I'm new to this so please bear with me! I am looking to buy a 330d touring, around 2002-2004 model. I have heard horror stories regarding swirl flaps, egr valves etc and would really appreciate some advice. I do not have a clue when it comes to mechanics so laymans terms only would be appreciated. My main question is; should I be wary of the 330d ? If I bought one could I get these potential issues fixed before they become a problem? Any advise would be very well received.
