I've been thinking about upgrading my mk1 Octavia TDI elegance to a mk2 TDI elegance spec, I've notived that some are 1.9 105bhp and others are 2.0 140bhp. Which is the better engine? Do the they both have dpf filters? I know the 140bhp will be quicker but I would rather long term reliability over speed as it will be my new family car! My mk1 has been excellent car but its starting to look tired now
