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?

Could be the new fuel pump isn't set up correctly or perhaps the fuel pressure regulator if it hasn't been changed

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

Not sure if it normally makes a noise re HPFP sensor/valve. Might be worth changing it to see if it makes a difference depending on the cost of a new one.

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

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

I'm new, I just bought a 2012 Skoda Octavia, and after correcting certain things, the same sensors as yours are showing errors. A thorough check revealed an electrical short in the branch that touches these three sensors. This post prompted me to check that part. You could check that, it never hurts...
