Hi.
The soft top of my car cannot be open. Audi centre said the error F171 - Roof position malfunction and require full roof removal to replace the harness 8P7972387A. The cost for removing the roof is very high then I need to see if I can remove by myself or any other alternative.
- Anyone has the instructions how to remove-install the roof?
- there is another way I can replace this harness?
- Any other alternative I can do to have available my soft Top.

My car is an A3 cabriolet 2009

Thanks
