My daughter has a 2013 Sharan ( this is her second Sharan ) and she has encountered a problem with diesel fumes in the car and depending on the weather these can be just about tolerable to intolerable. She was advised to have the ERG valve repaired which she did and the problem seemed to go away only to return in recent times. My questions are, is this problem related the the valve entirely, how much is the cost and replacement of a new one !. It is serious to the point where she wants to change the vehicle entirely when perhaps a change of valve may sort out the problem. Any advice or input is very welcome. Thank you.
