Just had my 03S fail It's annual Ministry MOT test because one of the HID headlamp washer jets had gone missing, then I discovered that the jets were not available separately so I tried this little quick modification before the retest.
These little covering caps which cost pennies usually come in packs of two complete with self tapping screw and plastic washer for securing registration plates to car bumpers etc, I just discarded the screw & washer, drilled a small hole in the side of the black plastic domed cap and glued it in place ( gorilla glue ) over the hole left by the missing jet, it was a perfect fit, worked perfectly and it satisfied the examiner on the retest.
