Hi.I have Audi a6 c7 2.0 2011 diesel. I wonder if anyone had similar issue.My fuel gauge stoped working ( it was playing for some time).I lifted the rear seats and moved cables and connectors but it didn't help. My mechanic said it's gonna be £70 or around £400 depend which sender is faulty( or something like that). Anyone had something similar and resolve it? Don't want to pay £400 just for the part.Have a look at fault code.
