Hello all,I have an 08 A4 cabrio 2.0t & I'm kind of confused about the syst check it does. When I start it it shows the oil light followed by the coolant light, in red,then it scans the others then I get a yellow OK. Is all well or do I need to worry, the Manuel says if I get those two in red there's a problem so I'm not quite sure as this is my first Audi. Thanks a lot in advance!
