    The ticking noise could be a sticking valve, the headlight wipers only work when you use the windscreen washers. :thumb:

    I think halfords sell the continental type fuse in plastic. :dk:

    Ticking could be worn cam lobe (if noise constant), or sticking tappet (if it comes and goes).

    The headlamp washers only work when headlamps are ON, and you work the screen wash - but they are probably broken, usually are.

    Have you changed the oil recently?

    Sometimes a good long run + fresh oil can help, you could try a flushing agent if you like - some people might advise against it at 200k miles though.

    Does it tick all the time, hot and cold?

    Well - as a cheapest option, you've nothing to lose by doing an oil change, and maybe a flush as well.

    My old 300TE didn't tick, was quiet as a mouse with 198K under it's belt.

    A can of 10W/40 semi-synth and a filter should be cheap enough £15-20? Got to be worthwhile, especially as it was standing for so long.
