406 1.9 TDI

They all come out without any special tools or techniques. Just a bit of patience. If you're going to do one, then do them all. Shouldn't cost more than £30 for the lot. I got Beru from ECP last time.

First of all Mike, I hope your diagnosois is correct, although in my experience plugs out means black smoke on startup. To answer your questions though. The only effective way to test them is to put em on a battery, I've always found resistance checks inconclusive. I tend to leave changing em to a garage, two are easy, one's difficult and the fourth is a ba*tard to get at. (I used to do the plugs on my old diesel 305 without breaking into a sweat) If one or two's gone the others won't be far behind, and sods law dictates that if it is only one, it'll be the one behind the pump. imo.

On this subject. I have just had all 4 glow plugs replaced on my Pug

Why is this? Is it just because it's getting colder in the morning at this time of year? or is it mainly because my Pug is getting nearer

Mines still running perfect, no problems, starts first time, with 158k on the clock

I don't know why it's doing that, unless one of the new plugs was duff - not many people (including garages) check new plugs. Another possibility is that you have a poor connection somewhere in the glow-plug circuit (glow-plug relay or wiring) At 110k miles the engine is barely run in, so I shouldn't worry about that.

Another one is they fitted the wrong plugs, or couldn't be assed to change em all, some of these monkeys don't give a stuff. Generaly it shouldn't need two goes at the plugs even in the dead of winter. All the Pug diesels I've had, including a 405 with 140K on it, started first turn when the plugs were ok.
