Hi new to forum and just wanted to say thanks for hosting.
I had a problem with my new (well new to me) A3 1.6.
Speedo was not working and fuel guage was reading incorrect level.
Searched all over the web and finally came up with the answer from this forum.
Just for anyone else looking here is a link to a how to guide for MkIV Golf which explains a simple check to do before replacing any parts the cause being a broken wire.
