Had my Audi A3 2.0 tdi SE 2004 for a couple of weeks now, while driving on the motorway I have noticed that when I drive at 70 in the first lane it feels like I am going slower?
Lots of cars over take me and I never seem to overtake anyone.
I could even do 80 and it was very similar. This got me thinking that the speedo could be out?
Last night I decided to plug the sat nav in to see what speed that gave me. I while doing 80mph on the speedo the satnav showed I was doing 72mph!
Is this normal? Or could I have a fault somewhere?
