2000 PFL 2.5 petrol manual CDX estate
This car often displays low screen wash level, thought the tank is nearly full. How do I rectify this?

Did my MFL 2.5 V6 CDX with bumper on    Remove grille and sensor on passenger side and pushes into big rubber grommet.  Was a bit of a fiddle and fingers in right place, but definately done with bumper on    Make sure you put back in the right way up !

New sensor was a few quid  , and ways bugged me as it always seemed to have the habit of warning you on the display of "Low Washer Level" just as the last squirt went on the screen !!!!!!!!!!!!!!!!  Grrrrrrrrrrrrrrr

Its mostly likely possible (well, definitely possible - you did it!) with bumper on. But as bumper removal is 5 mins (assuming screws in the wheelarches are OK), its quicker to pop bumper off

This car is PFL, early shape. I removed the bumper, and found the level sensor, as Al said, entering the (passenger) side of tank, blue connector. It came out easily. I checked in my spares heap and found the tank I saved off my Opel 2.5 MFL saloon, and the level sensor was at the back, as in RobG's picture. I took it out, same part and part no. as the failed sensor. I checked both with continuity meter and they both switched OK. The old float was a bit mossy, so I cleaned it. I tested it in water, and in less dense neat Opticlean, and floated in both. I conclude it was probably just in need of a clean, but anyway I put in the ex-Opel sensor.

The screenwash flow on this car is not so vigorous as my other Omegas. Is there a filter somewhere that I might clean, while bumper is off, to improve matters?

Thanks for all the help, Haynes seems unaware of the sensor.

Bumper off in 5 minutes, not this one. All went well until I pulled the bumper forward a bit, and found it restrained by by attachments both sides near the wing, only visible from below. N/s was a nut on a bracket, o/s was a cable tie. Haynes does not mention these.

Pull the pump out and clean

Pull the pump out and clean

Then pull the grommet out of the tank & clean the attached filter.
Also - stick a hose in the tank while the filters are out and flush the pond life out.

Thanks for advice. Have pulled out the pump, and the grommet, but found no filter. I can push a hose around the tank, nothing in the way. In attached pic there is something behind the pump inlet with 2 pipes attached, might be a valve for washing front or rear screen, might be a filter. There only 2 wires going to the pump so I don't see how the valve can be actuated. Is it a filter? Does it pull off the pump?

Pump with two hoses coming from it is the screen one with the filter

I believe the wee grommet is the filter. The bottom and sides of the grommet should have tiny holes. Any debris, sludge can be washed off and then pop it back in the washer bottle, making sure it's back in snug to avoid leaks and then push the pump back in. Fill with your chosen screen wash and water mix and give the screen a skoosh !

The grommet/seal for the screen washer pump should have an integrated "filter" as part of the rubber moulding. This is what you need to clean.

[terry paget]

Thanks again. You will see my confusion in the attached pic. The grommet with the open end is off the car with the poor flow. The grommet with the closed end from the GL I scrapped in October.

Problem now is what is the cause of the poor flow. My hunch is pond life from the tank has passed unfiltered from the tank and clogged the jets. Or might the pump be blocked? I have a spare pump!

[TheBoy]

Ah, yes, some numpty has chopped the bottom off.

[Diamond Black Geezer]

Ugh!! That would do it!!!

Yes, poor flow definitely looks likely to be down to this. Ok, here's a fairly stinky answer... Vinegar. I put a couple of pints of white distilled vinegar in my washer fluid for a period of a few days/week. It's brilliant at dissolving, among other things, limescale. 

Thing is, whatever the blockage, it needs dissolving somehow, as simply 'blowing it through' will never clear it unless it can get past the very fine jets nozzles. (alternatively write the jets off, bin and replace with new/good second hand.)

I've done it with mine, and although in truth not much improvement, one jet was a little weak, and all now squirt like a good un! Your car smells like a fish n chips shop for a few days, that's all. A good flush through with hose pipe/couple of old pop bottles of water to finish. 

[Diamond Black Geezer]

It's also nice to know whatever sediment or gunk is coating the inside of your tank and pipes has also been dissolved and removed from the system. 

Just had another thought, you could pop your jets off, leave them in a jam jar full of vinegar for a few days, then try them. Depends what your budget is, new jet £20, white vinegar 39p.

Vinegar's great because it won't eat plastic or rubber, which other chemical cleaners will. 

[05omegav6]

New are less than a fiver each

[Diamond Black Geezer]

Heated jets?

[terry paget]

Thanks for advice. Not quite sure how to pop off the washer nozzle. Looks like it come in from above and are is retained by 2 tongues. I have unclipped the cable, but the hose is still attached, and it looks tricky to remove, and to replace.
It would be much easier on the scuttle, where I see alternative mounts.
