Are glow plugs on a service schedule?
My 2006 D3 has a LR service history for at least its first six years and hasn't needed any head work but I wonder if it ever had a glow plugs taken out at all since it left the factory?
Reading all the horror stories of broken plugs on this forum has put the fear in me.2016 D4 SDV6 Landmark

Not on the service schedule, very unlikely that they have been changed ( but may have been done). You’ll find out, if it won’t fire up on extremely cold mornings ....... A fuel burning heater remote control can be a rescue line, if you can run (the fbh) 20-30 mins before attempting to start the engine. Otherwise, it is the very real risk of the plugs breaking off when removing.D3 owned from new, P017 brake recall, BAS FBHIC, new FBH, LR013487 oil pump, new water pump.

They are supposed to be renewed every 105 k miles or 7 years according to the maintenance check sheet. And it can be done, had all of mine changed 6 months ago, and I suspect they were 12 years (never renewed).

And don’t confuse the symptoms of failed glow plugs for worn out injectors, the symptoms are very similar. My glow plugs were well and truly knackered, until I had a chance to swap out all the injectors. Then they miraculously worked.

Good point re. spark plugs. The maintenance check sheet states spark plugs, but does not indicate any distinction between diesel and petrol models, a distinction which is clearly stated on a number of other points on the list. If this is applicable to both diesel and petrol vehicles, then it must refer to glow plugs for the diesel engines. But now that you mention it, I am confused...

It is just not applicable to diesel cars.

I just had 5 of mine done; apparently the 6th cant be done without a lot of work???
Its made a huge difference for me. I paid £175 all in. None snapped. Make sure the engine is red hot and work is carried out immediately and much better chance of them staying in one piece upon removal (apparently)

I had all 6 done, and indeed the final one took a lot of time and extra effort to unhinge, which made a significant impact on the bill. So I wouldn't trust the time estimate given in the maintenance manual. But none snapped so no complaints after all.

Glow plugs are not referred to on the service schedule. So no interval change. Spark plugs aren’t glow plugs

When I bought the car I got handed quite the pile of service and parts receipts so being a fan of spreadsheets fired all the details including costs into Excel, now I can search/filter it for any captured history of tyre changes (and there's been a lot) for example. It's really quite good if you like that sort of thing.
I suspected some thing was up with the plugs the other morning. It was frosty and the cart took quite few turns to start. It was a bit smoky too for a while. Anyway following an investigation I have only one working glow plug, well I should say only one with continuity, I have to assume it is working.
The new plugs remain in the drawer of hope for now.2016 D4 SDV6 Landmark

I'm collecting parts of the next service... What's the preference on manufacturers for the glow plugs? I don't think mine have been touched
