Air suspension weaknesses??? Opinions Please :)

[A8L Chick]

I have ordered a new compressor (OEM GULP!) for my D3 A8L, as recently after engine shutdown, something sounding like a tractor was still running (until the battery went flat)

I "think" it sounded like the compressor, and it was coming from the n/s front of the car (you could feel the vibrations) ooh eer from both inside and outside the car.

Now, I am mainly after opinions on what the weakpoints of these air suspension setups are in your opinions? I have just randomly ordered the compressor after the suspension warning light is now solid orange and the suspension is stiffer than the EVO :cry: I feel like I am driving a 1980's ****box now-not an 80k luxury sedan

I hope after ordering that it is the compressor burnt out, and not anything else, but if it isn't fixed-what do you think I should try?????


(I have had her in for guided fault finding-but after 1 hour Audi wanted to do a further 3 hours fault finding to diagnose the fault................. at over £100 an hour they got told to go jump )

Do you have access to VCDS?

I have yes, and although I can't remember the exact fault codes, there were 2:

One which stated an electrical fault and the second which stated an air leak. I know through searching the web that these two faults combined can mean the compressor is fried, which would make sense...it sounded literally like a tractor.

Inside the car the MMI has blanked off the LIFT & DYNAMIC settings and only allows Auto or comfort to be selected, although whichever you select, nothing changes in the suspension, no softness in comfort-still feels like a bag of bones.

I hope replacing the compressor is an easy job-because I am going to replace it on my own.

Does anyone know whether it needs configuring with the car???

Many Thanks

Anyone???

Sorry Bex, Looks like your the first with the problem.

Erm.. You could have a leak in the system (other than the compressor) which would increase the work rate of the compressor and potentially the noise (though must admit I can't remember hearing mine).

A8parts should have a D3 compressor floating about as well. Does the whole car sag, or just one corner?

The whole car has gone stiff now, I think you may be right. I have bought a new compressor, when I fit it I will have a look to see if I can find any holes/splits in the hoses etc.

That is what I thought too, and almost hoping for.

Does anyone know whether I have to code the compressor to the car once fitted or will the car recognise it and sort the coding?

(P.S thanks for all input-it is greatly appreciated)

[PsYcHe]

I don't think the compressor has to be coded to the car, so you should be OK.

How much was this part you ordered?

[A8L Chick]

Hi Nathan, I got an OEM audi part for £400.00

Now I just have to work out how to fit the damn thing...?

I took the bumper and headlight out and have no idea how to access this bloody compressor?

I think I may have to remove the bloody wing!!!
