I appear to be getting a smell of burnt diesel in my gt jtd the smell is worse when stood in traffic any ideas? the cab starts to smell quite bad and the smell is evident from outside also

A leak onto something hot (exhaust manifold?) perhaps.

Best get it investigated...don't think diesel will spontaneously combust like petrol will, but it can't be good...

Speaking of which (and excuse my ignorance), what's the normal smell of burnt diesel?
The reason for which I'm asking - mine seems to have sort of a sour, chemical smell (completely different from a petrol exhaust smell). Needless to say, the 156 I drive now is my first diesel ever.
