Hi All

I am New hear and looking for some help with the following codes.

Audi A4 Cabriolet 2003 Diesel 2.5 TDi V6

My Father has a Registered Vag-Com and has managed to pull up the following.
But he is not a Mechanic and therefore the info stops at that..lol

I have fault codes as follows.
01315
18055
18265
18033
They all seem to relate to the following.
Malfunction Indicator Light (MIL) ON or Active
Engine control unit / Transmission.
Any Ideas on a fix or more info would be a great help.
Thank You
Katy
