Gents,
Thanks very much for all of your advice. I must admit, I was reading a lot less of issues surrounding the 1.8 engine/fuel system, compared to the 2.0 litre engine/fuel system. I was so concerned about the issues surrounding the Injection System on my Mk 3, 2 Litre, that I was even considering buying a Citroen C5, only to be informed that they are plagued by expensive electrical problems (and in a car which has a dash board like a modern day airliner, I do not need those troubles

).
I really like my Mk3 to drive and it averages around 49.5 MPG without burning a single drop of oil, but I had the whole injector system replaced a couple of year ago due to Flashing Glow Plug/Cutting out issues, on the advice of my local Diesel Specialist and this summer, in the hot weather, it was a nightmare. Any stress on even slightest of inclines was causing the Coil Light to flash, followed by the engine dying. Saying that, now that the cooler weather is here, it is only when I boot it a little that it is doing it, but I do not want to spend anymore silly money on it. I think I will look at a couple of 1.8's.
