Any help with this would be most appreciated, when stationery and running at idle revs, my 56 plate 159 1.9jtdm seems to drop revs very slightly but very noticeable (although rev counter rarely moves) have just got it back from amc Chelmsford and they say it is worn gaskets on the exhaust recirculation valves, and because it is a gasket it is not covered under warranty, they have offered to up grade the gaskets for £118.
Any one had this problem? Does the diagnosis sound correct? And if so shouldnít this be covered under warranty? £118 isnít exactly the end of the world but donít see why I should foot the bill, the car has only done 25000 miles, alfa warranty runs out next month and would like everything to be tickety boo before this date.
