Hi,
I have this fault on my 2011 1.5DCi - tried injector cleaner in the tank but that didn't help. Engine sounds like it's misfiring and juddering, plus lacks power. It comes back right away after starting if the fault codes are cleared.
I got a used replacement from eBay, but it turns out to be not the right fitting, even though it's supposed to fit my engine - that's another story though...
So I removed injector 1 and tested it with a multimeter - came out at 199 or so ohms ( set to 200K), which is the same as the one I got off ebay. I gave it a clean but that didn't improves things, so I swapped injector 1 with injector 3 (also reading 199), cleared the fault and it came back with the fault still as P0201 - Injector open circuit (which is injector 1), so this suggests to me that the injector is fine and it's something else in the circuit. What could that be?
I have sprayed electrical contact cleaner on the plugs going into the ECU and they look fine.
Since reconnecting the injectors I also have a bit of a fuel leak, but I assume something is not quite as tight as it should be!
Injector open circuit P0201 fault

Hmm, according to this post, the injectors are numbered 1,2,3,4 from the left (when standing in front of the car, facing the windscreen):

But elsewhere I am seeing that in this engine, the injectors are in fact numbered 4,3,2,1 from left to right, which may explain why the fault has remained in injector 1 if I swapped 2 and 4!

I had the same open circuit on injector 3, replace with a new injector, 2 weeks later same happens again so I swapped 3 and 4 but still showing open on no 3. Did you solve your problem, if so how. And did number right to left.

This is how the cylinders on a 1.5DCi are numbered.
