I know there is little need for the glow plugs in Australia but for members in cooler climates I'll share how I fixed the relay that would stick in a closed circuit keeping the plugs on all the time.
I opened the relay and found 3 electrolytic 100uF capacitors. 1 rated at 10 volts and the other 2 at 16 volts. I have a fancy meter that showed the caps were no good so for a grand total of $1.26 I purchased 16 volt replacements for all 3. At about 1/100th the price of the new replacement relay it's back working again, if I ever need it. Not now, though, I've pulled out the 60A fuse to the glow plugs.

I think 2 of the caps, in parallel, may be part of a timing circuit. I didn't trace it all out. My meter does ESR and the old caps showed high ESR and low capacitance. There wasn't more than about $5 worth of parts inside. Even the IC is only just over $1.

SupporterRick that's great but what vehicle and engine are you talking about - I assume not my 2.7 TDV6.

It's part number PRC6913. Mines a 300Tdi but I believe it's used in the 200Tdi as well. Possibly others. I suspect that other relays could be similar in how they work and can be repaired. Not much to be lost to open up a broken one. Hope that helps.
