just got a letter from nissan for a recall.
the automatic tensioner bolts for the yd25 may not have the appropriate tightening torque applied.
hoping i can get it booked in before we go away over xmas, will probably do at least 4000km over that period with the family so will be good to know it's been sorted.
will give them a call tomorrow.
interesting to see if that's Nissan talk for we stuffed up and were replacing it.
