- With the number of sensors on this vehicle, Range owners unite to troubleshoot and identify the easiest fix for a variety of common issues. Today, I have one for you. For months, my 2014 RRS 5.0L SC has been showing a "Suspension Fault" randomly but I was able to circumvent by driving slowly while lowering into "Access Mode", other times it would mysteriously not indicate at all when I started up or drove. Lowering while driving at low speeds is obviously not a long term fix but the fact that it wouldn't indicate regularly didn't make it a major issue for me.......yet....so I was ok with it. Luckily it only forced me into "Extended Mode" a few times acting like there was an obstalce so the majority of time it kept me in "Normal Height" so that was good news. I could keep driving regularly and it wouldn't ask me to shut the engine off for safety or anything like that but I had no control over height when I wanted it. Isn't that one of the cool features of being a Range owner?? So over the past month, every time I started the engine I would get that dreaded chime and dash indicator, showing, something wasn't working correctly, you know what I'm talking about. I think the goal of every Range owner is to hope and pray you can keep all those engine light/faults off the main screen! My assumption was the air suspension exhaust filter was starting to get blocked but progressed to fully blocked leading to the fault at every start up. I had to locate the air suspension compressor that has an exhaust valve filter which I heard can get clogged up over time. Being an almost decade old RRS, I wasn't really surprised to learn that it could be blocked so time to locate it and troubleshoot. It is located at that the rear of the vehicle under the removable cargo area floor board where you find the spare ties so once you remove the spare tire, you will see the protected air suspension compressor housing. After removing about 20 metal clips all the way around the top portion using a flat head screw driver, you locate the compressor and all air lines. You will also see this gold looking microphone thing which is the air compression filter. Whenever you lower the vehicle in any way, it releases air and that air travels through this filter so you don't hear the hissing. I used a lock wrench to loosen and remove this OEM filter to test if that was the issue. I started the vehicle back up, and after hearing a release of air, there was no longer a chime or on screen fault, heck yea! What I did hear was a constant motor running and when I lowered to "Access Height", I heard a big release of air in the cabin so definitely can't keep the filter off forever as it not only works to keep debris out of the air exhaust system but also dampens/eliminates the air sound as well. The OEM filter is about $20 to $30 USD so not too bad or you can buy an aftermarket version for less. Overall, super easy fix for what could have been a very expensive dealer visit :) Todd is all about helping you avoid that dealer visit which never goes well and always costs you way to much, DIYers win on this one!!
You the man.. just got my 2014 back from shop after 6 months.. had gotten in wreck. Picked up today and had suspension fault that wasn't there when I dropped it off.. how they can give it back to me like that is beyond me but your video saved me.. thanks dan
Thank you for the information I was able to do the same thing and it fixed the problem however that little plastic piece broke off lol so I’m gonna have to buy a whole new suspension filter thing but at least I know it works
have the same truck, great tip, wheres the dam relay? you happen to know? cant find anywhere that tells me....
Great video. Thanks for the time/effort. Have a 2015 Range Rover. Getting default as well. Car keeps going up/down when in park and when idle at a stop sign. Any symptoms at all when your error code was going on?
Good video, thank you for your work!
Whats name of the filter or part number. and where did you get it pls?
Mine is a 16 and it start telling me that so im going to try it out
Thanks in advance
C110C-14 front left damper solenoid problem?Voltage solenoid is 8v the shock absorber was replaced.the error is still present
Great video! Where can I find this filter?
Found mine on ebay for $20, I actually have left it off and I hear nothing so I'll get to replacing it later but it's not needed to diffuse sound.
Thank you sir!
It’s powder from the descant silica beads that are inside the compressor that block the gold silencer. I cleaned mine out with isopropyl alcohol.
Makes sense, thanks for the info. Strangely, I left the silencer off awaiting the replacement but once I covered it back up and reinstalled everything, I don't hear the release, ever without it.
@@toddthom4508 yes once you have the enclosure back together, the spare wheel back in and the truck floor fitted it’s fairly silent as it is. I have read that not everyone gets off as easy as us, some actually have further issue with the suspension.
I had this fault and no heated or cooled driver seat when I bought mine. I was getting a fault code for heated seat module. I unbolted the seat and flipped it back to have a look. For some reason it was unplugged. So plugged it back in and heating and cooling works. So I’ve had two ways fixes so far. The next fix will be a bit more tricky. Someone has forced the cabin recirculation flap up at some point to change the cabin filter. I’m going to have to try and salvage one from a second had HVAC unit and change it.
Did you scan the car? What code came up?
No scan needed, the removal of the clogged air diffuser solved the issue completely so air suspension working great again!
I tried on my Range Rover sport 2016 exact same procedure, because I have the error in the screen “suspension fault or cornering when leaning “ .. but didn’t work, the error was still popping up when turning on the car without the gold filter.. so I guess it’s gonna cost more than that to me 🥲
