Air suspension advice needed
Arnott Bentley Parts Timeline
So after two years, you revive a old thread saying it’s some confusion? My question to you would be what year did your company start making the new strut design? When I redid my struts last year I never came across any Arnott Design new struts when I was looking to source them so I went with Aerosus. From my understanding the old struts you offered use some type of resistor to have the car “think” it had the OEM parts.
Here is Arnott's Timeline of Products:
- Arnott released remanufactured OE struts for Bentley in 2013-2014 (2019 MSRP $962 + $200 core charge) It was hard to find cores back then and we were in a constant state of backorder on them.
- While we can recharge and replace some worn internal damping components for many Mercedes and Land Rover applications we are currently not able to economically do this for Audi A8 / Bentley core parts. Yet.
- We have not run into anyone else who is even recharging Mercedes / Rover cores let alone Audi/Bentley cores.
- We do replace and renew everything else with Tier 1 components including seals, crimp rings, bump stop, air line fitting and of course the ConitTech air sleeve.
- The automotive aftermarket parts industry agrees with us and sells / lists ours as "remanufactured"
- The Arnott designed new passive front struts were first introduced in 2016 (2019 MSRP $1,169 - No Core Charge)
- In 2019 we released the passive front struts with Eibach dampers (2019 Retail $1,299 - No Core Charge)
- Passive rear air struts are coming soon and will include Eibach dampers

@Johnny : I have the brand new Arnott on my White one and so far 3k miles without any issue... I hope it last at least 5 years...
for the riding : because I didn't drive it at 300km/h... most of the times is less than 150km.h.. and my feeling is it like ORiginal shock on the Black one...
it did change the air spring damper if u switch between Comfort and Sport.. the car feeling Tight...
I heard there are a new one call Bilstein.. do u ever try it? lot more expensive than Arnott and only 2 year warranty..

The only thing I haven't been able to find online is the torque specs for the various suspension bolts that need to be undone. Any help in that regard would be greatly appreciated if anyone has service manuals. The videos I've found online don't mention torque specs unfortunately.

I almost ordered the Bilsteins for my father's 2013 Flying Spur Speed but ended up going the RMT route (though I've now heard some less than desirable things). I too am curious if the Bilsteins are worth the additional money.

Air suspension issues are resolved on my Bentley.
I replaced both front struts with rebuilt parts from RMT in Pompano beach, FL. I chose these for 2 reasons.
1. They knew there were different calibrations in shock absorbers for different year Continentals.
2. Price. They were a little more than half the price of Arnott or Aerosus.
Service, good, parts look good, and, best of all, they seem to work just fine.
I appreciate all the help forum members have given me with my Bentley.

So I have a 2010 super sports with 7500 miles on it to date. The front suspension drops at the same time and same rate. I tested suspension using Johnny's test i.e. put into jack mode, measure ride height from floor to fender and measure again 24 hours after. Front dropped 1/2 on each side exactly. both rears went up 1/8.
Any ideas or thoughts? I do have to get the car in the air and check the distribution block in the rear for leaks.

Hello Bob,
Can you tell us if both sides are dropping together, or is it one side then the other, as it is unlikely that both airsprings failed at the exact same time, also, PLEASE get on this immediately, as the next item to fail will be the very costly air compressor located under the vehicle in the spare tire circle, it will also overload and then fuse the air compressors relay contacts together causing the compressor to run non stop, and hopefully blow the 40 amp fuse, also the compressor has a temperature sensor and if it reaches set point then the compressor will shut down and the leak will allow the vehicle to fall, so when the vehicle reaches lower level and compressor is to hot and valve box activates to let air in, it actually lets air out of both front when it is trying to raise one, SO you need to do the soapy water test at the air distribution valve block located on the air compressor under the rear of the vehicle, also spray soapy water at each airline connection on each strut, ALSO spray the strut themselves at the top and bottom, there is a air pressure reserve tank with a purple air line located in the drivers rear wheel well, BUT if that were leaking, I believe that both the front and rear would have a problem lifting, just a note, it may appear that both sides are dropping together when that may not be the case, so park the vehicle on level ground and put the air suspension in lift/jack mode and shut down the vehicle, next take a tape measure or yard stick and keep an eye on each side, you should see then the failing airspring, line, or connection.
Now if in fact you have a leaking airspring, and again this is just my opinion, I myself would NOT use arnotts NEW design that REMOVES the electromagnetic control valve in their struts, nor would I ever replace just one strut with their non active unit while leaving the other OEM Bentley strut on the other side as a member on here has stated they have done, it makes no sense to me as to the members thinking, for instants, the factory OEM struts have electromagnetic control valves built in as to maintain the dampening of said strut as to which ride mode is selected, comfort or sport, it is NOT just the airspring that sets the ride as some think..... NOR would I use arnotts "remanufactured" units as they are just re-built, meaning they only fix the failing item, mainly the airspring, when it come to the strut itself, as it is a two piece item as the airspring slides off of the strut, they as stated in replies on this site state that they test the strut, and if it passes, they clean and paint it, that IS all they do, they do NOT remanufacture or rebuild the strut itself, and YOU will have NO idea how many miles are on their so called "remanufactured" strut, as they do not know either, you could receive one with 10,000 miles, or 180,000 miles, or more, who knows, I know that if my 05 A8L W12 with 180,000 at the moment were to blow an airspring and I sent it in as a core it would be used to make a complete "remanufactured" unit as the strut itself is in working order and not a sign of any seepage or leakage, BUT someone would end up with my 180,000 + mile strut, with who knows how much life left to it, YES arnott has a lifetime guarantee, But I do not feel like doing the job over and over as some have experienced on AW....
Now, although I have not had to replace any struts on my Audi A8L W12 nor My Bentley GT (still in progress of rebuilding
), I do always search my options for when needed, and I found and called this company to verify that their 100% new strut/airspring units in fact do have all items and functions as OEM, and the answer received is a yes, "100% as OEM" and "includes the electromagnetic control valve in each strut for you Bentley or Audi", and at $1663.00 a pair and free shipping, it looks and sound great !
