Will my Merc fail its NCT due to glow plugs?
The glow plugs on my diesel Mercedes are poor and it will not start easy when it's hot; with an NCT due in a month's time I worry it may fail due to the heat plugs. Will it?

Hi Adrian,
There is no mention of glow plugs or indeed engine starting in the official NCT testing manual so you should be ok, though we'd still recommend getting your car sorted beforehand.
