Noticed that the glowplug light on the instrument panel hadn't gone out after the engine had started.
First off dabbed a wire from the battery positive in turn to the tip of each plug.
Found one that didn't give a spark.
Measured that one with my multimeter and found it was open circuit, luckily this was the easiest plug to access on the engine.
The others were about 1 ohm.
Checked the glowplug relay and found all 6 outputs were okay, not suprising as the plug had gone open circuit not short circuit.
Bought a 10mm 1/2" drive deep socket, a can of unlocking spray, and a new Beru glowplug.
Make sure the socket is deep enough to go over the top push-connector section and fully engage the lower hexagon section on the glowplug, even when attached to your 1/2" drive t-bar or torque wrench.
Applied the socket with a torque wrench on a warm engine.
The plug clicked and started to turn at about 20ft/lbs, and unscrewed and pulled out easily.
Didn't need the spray can.
The old plug was Beru and marked A001 159 49 01 on the shaft, the new Beru was 0100 226 379 on the box.
This was only the second fault in the 3 years I've had the car, at 44K miles now.
About a year after I bought the car the gearbox lost drive halfway through an overtake, very scary.
Pilot bush was leaking so replaced and ATF and filter renewed and okay since.
Also learned from reading this site that glowplugs are only needed in cold weather.
I've been religiously turning on the ignition and waiting for the glowplug light to go out and only then have I started the engine.
Thats a few thousand heat-ups I could have avoided it seems.
