Rick.

What I assume to be nailing was still there on start up. It manifested itself as a single bang every few seconds but I did not notice it again after backing the car out of the parking bay or for the duration of the test. I'm really not sure that it was nailing. I dont actually know what that is as I've never owned a diesel before. Maby I was just hearing an unfamiliar diesel noise.

One thing I forgot to mention was that the oil pressure climbed to max a few seconds after starting and when it reached operating temperature it would idle with the needle directly in the centre of the oil pressure gauge.

As you are diesel driver please anser me this. What does the little switch under the left hand instrument cluster do? When I turned it left and right it had an effect on the idle speed. Is it similar to a choke on a carbureattor car and when is it used?
