update: new hpfp fitted no changes, reading up could be a remapping fault or a J538 possibly but garage wants to fit an entire new hp fuel system rail sensor etc but not usre if that will work they even said, at a lost with this tempting to do a remap to stock and j538

New control valve is £140 or so might try it and se, Cheers

I believe I set it up correctly, from what I understand theres one on the fuel rail on the right hand side, a sensor on the left and then one on the HPFP is humming a bit after doing the drive

I have a 2013 skoda octavia vrs. Had to have new cylinder head, injectors and fuel pump(s) changed due to a garage error. All was fixed now the car is sometimes rough idling and when getting to 60mph or high glow plug light comes one and error codes p0087 and p1065 appear. Theres 4 sensors to change any advice which one to touch first? Either the control valve on the HPFP or the 2 in the fuel rail itself?
