Rev needle is fine, it's a shudder through the car.
Its due a major in 6 months so maybe something they do will sort it out
Sent from my GT-I9505 using Ford OC mobile app
I have this engine on mine and I feel a shudder in the cabin at idle, apparently it is something to do with the the engine revs fluctuating to keep the emissions low!
I had the same concerns as you but was told not to worry.
If you put the car into a diagnostics live data mode, you can actually view the revs digitally and you will see what I mean, they are constantly fluctuating between 700-750rpm
If you don't know how to set the car into diagnostics mode, let me know and I will tell you how?
