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 an 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.
Update - I got a blanking plate for the valve/air box. It still did the flashing. I located a electric/vacuum valve so disconnected the power - sorted (bodgedI 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.

)Nice one Nige 
Did you notice any power hesitation before your repair?

Latest update - van is in for welding and new front wheel bearing ( MOT ) But the glow plugs and relay are still clicking on/off while it's warming up - on tickover it doesn't like the extra hot air and " misses" a bit - fine when warm . So it's the Final Solution time - I have some heavy duty 2 pole Toggle switches and I'll wire one into the actuating wires going to the relay. ON for a cold start then OFF for the rest of the day. And maybe a security thing cuz it won't start if nicked. Not that anyone would bother LOL
