Technical Poor Start - Anything to Worry About? (1.9 150)

[Andysan]

Hi all,

Left work today and started my 1.9 150 Sport JTDM as normal, by allowing the glow icon to disappear before cranking the engine, as per normal. Outside temps were 18*c so I didn't double glow or anything. Have the odd splutter as all MJet owners probably do, but it was a good five seconds before it would start. I tried again and noticed a very large combustion that shook the car, followed by quite a large cloud of s*** was thrown out of the tailpipes - car ran fine thereafter.

Would like to know from a technical perspective, why on a warm day maybe once out of every half a dozen starts a diesel engine has troubles, and why on this particular occasion it felt like a bomb went off under the bonnet? I'm guessing there was excess fuel in the chamber from the first attempt? Anything to worry about - my plugs were done about 30,000 miles ago now...

Cheers.

I think u dont have nothing to worry about it, because mjet engine in very sensible on fuel, my was doing the same (about 5 times on year). My mehanic said i can try fuel aditive-injector cleaner and i am using it every 6000miles and i dont remember when i had bad engine start, or the better option is to clean the injectors with ultrasonic cleaning.

Have fun.
