If it's anything like my 2.0 CDTi engine, then there are 3 different types of glowplug.
Cheapest first, working through to the dearest which is why you're finding some at £30, and others at £130.
Bog standard glowplugs,
Pressure sensor glowplugs,
Pressure sensor glowplugs for start stop engines.
You'll probably have at least 2 pressure plugs.
Plusgas is much better at loosening off seized parts than WD-40 is.
