I have the warning light on on my dash. I suspect one of them has packed up

Is there anyway of disabling the glow plug warning light until I get it fixed?

Thanks

Probably not. Not that expensive to get new glow plugs is it?

I've got the same the garage checked it and said it was the relay and not the plugs n not to worry until it starts getting cold again. If it flashes and goes out after warming up it should be fine but if it struggles to start it could be a plug. Been quoted £150-£200 for relay if u have to go down that road (fitted) hope this helps

Mine came on and off for 4years never replaced started fine, only worry if your having trouble starting
