Air supension overhaul

[ulfilias]

Hi there,

Have a few faults with the air suspension, so i've set about overhauling it!

First thing was the compressor!

But mine is quite different (A8 PF 4.2 Sport). It's in roughly the same place, but it's rotated 90 degrees to this and in the lower section. I have a two pairs of 3 blue plastic air pods there. I found popping the fog light grill off and some judicious use of socket extension bars I could get it out without needing to part remove the bumper, though handy to have a second pair of hands ocasionally, particularly when putting it back together.

To refurb the compressor. It's £25 delivered and seems a good kit, though i've yet to fully test and my cyclinder did have a little scoring so I will have to see how it lasts.

Next to have a look at the Valve as I have an intermitent error on that (same wheel arch, other side)

I recently bought the Bagpiping Andy kit and had my compressor overhauled as a precautionary thing whilst the wheel arch liner was being replaced. Well worth doing if your mileage is over 100K

Hi There,

Mines done 130ish

It's all back together and so far no errors. In playing with vagcom and running the compressor up, it sounds a lot healthier and builds up preasure a lot lot quicker. I was able to go through the 4 wheel measuring alignment thingy and then also sort out the headlights which seemed somewhat reliant on the leveling.

I can select Lift when starting the car which I couldn't before. I also found that the compressor is purely electrical and can be run with the engine off. I did have a power line hooked up whilst testing so not to flatten the battery

Ta,
Lee
