Air suspension - is it bad? Which models?

Hiya, snuck over here from the Disco section Been looking at a few Range Rover TDi's for sale but don't know much about them. Is there a problem with the air suspension? I don't know anything about it, unreliable/expensive? Did all models have it?
Cheers folks

More to the point, them diesels is sloooow!

Can't really comment on all models of RR as mine's a P38. The EAS is fairly robust but as these cars are aging there are a lot of failures and chain-reactions you'll read about here. No way around the fact that the system is more complicated than it needs to be (that's LR for you). Dealing with some kind or air suspension problem in the course of your ownership is almost guaranteed but keeping a cool mind and working through logically will usually get you through with only moderate amounts of profanity...

P38 EAS is good if looked after IMHO. The diesel is not slow if chipped.

Like you I was wary of the P38 for a while. I tried to find a nice Classic instead, but the Classics that aren't complete rotboxes were too expensive.

So I researched the P38 and I found the EAS software by RSW, bought a lead and a really cheap Toughbook laptop. This laptop can also run the OBD software by Alex Peper in the USA I use for my Fords; I just need the ISO lead to read my Rangey's diagnostics.

I've had my 4.0 SE for three months now and there is just nothing else like it. Just driving it is a special occasion every time you get in. If you're thinking of doing it then do; I had a landy years ago but the P38 is just something else!

Cheers for input. So which models or years had the air suspension? Sorry, I know nowt about RRs, dunno what a P38 is!

basically a p38 is a mkii range rover,the smooth one usually wiv lots of toys + a lot of electronics which can cause a lot of fustration,you can cure most things cheaply you have to think outside the box!!!!!!!(so im learning),i have no end of niggles with mine but it allways goes,its smooooth and addictive,its very different especially when your a spanner ,hammer and feeler gauge man.........dave

Ta Dave, just read about your woes...you haven't been knocking down monkeys have yer? So what year did the P38 turn up in?

All P38s have air suspension. There is a fundimental flaw with it. People use and forget it, in other words don't maintain it. That's about it. You need four good sensors, a good compressor, NO leaks and it will last virtually forever.
