I had problems with my parking sensors so I had 2 replaced but we then found out that possibly the PDC control unit (7L0919283D for my Touareg 2004 3.2 V6) is faulty...or it's broken wires which could be worse.

I would like to know if it is difficult to replace this unit and how to do it? I found some photographs of a similar replacements in a Cayenne but nothing too specific.

Thanks
