Hi, i own a 2.0Tdi 184hp leon 2015 with 77k miles.

My car has started to have a rough idle when it is in Park it idles at 1k and there is a vibration/shake. The dpf is not blocked as i have done a forced regen and i go on motorway drives atleast 4 times a week.

Does anyone know that the issue can be?

I have taken it to a mechanic and he did say there was an injector imbalance, there is a loop where injector 1 goes high then drops then injector 2 goes high and drops and the loop carries on.
 
I have a 2014 184 and had similar issue. It was an injector imbalance. Mine are getting replace shortly.
