Hi all, I'm very new to the caddy game, picked up a 08 1.9TDI BLS last weekend, I was to give it a full major service so I was just wondering about glow plugs. Are they all the same ones or is there one with the sensor on it like I've had in the likes of my 2016 Audi A6 TDI? CHEERS!

Hi,
All 4 are the same. You can check the resistance to earth to see if they’re good. From memory the typical value is 1 Ohm, you’ll need to check and confirm this though.
You can also check with a scanner if they’re good or not.
Also, they can be a nightmare to remove, often snapping in the process!
