If you're not completely familiar here is a rundown on body styles and engine combinations:
1999.5 - 2003 models: A4 Chassis, rotary pump engine (90HP, 150lb/ft).
2004 - 2005 models: A4 Chassis, PD engine (pumpe düse; pump injector. 100HP, 177lb/ft).
2005.5 - 2006 models: A5 Chassis, PD engine. Completely different looking model that used the previous generation engine.
2009 model: A5 chassis, common rail engine. Old body, new engine (140HP, 236lb/ft).
2010 model: Going to be new body (A6 Chassis) and common rail engine from the '09 model.
My 1999.5 model Golf TDI was totalled in a accident in December and I now drive a 2009 Jetta TDI sedan. The common rail engine is fantastic but it's a complex piece of equipment. Only time will tell whether it's going to be reliable or not. I'm just now at 10,000 miles.
Fowvay, that is great and concise info. Thanks!
