Not Vaux - but a Fiat 1.9 JTD (So a bit like the new VX's)
It has a tendancy to cut out, its just been serviced and that didnt cure it.
they didnt replace the glow plugs - now if it was a petrol car - I would say it was poor sparking/sparkplugs. But it being a diesel I havnt a clue
and what do glowplugs actually do other than pre-warm at ignition?
