I guess I read and research too much?? Well anyway I like to make an 'informed' decision. Picking up a 53 plate 1.9 tdi pd soon as a replacement for my V70 2.4 petrol. Basically it just fits the bill, big on space, big on torque, big on mpg and judging by this website very big on a following. Hoping I can contribute as well as taping in on your knowledge. I am a diesel burner engineer (oil heating, incinerators etc) so one of the first things I'm going to do is take apart this auxillary heater that is the cause of so much writing on this website and see if I can set a few things straight in my own mind if not anyone elses. If it is what I think it is we could all help each other. Anyhow, speak again soon
