Hi Kev...welcome to the Forum

Sounds like a leak in the air suspension

Here is a link to some available parts http://www.audiownersclub.com/parts-results/Q7/Air-Suspension--Parts/174088

Let us know what you find

Cheers  Trevor

hi i changed the suspension air bag and now i get this message from vagcom

[Bigdave1230]

Sounds like a valve stuck open. If the bag had such a big leak that it goes down straight away when the pump stops then I doubt it would lift it up in the first place. The over temp fault is just because the pump keeps kicking in. Unless it's really noisy it should be fine. There is a valve block just behind the pump that might be stuck but check the individual valve on the strut first with soapy water to see where the air is escaping. What have you changed to get vagcom to say that. Have you changed the bag and now it's stuck down on the corner and won't raise the car at all? If so jack the car up on that wheel to take some weight off and see if it will raise it up.

i now keep getting invalid when i do put in measurement in channel 4 all others channels ok but channel 4 invalid and then channel 5 says error 

[Bigdave1230]

Channel 4 is the rear right I think and 5 is just to confirm the values so probably will say error if there isn't any value in 4. Have you entered anything for 1,2,3? What value are you entering in channel 4. Is any of the suspension lower than the rest. I think the test conditions are that the engine has to be running and all the doors are closed

hi yes set height for 123 but 4 says invalid  so cant set 5 drivers side lower than right side 

[Bigdave1230]

Is it Left Hand Drive? Is just one corner down or both on that side. What is the value you are trying to enter? Is the mmi greyed out on the suspension settings? What parts have you changed on the car to get to this stage?

hi it is right hand drive it is higher on passenger side 123 set ok 4 wont take it is at 410 i have tried taking it up 20mm says invalid so tried 15 still same tried 10 still same mmi is on automatic only no other settings changed front bag it is now better but cant set untill i get channel 4 sorted

[Bigdave1230]

Hi what are the levels for all four channels and what are the stored values for all four channels? I think if the stored value for example is 495 and the actual value is 410 then the ecu won't allow such a dramatic change and so you will need to set it to within 20 of the stored value until you can get to where it is.

got all 4 channels valid and tested and saved channel 5 tested and save but every time it says no response from controller so will only on automatic all others greyed out

Is it a genuine cable you are using to program. If you do vcds options test what does it say.

yes genuine cable vcds now getting channel 4 invalid so now cant set 5 

[Bigdave1230]

What does vcds - options - test say. You can ring Rosstec for support who will talk you through some things to see why it's not talking but to be honest I'd probably ring Audi and pay £80 or something to get them to do it on there computer if it's gone on this long. I've only seen something like the problem your having when my mate bought a Mickey Mouse lead from eBay when his original one broke
