My Fabia VRs is 19 years old and I noticed that the glow plug loom is missing most of the insulation so thought I'd change it - splice in a new one. I'm an electrical engineer so no worries there 

 

What I did want to ask is glow plugs. Mine are original, never been out. So I thought while I was there I would inspect and check them and see if they could even be removed.

 

Well I did it, but one was a close thing with lots of creaking and an hour of sweat and Plus Gas and back and forward. I think another winter and it would be stuck solid.

 

All plugs were perfect electrically so I polished them and replaced (with a dash of anti-seize).

 

So what about your cars. Leave alone or did you remove - and if so how many miles did they last? Did they come out willingly? Honestly I'm impressed mine are still perfect working order - just the loom is bare metal! 

Just fitted the new loom for the plugs. Old one fell apart as I moved it.
