    I tracked down what I thought was the noise of a sticky tappet to this little chappy.

    It says 'LOW' on top of it and has a few electrical cables goig to it and appears to be attached a fuel line. Rather randomly it seems to make an irritating tappetty noise.

    See item circled below.

    I'd say that is the fuel vapour purge valve. Take it off and clean it out, maybe a shot of brake cleaner might do the trick if it's excessively noisy.

    It is the fuel vapour valve. They do tick and its normal.

    Are you sure it says 'LOW' and not 'MOT' upside-down ?

    As said already, it's a valve and they do make a light ticking noise as they operate :)
