Default glow plugs stuck on

Not sure why, but if you watch my recent video, I mention my glow plugs are still on.... any idea why this is? I tapped the relay thinking it was stuck, but its not.

Im glowplug-less now.

Any ideas?

If they are on, the relay is bad. It must be stuck there is nothing else that runs them. Just get yourself a high amperage starter relay and wire it to a push buttom switch. Cheap and easy fix. The volvo relays are expensive no matter where you buy them.

I also had that problem, i replaced the Volvo-relai for another Volvo-one because a had a spare.
To notice if it happens again, i placed a second seatbelt-reminder-light in the middleconsole paralel to the glowplugs to "see" them glow.
So i can even notice if they're glowing a while after the engine just starts running, especialy in wintertime.

Ya know it could be the temp sensor, you should check that for resistance against the other one, they are both the same sensor. Don't really hear of them going bad all that ofter but should be checked anyway.

Ya but could the temp sensor cause the GPs to stay energized? Thought the temp sensor only provides signal to cycle the GP relay for a period of time-- not able to force the relay to stay energized over its "max" time?
