The wifes P38 has always been a bit of a pig to start from cold. Recent frost was the final straw, flat battery, the whole nine yards.
.....took it to Strathearn to find that 4 of 6 glow plugs were gubbed and a 5th expired while they were working on it. Amazed it started at all !
It now fires up if you so much as wave the key near it, much better !
