Glow plug light stays on for a while when hot?

[sternal]

Having just had new glowplugs fitted the van starts a treat from cold.

When starting from cold light goes off after a few seconds starts straight away,

I have noticed on a few occasions that when restarting when the engine is warm the glow plug light comes on and stays on for a good 30 seconds then goes out! What would be causing this ? Any cause for alarm? Can it cause damage ? Van never did this with the old plugs when the engine was warm light wouldn't even come on.

As I said it's not all the time


Thanks in advance

Loose connection on the temp sensor. Defaulting to full heat.

ah !

would that be the lead that controls the temp gauge as well ? As I had to reattach this cos the mechanic forgot to ! (temp gauge wasn't working tis now)

No it's another one, Bentley or search will give you the wire colour/s.

thanks will have a look tomorrow

the wire that I reconnected was on the engine at the back (nothing to do to with water hoses etc) because this was off I had no temp reading on gauge, it could probably do with a good clean as its very corroded so will replace spade connector. But as you say its not this ?

thanks

Page 97.42 of Bentley shows the wiring.

Resolved !

Wire to the spade connector (by the rubber hose) had rotted away.

Thanks for your help
