Guys, my old (2001 ) combo with the "no electronics" diesel engine has a problem with the Glow Plugs heater (relay clicking and warning light illuminating ) while driving for aprox. 1 second at random intervals. I found the relay and got a new one (£8 ) but despite searching the www I can't find 'owt else to do with it - so I can't even jury rig a supply (from a fuse ? ) and a push button to operate the glows manually. Any ideas ? Thanks.
