My Audi A4 is shaking when in idle

[Jay74]

Any advice my Audi A4 is really sluggish and shakes like it is gonna stall when in idle when driving it’s fine I’ve changed the egr valve and cleaned the throttle body but no difference it has come up with a code P106500 could it be this as I don’t want to pay out 170 quid if it isn’t this 

thanks

Hi, there are two fuel pressure regulators in the system, one on the HPFP and one at the end of the fuel rail, my guess is its the fuel rail sensor as if it was the pump sensor it would not run well at any rev range.
