That's really very helpful, thank you.

I am. Thanks a lot for this definitive response. I guess your reply may also explain the engine codes - code BLS on Owl's document must refer to engines sold elsewhere.

New member's first post, on this thread because my question arises from Owl's very helpful 'Octavia Mk2 Engine Info' document. I want to buy a diesel Octavia Mk2 1.9 PD TDI without a DPF. I can see that this depends on the car's engine code. Please can somebody explain what the engine codes signify, and how I can find out the code of a particular car I am interested in - or alternatively if there is some other reliable way of knowing whether the car was made with a DPF?
