My headlamp washers are not working, and in the UK this is (ridiculously in my view) an MOT fail. So the car is off road whilst I try to source parts.

New parts are on back order from Jaguar dealer with no ETA. Parts numbers I’ve been told I need are
RH Washer Jet – C2P23815
LH Washer Jet – C2P23814
Anyone know of an alternate source or suggest a way to get it through the MOT test?

 

Get it from another geo region?

How did the inspector discover that the washers do not work? They only operate every (I think) eighth windscreen wash attempt. Mine may or may not work, I've never checked.

 

According to the manual headlight wash operates on every 4th push of wash/wipe button - I would check that first, then have a look around the piping etc

 

In the UK, working headlamp washers (where originally fitted) are an MOT requirement on HID and LED headlamps only, because with some designs dirt on the lens can cause diffraction of the beam and potentially dazzle oncoming drivers.

In general any safety-related feature that was part of the original spec of the car must work. In the old days for example, we used to add rear seat belts to cars that didn't have them new but had the anchor points provided. These would not be checked at MOT time because they weren't part of the car when new.

 

It looks to me as if the jet does not have any electrical connectors and therefore does not contain the pump? If that is the case, I would just remove them and clear/fix them.

Since they only operate every fourth cycle, it'd be more likely that either the relay that opens the line or that which activates the relay is faulty.

 

Indeed ..... but, as the OP had already decided that he had to replace the jets, I had assumed that he could hear the pump running thereby, presumably, ruling out fuses and relays?

Worth a check - pump motor and or connector would be worth a look at too:

Thanks all for your responses;

I was originally told there are none in the UK but that they were being shipped from Europe, but these then disappeared. I’ll take a look at Guy’s link.

It hasn’t failed a test, my garage pointed it out during a service before taking it for the test. They are Jag guys so should know the intermittent nature of the operation.

thanks Justin for your comment - I had read that it became an advisory if they simply were not there, but what you say agrees with my guy’s comment that if they were originally fitter then they need to work.

I’m going to follow Richard’s comment first to try and clean them myself and question a bit more thoroughly on why they have said that is what I need.

 

Cheers!

 

I wouldn't assume that at all. Last time the Jag dealer changed my oil they used regular and not synthetic.

 

Been there, done that @McJag222 ,
But to be fair, the book does call for "conventional oil" for my car. But the service writer knows better when it comes to me and, had the offensive stuff swapped out before my eyes, within 30 mins, no charge.

 

The headlight washer uses the same tank and pump as the windscreen washer, only every fourth iteration. There is a valve that opens once every fourth time to include the headlights. If only the headlight jets were clogged, the washer stem thing would still poke out due to the pressure.

 

According to the manwell there is two pumps - one fer windshield and one fer pump power-wash fer head lights. Maybe it's a combo pump - I dunno

 

Dere be two pumps

Screen wash pump C2S4065
Headlamp power wash pump C2S4086

 

Ya teached me sumpin

 

 

Sorry, this is no help. But, you’d do better pissing on the headlights than using the washers. Their operation and functionally are pathetic,

 

I don't share that perspective.
