I didn't do a coil spring conversion.

Very hard to say if it's right for you.

I think if I had to pay someone else to swap the struts / springs, I would do the coil conversion. I'm willing to do the work myself, so buying Arnott once and getting free replacements as needed seems to work okay.

It is best to test the air springs for leakage regularly, though; leakage never gets better and will fail catastrophically sooner or later. If you don't stay on top of leaky springs, the air pump will fail from overwork and will push moisture into the valve block after overloading its internal dessicant. Then the valve block will fail.

I think if you fix the height sensors in place and cap the spring air lines at the valve block, you should be more or less okay. If the system wants to lower the vehicle at highway speeds, I don't know how you'd get around that, though.

Hi, just read about your GL spring conversion on the thread. I have a 2008 ML that I’ve owned for 5 years & replaced all the air suspension parts over time, some DIY, some using mechanics. Unfortunately it’s having more problems now. Last time it failed I thought ‘wish I’d changed to coil springs when I bought it!’ So I’m seriously considering doing it now, as I am sick of throwing money at it for the same issues. It’s like it’s Achilles Heel.

Just wanted to ask your experience if you don’t mind.
- I think I saw that you kept the original front strut out of the air suspension assembly, and just swapped the spring from air to coil. Is this correct?
- the rears are air spring out, coil spring in?
- did you solve the error message on the dash (you said a sensor may’ve been unplugged?)
- and lastly what brand springs did you use? (sorry if I missed that from the thread)

Hope you don’t mind me asking all this. Many thanks from Yorkshire, England.
