Seen a post on the Facebook pages the other day about this and mine does it too very intermittently, basically can be driving fine then all of a sudden starts running like its on 3 cylinders with engine revs erratic, 5-10 mins and its gone again
Seems to be very common judging by all the other guys on there who have it too but no ones exactly sure what it is!
The only thing I’m thinking of trying is cleaning egr as I hear it self cleaning when I switch off quite often so I’m wondering if it’s sticking maybe?
Anyone else had this issue, runs bob on apart from this every so often!
