On some engines without normal glowplugs there is one glowplug in the intake manifold together with an injector. While the starter is operated this glowplug and injector is energised. This injector does not work like a normal one but is an electric device. This set up supplies the engine with some preheated diesel in the airsupply and helps the engine to start. You will find this on some tractors."

Definitely NOT the case in the i30.

I agree... from the same Posting "Some direct injection engines also have glowplugs to assist the starting. Smaller car engines are normally of the sort that do need glowplugs" (to assist starting  )

btw i learnt all this 2 weeks ago in tafe, 1st year diesel mechanic apprentice lol

I'm glad I didn't attend that school, or whatever it is...

Just stumbled across this post. Our 2011 i30 CRDi feels like it 'stalls' when I turn off the engine. As compared to my previous cars, when I turn off the i30, it tends to 'shake' a bit. I've used Shell diesel and now running on Vortex and no difference in the engine switch off. Been like that since we got the car about a month ago. I thought it might be normal for diesels, but this is our first diesel so we weren't sure what to expect!

Normal I'd say from my experience with diesels.

i know this is an old thread but just to clarify, the i30 diesel doesn't have glow plugs, glow plugs are only needed in a pre-combustion diesel, i30s are direct injected so no need. they do however have a intake heater of some sort, just to warm the air to air initial combustion on a cold start.

That'l be dam...

I changed all 4 glowplugs in my 2008 CRDi last year..
