Headlight wash

There are two separate pumps, so a failed pump is an option. Another option could be completely blocked nozzles, due to a build up of grime. If it's leaking pipework, chances are you'd see a puddle of water under the front bumper when you try washing the headlights.

Would a scan show anything?

Highly unlikely, and in terms of physical access to the pumps to test them, that means removing the rear part of the driver side wheel arch, and you could try putting 12v across them.

Thanks for the help. I'm thinking the problem might be cracked pipework as there was a bit of a puddle under the nearside bumper I've since discovered. I'm struggling to find a diagram of the pipework routing so looks like I'll just have to get in there and have a proper look.

Here's what the pipework looks like. Chances are that if the pipework is still intact, then the leak could be occurring at #12, the o-ring (N90303801). The only other spot might be at the connection from pipe #1 to pipe #5, but I don't know if the diagram is accurate, with the joint being in the centre. Since it's tucked up inside the bumper cover, water could be running to the passenger side. Time to fill the tank, use the headlight washers, and get under the front of the car.

Just to follow up on this...car is off the road. I 've had nowhere to work on it this last year or so (with all my tools in storage), so was waiting for my mechanic to come back from his holidays. I had previously parked nose-in too close to a kerb some time ago, so as you can see in the photo below - the bumper cover getting disturbed has probably dislodged a water hose connection.
Things have now ended up that I'm going to have to try and fix it myself, so hoped someone could tell me before I go through the hassle of extricating my tools out of the storage unit, if the headlight washer hoses can be accessed without removal of the bumper cover?

On the PF D3, both the wires and pipes run along the bottom of the bumper, within that section below all the grilles. I've highlighted where on your photo in red. As best as I can see from photos on eBay of FL bumpers, the wires and pipes go along the same route.

As for getting to them, I would say the 'easiest' option is to take the bumper off. Getting at the pipes either side of the main grille may be doable, but problematic, as the wires and pipes are all clipped into place, and I reckon getting at them behind the main grille would incur some swearing. Considering the bottom of the bumper extends quite a bit, you'll be reaching in about 6-8 just to reach them.
