I paid a few hundred to have the glow plugs checked but they could only test all  but one as it was seized and, as suggested, not a good idea to try to free it or it could ruin the engine. This expensive diagnostic didn't help at all and no glow plugs needed replacing either. However, after replacing the fuel filter with a FRAM, which only seemed to make a slight difference, it was suggested that I try turning on and of the glow plug position one on the ignition for about 15 seconds for three or four times as sometimes apparently older plugs can take longer to heat up. This did seem to help but, as I said, the problem disappears once Spring arrives. So it does look like Jaguar have a major problem with ineffective glow plugs, all injectors prove OK on testing. It would be great to hear any updates from the manufacturer on this inherent problem as I will be upgrading to an XE saloon one day. Cheers everyone !

Not only technologically advanced but the most economical engine I've ever had for a Jag. High 30s around town and up to 50 on a run !

Incredible for such a powerful engine and a car known to be a real gas guzzler.

If I ever have to get rid, I'll be getting the same engine. I've heard that one of the Land Rovers use the same block as it's so reliable and strong.

Hi Keith,

are you saying that changing the fuel filter cured the cold start problems ?

I have the same engine which is hesitant to start and then runs rough for a minute or two until moving off.

However, this only happens when the weather turns cold and first thing in the morning.

Many thanks,

Ross
