Glow plug light flashing

[mlj76]

So to add to a very long list of issues, today the glow plug light started flashing, turn car over, starts fine and light goes off, drive for a minute or two and light starts to flash, car seems to drive ok

 

had issues with car dropping into a limp mode every now and again and is quite smoky of late not sure if these are all related!!

I'd recommend a diagnostic check to see if any fault codes flag up. 

What colour is the smoke? 

It could be an issue with the dpf, egr, injectors or glowplugs but I'm just guessing

It’s dirty smoke, usually black and mainly when accelerating, I’ve cleaned the egr, it was medium sort of build up. The little warning light is a new issue 😂 only came on today, the smoke and limp mode been happening for a while. Need to find someone to fault check car really

Would definitely recommend getting the dpf checked.
