**update 04/03/20**
Well I got the car back and the yellow suspension light was on solid. I called Neeldub round who has VCDS and we did a scan clear all the fault codes and did a basic calibration. it seems to have cleared the yellow suspension light. Strangely lift mode is sometimes greyed out and then comes back on again.. Anyone know why this might be? |

Does the lift mode grey out when the car is standing still? It does grey out at a certain speed but shouldn't do at stand still

I'm just glad after 3 weeks, I've got the car back. There are still some issues that need sorting but I hope to do that soon. I can here the compressor running, I think the garage have not mounted it correctly and the damn thing vibrates quite a lot. I've ordered a new fitting kit and hope that does the trick. |

Morning all,
Right, I've driven the car this weekend and found that if I'm in dynamic mode and drive above 20mph all the other suspension options grey out. When the car slows down to below 20mph all the other suspension options illuminate and become selectable again. I can also hear the compressor cycling a time to time, I'm not sure if the mechanic has mounted the compressor incorrectly and it is fouling something. I know it is mounted on a special insulating kit - perhaps he's done something wrong here. Any idea chaps? |

Reading through the previous posts, is it possible to get it scanned again to see if you're still getting the over temperature code, as I'm wondering if this is why the other options are greying out, and that although the compressor is giving you the 16 bar output, maybe there is still another leak somewhere. Finally, others including Neil suggested getting the fuse and relay replaced. Do you know if this was ever done for definite, as it's standard practice to replace both when replacing the compressor, irrespective of their condition, and it's not the hardest job to do... just lift up the passenger footwell carpet, remove a piece of moulded polystyrene and replace them.

Steamship, thanks for the insightful response.
I've had all the error codes cleared, Neel and I did a basic 're calibration and it seems to have cleared any warning lights on the dash. I don't think there is a leak as I've put the car in lift and Jack mode and left it for 36hrs and did not see any drop. I can select all suspension options below 20mph. They work fine when selected. However, once the car exceeds 20mph the suspension options grey out. We did an output test on the compressor and I'm sure it wasn't 16bar. I think it was 10 or 11 bar. So I'm guessing this compressor isn't great, I bought a used one to get me going again. I'm guessing this is now the issue. I also understand the garage replaced the relay however, I may buy a new one regardless to rule that out too. |

Regarding the compressor, I was going by one of your previous comments about testing it, unless it was just a typo.

Steamship, Architex - thanks for the replies again
I think it is something to do with the selected speed at which it greys out has been altered. Once the car drops below 20mph all the suspension options are selectable. I can select them fine and they work. The car doesn't throw up any error codes. On a side note, it's quite a complex system the air suspension and it does pay dividends to understand the system well. I found out that the diesel A8's and the petrol A8's have different compressors. I've manged to source a compressor of a much later A8 petrol with the following part number 4E0616005H. I will rebuild this one and it should cure the slightly low output I have with my (tired) replacement. I've had to get much more involved with the repair than I anticipated but there is some light at the end of the tunnel. I'll report back once I have done some more work on the car. |
