Moin municipality! Actually I’m on the road with the Benzen, but today I need your advice: Friends of with drive a 2.5l diesel V50. Year of construction and further details I could submit if necessary. Problem is that he already has a change of diesel in the engine oil again. Volvo finds nothing and wants to play Teilelotto at the expense of my friends. Supposedly there was a call back, but since the car was bought used, there was apparently no message. Question 1: Is such a call over the KBA and all holders are notified? Question 2: Was there such a call back? Question3: What could it be about that Diesel comes into the engine oil? Thank you in advance! Jürgen
