The 2009-2010 Jetta TDI shared the same body and chassis – the A5 chassis – with all Jettas since 2005.5, which was also referred to as the MkV Jetta. The 2009 release of the 2.0L, Common Rail powered TDI diesel engine marked the first common rail diesel that VW released in the US, and its first diesel since the 2006 Jetta TDI.
Engine
Often referred to by VW personnel and advertisements as the Jetta “Clean Diesel”, the 2009 diesel marked many important milestones in the history of diesel engined vehicles in the US. Firstly, it was the first TDI since 2003 that was 50-state approved. It also marked the first VW passenger vehicle to use a diesel particulate filter, or DPF. Most importantly, it was the first North American Volkskwagen to utilize “common rail” style injection.
Unlike the VW-pioneered Pumpe Duese system, in the common rail type system one high pressure pump supplies one main injection line, or rail, which goes to all injectors. This main rail is pressurized by the high pressure pump to somewhere around 30,000 psi. This extreme high pressure allows better fuel injection, meaning more power and more efficiency in addition to lower emissions when mated with a DPF.
The 2009-2010 Jetta TDI is powered by a 2.0 liter, 4 cylinder turbocharged diesel engine.
