lowering every time puts a lot of unnecessary stress on the compressor. When you think about lowering vents air out of the four bladders. When you raise back up you use all the air in the reservoir. this in turn requires the compress to top off all four bladders and fill the reservoir.

Moving your post and this response as it is off topic.

Additional info. If you have received a hard fault once, it is likely you will again. The 30MPH max warning is pretty serious. It means that your compressor is weak and has been over worked. The EAS completely shuts itself down to prevent further damage.

At eight years old, how many miles are on your rig and are the front struts original? EAS bladders leak at the point of most use. For most folks that is where the bladder rolls between normal and highway mode. You may have increased cracking beyond the normal/highway range. If you are going to do leak checks with soapy water, start by parking with front tyres on ramps if you or a buddy have them. and lower to access mode. saturate the front bladders with soapy water. not only look for bubbles but listen for them.

Just as a labour saving measure, rear air bags rarely fail unless there has been damage from a road hazard.

At 110K miles you are most likely on your original struts from the factory... that's pretty dang good! The only thing I would be concerned with is the compressor. There are rebuild kits available, but if that kind of work makes you nervous, there are new units available from Suncore Industries for about $260. They are out of Florida so shipping should be fairly quick.

Now for front struts I would bypass Arnott products. Thankfully they no longer "rebuild" struts. They are producing new struts for L322s but the are having issues with the collets at the top leaking... and from an ORing situation. It is the actual fitting leaking. There is company in the UK with very competitive pricing that several members have used, exchange rate is favourable and shipping is quick... Apologies I don;t remember who it is but they do come up in EAS threads on a regular basis.

Hopefully someone will hop on and advise

Again, thanks everybody including Burcin. All this help is appreciated. Of course it generates more questions.
1. Many parts websites offer struts (or other parts) for the L322 but if I look further, do they apply to a 5 L Supercharged Rover. Like Island 4X4 says their struts are for L322 with 4.2 L engines. Does the 2011 Supercharged use different struts than other 2011 Rovers?

The question is not in the the engine, the question is if you have adaptive dampening. If you do have adaptive dampening the the struts are the same for 2010- 2012... they are about $1200 State side. If you don't have adaptive dampening then the struts are the same for 2006-2012 no matter which engine you have... They are about $600 State side.

Side note, rear air bags are the same on all L322s from introduction to end of run. They easily out last 2 sets of front struts.
