Hi, I bought a 2.5tdi cabby last summer, and absolutely love it. Had the Cambelt changed as there was no record of it having been changed and although it only had 42k on the clock, it was 7 years old, and I didn't want to risk it. Aside from that, I had a custom remap carried out so it is knocking out just under 200bhp, up from the stock 163bhp.
I have done about 9000 miles so far, mostly dual carriageway/motorway miles, and it averages low to mid 40's mpg. This is the 34th car I have owned over the years, all makes and models, new and bangers, and I have to say the cabby is a superb car. It just oozes quality, you won't be disappointed.
