Thread: D3 Air Suspension Compressor Failure

Hi Tote,

That was great. How many k's on the the D3 when it failed? I use access height quite a bit as I have a petite (see might read this) wife. So the compressor gets a reasonable work out.

Sorry, meant to put the vehicle details in the first post. Vehicle is a Jan 2008 build and has 125000KM on it. Compressor warnings started at about 112K.When the faults first started occuring the compressor blew the fuse and failed hard. The dealer tried replacing it and the fault was still there, they traced that problem to a dirty connector and did the firmware upgrades. The compressor then worked OK for about a month before the current problem.
It developed to the point where it would fail regularly at about 120K (just as we were leaving to go on holidays). Failure mode was that if you started the vehicle the suspension warning light would illuminate after about 2 minutes and you would get a "normal height only" warning on the display. If you used the height control before the failure message it would take anywhere from 30 min - 4 hours for the failure to occur. So we could still use the air suspension on holidays.


I also use my air suspension quite extensively as every time I go to work I drop the vehicle to fit in the carpark and I always raise it in other car parks to minimise door dents. I could have grumbled about the time it took to diagnose and the cost of the compressor failing just after warranty expiration but at the end of the day I'd rather have a new compressor anyway.
The dealer (Lennock in Canberra) has been excellent with their service but they are governed in their fault finding techniques by the strategy laid out by Land Rover. It is easy to say that the valve was the cause of all my woes but I'm not sure that it's 100% to blame as I think the original duty cycle of the compressor with the previous firmware may have contributed to excessive wear.

Regards,
Tote

78k for me

From memory, mine went at about 120-130,000km

Thanks Tote. My MY07 has 118K km now I have had it a year and its a great bus. We don't have a dealer in town which worries me a little if I have a complex problem. The closest is 150km away.
By changing the duty cycle do you mean it is running for a shorter period?

The software upgrade sounds like the one to reduce the reservoir pressure, presumably to incease compressor life. However that upgrade in its various forms was for ALL D3/D4/RRS/FFRR Terrain-Response air suspension vehicles from 2005 onwards so replacing the compressor without having the update applied was not going to cause failure any sooner than the original compressor.

In the absence of a spare compressor, those repair kits might be good to have as spares on a remote area trip for those people who don't mind getting their hands dirty or even for someone else to fit.

there is a prob with this if been out west and it stops, the light will come on for a 100 different resins, so just dont asum that when the light comes on its the compressor, all so there is about 6-7 codes relating to the compressor failing, only 3 of them will be 'fixed' buy fitting the dryer kit,

all so there is diffrent soft were for the ride control as that spring all so has a diffrent tention to the first compressors, and that there is a new set of level sensors for the airbags,

not that this complicate things

Can you recall when that compressor build date commenced ?
