Hi guys. I am re-engining an '81 Cabriolet trying to use up parts I have squirreled away from 20+ years of working on VW and MB diesels.
I have a small pile of glow plugs, but only 3 that have a similar sort of "pointy/tapered" shape - I think the pn was 0250201032 which I think is really correct. The rest seem to have a more blunt end -perhaps these are MB?
IIRC, the injector is aimed at the glow plug on a VW, whereas the MB has an internal ball for this purpose.
Is there any real issue with using a "blunt end" GP on a VW? Just trying to use up all my stash.....

VW used both blunt and pointy glow plugs. You may find the more blunt ones are slow-glow. If memory serves, the mercedes ones are longer and won't fit.

that seems to be the case. All the blunt ended ones I tried as the fourth plug took more than ten seconds to get hot vs the other 3 when viewed through the open injector holes. I tried a Beru, Champ, Monark, and a blunt Bosch and all were slow...
