Audi Repair Questions? Ask a Mechanic for Answers ASAP
I could understand a noise with the motor- if the bearings are failing. But these digital climate control modules, they set faults all the time for the blend doors. You need to actually clear the faults, and try to adapt the end stops, before you condemn and replace them. A lot of times it is just a sporadic "hiccup". Usually if a blend motor fails it will sit and "tick" as it adjusts.
It sounds like they may not have coded the display panel right when replacing it- which should have been covered in the labor quote, if they did not do it then they should pay to have the dealer do it if they cannot.
"You need to actually clear the faults, and try to adapt the end stops, before you condemn and replace them"
I don't understand this statement (I am not a mechanic) and I haven't replaced anything yet. The first mechanic said they "reset" the faults and that's when I lost AC. They said they couldn't replace the control panel because that had to be done by an Audi dealer. The dealer said nothing about a control panel and didn't seem to understand the need for doing that. They said 2 of the blend doors were bad but recommended replacing all of them because of the labor costs.
So you're saying its the blend doors and it's just a coincidence it went out when the first mechanic ran the diagnostics?
So it can be adjusted without taking out the dashboard and replacing the blend doors? Or is it now "stuck" for good?
The first place didn't say anything about the blend doors but he makes more sense than the first guy.
Thanks for your advice.
