Tried Googling this and I just get conflicting opinions. Is a permanently lit Glow plug light on the Dashboard a MOT failure ? If its of relevance its on a 2010 Suzuki Vitara. I would appreciate an informed response.
 
Yes a warning light is a fault thrown up on management system which is a mot failer.
You don't know if that is a major or minor fault.
Maybe that's where the confusion is.

Ask garage to look at it first then decide how to proceed.
 
Don't know about Suzuki but the glow plug light illuminated intermittently on my 2002 Octavia.

It didn't have anything to do with the glow plugs though...

The brake light switch was faulty!
 
The glow plug was permanently illuminated on my Megane back in the day, Renault said it was a faulty wiring loom so I lived with it permanently.
