For mile's I really don't keep tabs on. If I did diesel would have been the better car for me or even worse a Prius :) but the car does run better on the extra cost stuff but have said before I use the extra fuel additive not all the time but from time to time to help combat this :)
It's like Santa's grotto :D Look's like you will be busy. And I know what you mean about the weather, I want to try refurb my alloy's over the bank holiday, but it's meant to be nice here so fingers crossed for us both :)
I'm a member there also but other then a very few people I have met and the info... Lets just say it's not a place I like :D
And no not fell out with anyone on there either :)
Wow that would have been my last guess too :o But on the plus side least you got it sorted, just need to get the sucker MOT'd and good to go again :)
Take it any mods planned are now on hold :( And thanks for letting us know :)
I would try reset the ECU 1st as it's the easy one of the two choices ;) If it still fails would then try the wiring loom. Just to eliminate any problems before getting a garage to check it over.
For some reason I can believe it too
It's no good now trying to make it out like you put them as a joke ;)
Here's one the Woolpacker's reminded me of for some reason
Hope this helps

I guess the part numbers wouldn't match as there swapped round to ours. Unless because it's electric the plug's may differ, but still a nice try. And I've never thought about trying over sea's for parts :)
