So today i find something new on my car, headlight washer jets never used until today and no idea why they came out. how on earth do i retract them i can see no button and they dont look like they could handle a motorway drive in the open position without getting damaged 

Hello Paul, 

I'm not sure if I'm reading this correctly, but has the centre come out of the actual jet surround and left a hole where it should have been? If so, I think the basic holder is "clipped in" from the outside with the normal expanding/contracting lugs, and once in position, cannot be extracted from the outside. If so, you will guess what that leads to! 

Kind regards,

Gareth.

Worked out that if my lights are on and i use wipers the headlight jets operate too but dont retract back when lights or engine is off?

just checked the car after a few minutes and they must be on a timer as they have now gone back in, strange lol
