Audi Repair Questions? Ask a Mechanic for Answers ASAP
My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
From what you have described here this sounds like the instrument cluster itself is at fault.I have seen shorts and in some cases even voltage surges cause failure of the instrument cluster as well as other electronic control units.In this case it looks like your instrument cluster was damaged internally electronically needing either removed and repaired or replaced.The CAN communication lines and the telematics and Nav functions all run through the instrument cluster electronics.
You can try and reset it by locating and removing the fuses that feed voltage to the cluster for about 5 minutes then reinstall them and see if this works but I suspect it will need repaired or replaced.I had one case where battery arced and it had damaged 8 control units/ecu's and they had to be replaced so unfortunately with the electronics in these anymore any short like this tends to damage the control units.This sounds isolated to your instrument cluster here.
If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.Thanks Pete.
If your VCDC says your going 158 the roof will not operate in fear of damaging the top if it thinks your at this speed.Most all newer models are set up to where the top will only operate in park or at a very low speed usually less then 5 m.p.h.
I don't show a complete diagram on this myself but here is what I do have so you can check signals.This does sound like the cluster is causing this needing repaired or replaced.

I apologize for the delay as I was off line this last weekend.
The signals look to come from the Central control module.This control module is tied into the roof operation as well as the cluster operation.Since you do have all lights and functions on the cluster when you do the testing with the scan tool and they do operate properly the central control module is most likely at fault and isn't controlling these components properly on the instrument cluster or allowing the roof to operate properly.
This does sound like a fault with the central electric control module.
This looks to be under the drivers side door sill area as seen as #10 below.And #2 in the second link.It will need coded/programmed by a dealer or authorized repair center before it will operate properly after it is replaced.
You are correct and I apologize for that.When I punched in the central control module that's what was brought up for some reason and I didn't look at it to well but looking at my info on it that is the wrong one.My info unfortunately isn't showing me a location for the central control module but it should be located under the dash board area.A little early for me still I guess I need more coffee.I apologize for that.
Terminal 15 is an ignition circuit missing usually.Did you double check to see if any fuses are blown at all since the replacement?
O.k.,let me know if you find any issues.
My info and from what I have gathered doesn't tell me this needs to be replaced with a new one and a used one should be able to be used and programmed to your model.
If you can test the voltage signals to the control module and see if you are missing any voltage signals.
Unfortunately my info is not showing any diagrams on these here.Above I did post the info on the terminals in the connector for the instrument cluster to check for power and ground issues but my info isn't showing me this or any diagrams for the central control module.If you want i can open your question up for others here to see if anyone else can assist further just let me know if this is something you would like to do.
