Oil light issue now sorted. Basically what had happened was someone had whacked it on the bottom of the sump (I'm pretty sure it must have happened when it was in the garage having the auxiliary belt and tensioner done) because I haven't done it, and it broke the oil pickup pipe (they're plastic on these cars). So when it was on the flat all was well, but going round steep corners and the oil going to one side of the sump it wasn't picking up enough.

So, I've fitted a new pickup pipe, a brand new sump, and done another oil (Magnatec) and filter change, so the oil is mega clean now. Took it out this morning to my mums (30 mile round trip) and it's spot on, no oil lights and the engine is really quiet. So the car is up for sale now.

I would say if you want one of these seriously consider mine, you can buy them cheaper but I doubt you'd get one like mine, massive history and really been looked after, I am the second owner, had it 7 years and done nearly all of the mileage in it (virtually all motorway with the cruise on), and it's very highly specced too.

Give me a shout if you're interested.
