So... the inevitable 'HDi won't start' thread...

[Fooby]

1 know the following things:

-Battery aint great
(gauges flashed all full then back to bottom again), but its always turned over/started.

-Possible key/immobiliser issue.
Sometimes it just turns over and doesn't start. Pull the key out, put it in and start again, fires first time (rare, 1 in 10/15 times)

First time up in Cumbria with this car, left it standing for about 48hours in what has most likely been the coldest its ever been since I've had it.

Car turns over ok, but refuses to fire.

I've locked/unlocked the doors, with the remote fob a few times. Turned over a few times but still never fired.

obviously, battery is a little tired now, so i'm tempted for the sake of it to just replace the battery as first point of call.. but since it turns over I figured it would be alright?

Immobiliser issue has turned into a permanent fault... unknown if that's the case, is there any way i can test? All my spare keys are at home.

I do have RAC and I will phone them if required, just don't want them to rock up and tell me something obvious.
