 minute - essentially level driveway). This weekend on the trail I had a suspension fault and the compressor seemed to be running more often -several times during the course of the hour to 1.5 hour trail.

I have johnson rods installed and I was at offroad height. I don't know if the suspension should run periodically while in use or if I have a small leak (no real suspension lowering is noticeable while parked etc. and the valve blocks are replaced). I may have just noticed the compressor during this trail run because it is running longer instead of the small intermittent burst I was accustomed to / never really noted.

This is the second compressor (2006 LR3) and it is at least two years old probably 3 years estimating the frequency most forums note on the original compressor. It is not the newer AMK compressor.

Does this seem to be the compressor death spiral or potentially something else. Are the compressor failures pretty quick start to finish or do I have time to get the part and plan on the repair as opposed to getting it done fairly asap (1 to 2 months).

Thanks,

Paul

The new compressor is a major improvement and failure rate is almost nil according to my dealership.

I have heard the same thing. I am definitely going that route when needed. I just wanted to see if now is that time or if my symptoms could likely be another issue. I believe what I experienced is pretty much what people describe for the initial compressor failure. I want to get all of the life I can out of this one without being stranded . I also don't want to fix this and miss another issue.

Also, Dendy, your LR3 looks great!

There is a software update to accompany the new compressor that changes its operating strategy. It is very important to do both at the same time.

Before buying a new compressor, replace the exhaust filter on the compressor and see if that fixes it. I did this on my 06 Range Rover, and it fixed my compressor faults. I also replaced the air dryer while I had the compressor out.

 

[brickpaul65]

Do the exhaust filter and dryer come with a new compressor? If not are those parts compatible with the new compressor design or do I have to buy a different dryer and filter with the AMK version?

I was just going to say the same thing.
And the IIDTool does this update...

My compressor seems to be running longer than it used to upon start up (about 1 minute - essentially level driveway).

The compressor running for one minute on start up is a sign of impending doom? Guess I'm screwed then.

Heck no. Mine (2013) runs for about 30 seconds to 1 minute pretty much every morning when I first start the car in the garage, and for several seconds here and there throughout the day, especially after the engine starts.

My 05 is the same, and it's been like that the two years I've owned it.

have you tried the classic 'leave it parked at full height with a door ajar' so see if it leaks down overnight? A lot of the time a failed compressor can be a result of other air suspension components leaking, thus making it work harder/longer than designed for.

 

[brickpaul65]

I had the leakage earlier this year and I replaced the valve blocks, that seemed to fix that issue. The longer run times just started recently. It always ran a little bit. I timed it, about a minute. Now it can run for two minutes on start up. The real worry for me is it now raises slower and runs for a looooong time after raising. While on the trail last weekend I received a suspension fault and restarted the car. Later on the trail I received a vehicle raising slowly message. That is why I think I am starting to have issues. Are the dryer and filter included with the new compressor assembly? If not are they compatible so that if I replace them and then need the compressor next year or that does not solve the issue, I don't have to purchase different ones for the new compressor?

Thanks for the input guys.

If the system is tight then time to replace the compressor - or do that coil spring swap.

I hung in there for years with the bags on my p38 - both stock and the Arnotts. Finally gave up and switched to coils in a motel parking lot in Moab after yet another bag failure!
