Glow plug light stays on now at 130k kilometers

[Nicky]

I have a 2015 TDV D4. Even at operating temp Glow plug light it is still there.
Car runs fine regardless, the light goes off of course after a short interval when
I lock the car

Maybe an issue with the relay.

Maybe an issue with the relay.

Turns out it was the 4yr old battery that was holding charge but barely enough cranking voltage.
