Arnott replacements for 2011 C6/4F A6 allroad

Forewarned is forearmed, so they say ... as my 2011 A6 allroad is just coming up to 120 000km, I have started to give the airbag suspension some thought to what happens when it blows (not if, but when) and how to beat it to the punch.

Has anyone here had any experience with the replacement/re-manufactured Arnotts for C6/4F A6 allroads? I've done a cursory search, but there mainly seems to be information on the C5 replacements from Arnott.

Cheers, all the best for 2023 & beyond
 
agree Alister, they have had a good rap from what I have read.
 
Thanks to both you and Alister, since there seems to be little mention of the "newer" (C6/4F) versions around & whilst I see quite a few of that vintage A6 allroad for sale around the >150-250 000km mark, I've never seen mention of replaced airbag suspension (including struts) ... wondering if people are just being quiet about it or the later version is more reliable/robust that the original C5 version as delivered new.

Cheers, all the best
 
Having had a C5 for 10 years that needed the stupid bags replaced by Audi under warranty multiple times, and then moving to the Arnott ones when it was my cost (which never failed), yep, the OEM had design faults.

I've had a C7 for almost 10 years and it's still going on the original bags, so they are clearly much much better. (The C7 sunroof is a different story... that seems to be the weak point...)

I wanted the Arnott myself, however, they are not supported with the lifetime warranty here in Australia and distributor fees were very high.

Replacement of the x2 rear bags was quoted in excess of 2k AUD.

So I did research and replaced my bags with this brand -

The quality appears to be very good and in a side by side vs the original Continental bags, I felt these were manufactured with more "finesse".

I replaced both rear bags in my C7 and so far so good - about 20k kms in.

Thanks Wudka, just on the importation, were there any problems buying o/s and getting them here? As I've started getting the occasional suspension weirdness (compressor running more regularly & noisily, front right dropping 2cm in 24hrs), I suspect my time is coming, so a looking at importing all the relevant parts (compressor, bags, struts, valve block, sensors) and getting my "normal" DE-alike garage (Audi/BMW/Mercedes/Skoda/VW) to do the installation.

I never took a lot of interest in the adjustable suspension (former multiple Citroen owner here ... lol) just left it at whatever the previous owner had set it at when I picked the car up, which I think was Automatic, although he seemed to have fun running it up and down (nothing else to do in his 30 min peak hour traffic jams for an ostensibly 5 minute commute) and said that the valve block/distributor had been replaced at about 50 000km (I bought the car at 80 000km). I think the first time I looked at the MMI air suspension settings was last week when I noticed the compressor running.

Any info on how your parts are going would be appreciated, cheers.

Big apologies.
I haven’t checked in and didn’t see your question.

I’ve done over 50k now on them and no problems whatsoever (knock on wood).

I do play between sports and comfort a lot and I do raise the vehicle multiple times a week to off-road when I’m on a job site.
Just in case.

They really did look the part when I unboxed. They looked like quality items and inspection found them to be good.

The courier fee was higher than the parts themselves, but other than that no issues.

I would purchase from them again if I needed to.
 
Cheers, & just to say thanks Wudka, in middle of 80hr trip back to AU, will write more when I get back Tuesday.

Sorry to hear of your gearbox drama, sounds like a major problem that in theory, would be easily solved. Encouraging to hear you resolved it.

Also encouraging to hear your rear Miessler airbags are still going strong.

I'm going to try to organise a trip up to my "local" DE-alike service centre 150km away in the next week or so to check what is required for my suspension weirdness as the green (mostly) and yellow (rarely) lights suspension are becoming more regular and the compressor is running more regularly, then order up a new compressor (including valve block et cetera), right & left front struts and although from your account, the cost of shipping sounds like a horror.

I'm guessing all up, it's probably going to be cheaper than getting Audi to do it. The big problem will come trying to get it done before it gives out completely ... the DE-alike service centre used to be able take a booking a week in advance, now they're talking booking a month ahead ...

Hey,

Yeah, I am relieved that thus far it looks like I have located the fault and fixed it.
I still need to replace the solenoid valve and re-work the arrangement of that wiring harness including making provision for it to not allow the buildup of water at the base of the plug.

Does your vehicle drop in height? When left overnight?
Mine used to drop on one wheel only and when it got bad, it would error during drive and not maintain height, so I replaced both bags within that week. I initially thought it might be a leaky valve.

Never had a return of that issue after replacing the bags.

The replacement is not hard to do, if you have even basic mech skills. Audi wouldn't lock in a price when I called them, other than to tell me I was looking at a few thousand in bags alone. If I had a hoist, it would have been 30mins a side worst case. What they charge cannot be justified.

I get what you're saying about replacing the rear airbags, relatively simple, although the front is more of a problem, even if I had all the relevant gear (last car I worked on was my Citroën CX 2500 Familiale back in the late 1990s-early 2000s, got rid of all tools when I sold it). Now, especially with everything being electronically controlled, it's way out of my league (the Citroën suspension was easy, the green spheres were easy access in your face like the proverbial and a slightly more sophisticated version of oil filter wrench was all that was required to remove and replace).

I've not checked the drop on the front right recently, but some months ago I noticed front driver's side was down ≈2cm over 24hrs. However, when checking the alleged "correct" distance between underside of the guard and centre of the wheel, they were all exactly the same 395mm height (they're meant to be 388mm front and 380mm rear). I re-calibrated it with VCDS and they "seem" to be ok, however, as mentioned, the lights come on from time to time, mainly the green, but then go out again when it regains equilibrium (or whatever it's doing), it's really just the more frequent running of the compressor that concerns me, so a possible leak from "somewhere".

Now, it may be, since I can never recall seeing the green or yellow suspension lights before the re-calibration, that putting the correct values into the system has allowed them to work correctly for the first time since I've owned the car, but the compressor feels like is on its way out anyway.

Regardless, I'll try to get the DE-alike service centre to have a look sooner rather than later & let me know what their thoughts are so I can import the required parts from Miessler (I think minimum will be the compressor & valve block kit), but I'm bracing myself for the front air spring dampers/struts too (all up, ≈30kg shipping weight).
