curlykevs Posted March 3, 2017 Author Share Posted March 3, 2017 hi i changed the suspension air bag and now i get this message from vagcom Quote Link to comment Share on other sites More sharing options...
Bigdave1230 Posted March 4, 2017 Share Posted March 4, 2017 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. Quote Link to comment Share on other sites More sharing options...

Bigdave1230 Posted March 6, 2017 Share Posted March 6, 2017 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 Quote Link to comment Share on other sites More sharing options...

Bigdave1230 Posted March 6, 2017 Share Posted March 6, 2017 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? Quote Link to comment Share on other sites More sharing options...

Bigdave1230 Posted March 6, 2017 Share Posted March 6, 2017 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.

Bigdave1230 Posted March 6, 2017 Share Posted March 6, 2017 Is it a genuine cable you are using to program. If you do vcds options test what does it say. Quote Link to comment Share on other sites More sharing options...

Bigdave1230 Posted March 9, 2017 Share Posted March 9, 2017 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 Quote Link to comment Share on other sites More sharing options...
