L405 EAS service kit?

Hello everyone,
In the interest of time, I’ll just do a brief intro since I am new to this form. I recently acquired a 2016 L405 SWB supercharged about 2 weeks ago and have jumped head first into ensuring it is up to date on service as well as tackling some preventative maintenance items. I am no stranger to land rovers, I currently have an 1986 D90 and a 1999 P38 4.6hse (still on EAS) which was my former daily driver for many years.

My question:
I have done a significant amount of searching here, as well as other sources online and can’t seem to find any clear information on a service item list, or kit for the EAS on the L405 anywhere. Most posts are just centered around compressor or air strut replacement, however the EAS system is made up of multiple components that should be serviced periodically. On the P38 items like the compressor filter and air dryer are regular items to replace periodically as a service item which helps prevent unpleasant failures of the system, but I’m not finding anything definitive on items that should be replaced for the L405. The only item I found was the compressor exhaust silencer. (I’m aware of the dynamic swaybar system, I’ve already tackled that fluid and filter service). Is there any other items I should be aware of? I noticed the eas valve block on the L405 also appears to be non-serviceable, but replaced as one unit (I don’t mind this considering p38 valve block rebuilds are quite time consuming). Any other advice or insight into preventive maintenance items to look out for is welcome.

Welcome, never seen anything you would call a service item, all manufacturers are now going the "change a complete unit" when a small fault occurs, saves them time and creates a good income...

Having said that, items do seem to last longer these days...

I suppose as the 405 gets older things will fail and enterprising folk will sell individual fixes.... Thumbs Up

Anyway, don't worry, just drive it and enjoy...... Thumbs Up Pete

I fully agree with you on the change from individual service parts to replacement of entire assemblies with modern vehicles. I guess I’m still adjusting to living with the L405, it is definitely less “needy” then the P38.
