    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.

    I guess your van doesn't have a DPF Nige, but it will have an EGR system. If its getting blocked you can get symptoms such as yours.

    It does have ab EGR - it's a mechanical one with a valve operated by a vacuum pipe. Would one of the aerosol cleaners - squirted in the inlet manifold - work or should I take the valve out ? I'd never have guessed it was about the EGR valve . Thanks.

    I can vaguely remember doing something similar on a friends 2001 combo years ago. IIRC, the relay was behind the passenger kick panel and I just disconnected the relay switch wire and operated the relay by fitting a press button with a switched live feed on the steering column shroud.
