Dealers are washing their hands of it ,they try to claim that is normal for princengine to sound like thatbut let's say is if this noise will presist over warranty and then u will have to pay 4 new engine ?????? is it worth it to try resolve it b4 it happens?
Though we do feel engine noise in the new "N" motors is normal, that is not to say you dont have an issue. I would never say it is a non-issue with out listening to it. To be upfront yes the direct injection, hydraulic lifters, Vanos system and for the turbos... the vacuum pump do all make noise that few people are used to. If your in the area stop in, we can listen to it and take it for a ride, we have had only one issue with the new motors, but thats not to say there isnt another one here.
