I need to replace the glow plugs but I have two simple questions:

How do you know if the are 7v or 5?

I keep reading that people are buying plugs from Europe for like $25 each, but so far I have struck out... does someone have a source they care to share?

Thank you! (and yes I did a search but was overwhelmed with results )

7v steel glow plugs will drop right in, and work without having to re-flash your ECM to recognize 5v.

Sweet! Thank you very much.

I was in a bit of sticker shock. $20 for four glow plugs for our VW Golf; $360 for four glow plugs for the CRD.

You should double check me on this, but I believe if the glow plugs have red bands around the tips, they are 5V.
