HI ALL. YELLOW SUSP WARNING LIGHT ON WITH NORMAL SUSP HEIGHT ONLY WARNING. CHECKED DTC`S USING LAUNCH & CAME UP WITH CODES; C1A34 REAR RIGHT CORNER VALVE & C1A38 REAR CROSS LINK VALVE. ANY IDEAS MUCH APPRECIATED. ALAN

Hmm.. Ideas..

C1A3401 - Right Rear Corner Valve
C1A3801 Rear Cross-Link Valve

In addition to general electric failure, causes can be:

a. Rear valve block disconnected
b. Rear valve block harness wiring short circuit to ground or high resistance
c. Right-hand rear corner valve failure/Rear cross-link valve failure
d. Air suspension control module failure

You would need to refer to the guided diagnostic routine for these codes on the approved diagnostic system.

Got exactly the same fault (no idea about codes though) on my 2006 sport today, Yellow warning light and Normal Suspension height warning in the message centre, only 2000 KM's from home at the moment

Audi Mechanic, are you moonlighting on a RRS

well it had one new Compressor fitted today, all is well for now, covered under the allianz extended warranty. Apparently it is near impossible to get hold of LR stock, so after markets are being fitted on those out of manufacturers warranty, most probably better quality than LR original parts after the shonky experience i have had with LR build quality over the last 4 years

Mine was the 3rd Sport booked in this week with a compressor problem, 2 MY06 and 1 MY08 (poor sod has been lumbered with waiting for genuine parts and referred to their LR dealer not specialist company i use), wondering how big a problem the Compressors really are ... bigger than they will admit i bet.. Another Pommie Bar Steward down under

If you don't know already, in addition to the compressor being replaced it is required that the air suspension control
software is updated at the same time to ensure correct operation of the air suspension system.  Malaysia Boleh!

Cheers Bobby, will talk to the specialist tomorrow to see if they are aware, they are doing these on a regular basis they tell me, even those like BKHK's that never get off the tarmac

Any detail on the code or revision for the Air Suspension Control Software Another Pommie Bar Steward down under

my 2009 RRS 2.7 is at the dealer as we speak due to suspension failure error. I just got the message that the air compressor is faulty and it will be replaced under warranty.
The car is 16 months old with 30000km and I wonder if that happened now what I can expect in the future.

It's nice that LR gives 3 years warranty but it looks not enough. 2009 Range Rover Sport 2.7 TDV6 SE, Alaska White, Almond leather, tinted windows, active rear diff, tow pack, HiICE, full spare: gone and already missed
