Soaking as suggested but I don’t think they will be coming out soon. Appears to be the earth strap.Soak glowplugs with Plusgas for a couple of days before removal - easy removal !

Battery appears very good. Prime suspect is an earth strap.When you check / change the battery it is very important that the battery terminals are clean, the leads are firmly clamped onto the terminals and the little black block to the left of the positive terminal is tightly bolted to the positive clamp and all the internal connections inside the block are tight. Be careful not to short these to earth while tightening them!!! The other often problematic lead is the starter to body earth just below the ABS pump / left head light, not only can it be loose, but can often be corroded internally so just checking it is tight is not enough. Many of us run a secondary body to engine earth as an insurance. Glow plugs do fail but it is obvious the car is only running on 2 cylinder when that happens, but if there power supply is too low they are not getting hot enough to warm the cylinder to burn all the fuel. When the engine is warm the glow plugs are not required and the engine will start with no or far less white smoke.
Strangely enough the one earth lead I would have though to cause more problems does not appear to be causing any. That is the one that runs from the battery negative post to the chassis just in front of the left rear wheel.
What a job; a cable tie, one bolt and one nut took me 3 hours! Main problem was the bolt to the space frame, solid with a white powder. I assume the white powder is salt but I don’t see it on steel cars so perhaps it is aluminium oxide?
Was so cold by the time I finished I didn’t bother trying to start. Fingers crossed for a less smokey start this morning ?
No i dont think so was later on when they became tied into engine management i know i can unplug mine on the 2005 galaxy 1.9 pd and start the car and no faults are shown or recorded in ecuThe engine is turning over better but still producing lots of smoke on cold start. Felt like is started on two cylinders yesterday. Switching my attention to glow plugs.
Is there no warning light for glow plug failure on an A2?

no monitoring of the glowplugs by ecu on the A2 easy to test with a jump lead though they draw a fair currentThe engine is turning over better but still producing lots of smoke on cold start. Felt like is started on two cylinders yesterday. Switching my attention to glow plugs.

Hi Philward,First cold start this morning with new plugs; started instantly with no smoke at all ?
Thanks all for your help and advice, slow cranking was caused by corrosion of the engine earth connection point on the space frame and the smoke was the result of at least two glow plugs having failed.
I think they have done about 80k miles, only ever changed them once and owned the car from new.Hi Philward,
Have you any idea how old they are ?
I’ve got mine to change this weekend.
Thanks
Keith.
I retrieved my old plugs from the scrap box to see if they had a manufactured date on them. That way I could advise kp 115 the miles they have done.
One of them looks like it exploded, hopefully the bits will be long gone.

While looking for a date of manufacture I noticed that the plugs are marked 5V:

Have I been driving around with TDi 90 plugs in a TDi 75? I thought this combination melted piston crowns?
Edit, indeed I have, Beru 0 100 266 008 are 5V plugs. Car runs fine; what damage is likely to have occurred?
