no coils you may as well have bought a Freelander if you do that , the whole concept of the P38 was built around the EAS system.
But in my opinion it is a compete waste of time and money refurbing the dryer. Its cheaper to buy a new one that will give you 100% clean moisture free and dirt free air that is crucial to the EAS system.
The red O-rings in the kits are not high grade O-rings . They harden after about 4 months of use and in some cases are slightly oversize causing another leak path.
The compressor seal kits are ok as long as you do not damage the piston seal on replacement.
All this will be a waste of time , money and effort if the motor itself on the pump is knackered or the thermal trip is on the way out.
The valve block kits are ok but once again the O-rings are cheap and if you have problems with the base rubber of the solenoids being worn then you will still have a leak.
I would attack one job at a time and definitely get the Dunlop air springs for now so that you can kind of guarantee that they are ok. Spending too much on gen this and gen that air springs is pointless mate if the rest of the system is not running right - in my opinion.
+1.
I'd steer clear of Arnott 2. They used to be about the same ride as Dunlop but last longer but the new design is a bit hit and miss. Gen 3 are definitely an upgrade but boy, do you pay for it. Again, the new connectors are a bit of a faff if ever they need to come out. Dunlop best on price for the ride and will last 7 years.
