At idle if you have FRP jumping around then looking back through this thread you will see that it is often the Rail Pressure Regulator (FPR) on the Rail that fails not the DRV / IMV on the pump. Often perhaps not always.when Idling the specified was about 30 and actual was jumping around all over the place, and when driving the numbers were way higher and they were very closely matched, so it seems to be only at idle or below 1500 rpm ish that there is a problem.
How do you reset the IMV?garethkerr wrote: ↑Mon Nov 11, 2019 1:25 pmafter resetting IMV valve was good for around a month then back to the rough idle and as if the fuel line is being crimped at times when driving especially when cold.
What was your fix in the end? Many thanks in advance. I was possibly going to try a new IMV Vavle?

I have a T5 with a 2.0 TDI engine with the rough idling, after resetting IMV valve was good for around a month then back to the rough idle and as if the fuel line is being crimped at times when driving especially when cold.
