    My D2 developed air leak in one of the rear bags, 15 minutes later it had a good shot of gorilla snot in it (those Tyre sealant stuff) and was working well for long after that.

    Fixing my trailers broken steel suspension cost me the best part of our traveling day, and the repair only lasted one week.

    It's not always as bad as it looks, but I guess one has to upskill your roadside repair knowledge and tools as tech advance in vehicles.

    This is exactly what I'm saying. So we agree then. More likely to fail. Not gauranteed or even likely to fail

    Ride height sensors, both, on two different occasions.

    Air bag leaks, replaced both when one failed.

    Compressor failure on two vehicles, the D3 due to off-road damage, the D2 due to age.

    I could jipo my way to a workshop on all the failures.

    I don't think that it was bad luck though, according to all the indys I've spoken to, failures from less than 10 years are to be expected.

    Something that I also believe gave the airbags in the D2 a bad rep was the fact that they were never replaced, if I recall correctly those airbags had to be replaced after 5 years, and they were hardly expensive as well, but I am not sure how many D2's ever had this done, so now you have a lot of vehicles on the road with ageing airbags long overdue for replacement, but when one of those bags fail the market blaims the entire air suspension setup.

    What some of the industry has to say:

    "For tractors, air ride suspension became the standard many years ago on over-the road applications, while vocational vehicles often use leaf spring suspension because of their greater durability and capacity" Rob Braswell, technical director of American Trucking Association's Technology & Maintenance Council.

    "little maintenance is required for leaf spring trailers during their first six or seven years. Over 10 years, maintenance costs are 900$ for air ride versus $240 for leaf springs." Xtra Lease.

    "The company tests found that while leaf spring suspension while leaf springs suspensions can last the life of the trailer, air ride suspension are more likely to require replacement and more prone to failure." Steve Duley, vice president of Schneider.

    And surprisingly perhaps one opinion on ride quality:

    Leaf springs actually provided a better ride quality in most circumstances. ... air rides are better when trailers are empty..." Steve Duley.

    I agree. The airbag leaks. It is ignored. Then the compressor overheats trying to keep the bag inflated, replacing the bag would have saved the compressor.

    I replaced mine with Arnott Springs which have a 10 year guarantee.

    Air suspension does normally give you warning before it fails completely.

    It's failure which a steel spring can't have though.

    I had a 1984 One Ten V8. I sold it around 2010. Strange fact that in 26 years the coil spring hadn't broken yet. Very weird. I must just be lucky.

    Interesting point.

    Air suspension almost always gives you warning symptoms.

    Steel suspension seldom does.

    And for people using it InDaBush, a little knowledge, and some simple tools and spares makes it almost fool proof.

    Steel on the other hand, a broken leaf spring or cracked/snapped attachment point, eish.

    And believe it or not, the friendly smooth nature of air bag operation seriously reduces the stress and load on accompanying suspension elements.

    Thats why Land Rover used coils instead of leafs.

    And those D2 airbags were vulnerable, not as in D3 onwards where they were protected inside a thin aluminium flask canister against dirt, grime and stones and the rubber sheive underneath

    High output diesel... Is that the SDV8 in FFRR and RRS?

    No nothing that special. The 2.0 engine delivers either 147kw or 177kw dependent on tune.

    BUT imho the low output would be the better option for something like a defender.

    Exactly the same testing that the D4 and no doubt the D5 went through ... I have an almost identical vid clip of the D4 doing these tests

    Well.. why? A little extra power never killed anyone.

    assuming the same internals and it's just a map, more power = less longevity

    besides, you want low-end torque and ability to cruise at 120kmh, not necessarily at 160kmh.

    I thought the Amarok owners already disproved this school of thought?

    It's just 20% more power that you probably will use like 10% of the time you own the car. If it were to last you 50 years, it will instead last 40. Or if it were to last you 20 years, it will do 18 instead. Numbers aside, I only see this approach by manufacturers as a marketing and product differentiation gimmick. I hardly see longevity of the car being in question here.

    besides, you want low-end torque and ability to cruise at 120kmh, not necessarily at 160kmh.
    How about those very few times you want to overtake 5 trucks at once :-P
