Hi all , I’m having problems with my 2.0 d R-sport XE . I’ve recently had a full service and since then I’ve been driving the car with no problems then all of a sudden whilst driving- my throttle doesn’t work. Then on idle the rev’s were going up and down on its own, Happens quite offen , it’s dangerous whilst on a busy road . I have put it into the garage and a few things flagged up on the machine , So they … changed the throttle sensor , piston oil control valve , engine flush . Oil filter and oil . £650 and only picking it up today, and it’s still happening. Anyone had this problem? thanks mark
