It will be interesting to see if they are of a different design, or just the warranty is just “built into the price”....quite frankly, other than the questionable design of the attachment point to the holder, there really is no reason why a glow plug with correct grounding should not last for a very long time.I was talking talking to Weber CS this morning about an ETA for my EX4 order here in Australia (later this week!!!!) and they advised that the glow plugs on the units released here will have a lifetime warranty.
That was one of the early problems. You can go into the controller, find the plug setting, and reset it. That message should go away.Mine's at 9 months and still working. The screen keeps telling me I need to replace it but it's still working so I ignore the message and it keeps working. By the way, how does the system know the glow plug needs replacing? Does it measure resistance maybe?
