CJAA EGR Valve 03L131501F

03L131501F

03L131501F is an OEM Exhaust Gas Recirculation (EGR) Valve, a critical emission control component for 2.0L TDI (diesel) engines

This electric control valve is typically located on the EGR cooler. It functions by recirculating small amounts of cooled exhaust gases back into the engine's intake manifold. This process lowers combustion temperatures, which significantly reduces the formation of smog-producing nitrogen oxides (NOx) and improves overall combustion efficiency. 

This valve fits several Volkswagen and Audi models, primarily with the 2.0L TDI engine (engine codes such as CBEA and CJAA): 
Volkswagen:
Golf / Golf Wagon: 2010–2014
Jetta / Jetta Wagon: 2009–2014
Beetle / Beetle Convertible: 2013–2014
Passat: 2012–2014
Audi:
A3 TDI: 2010–2013
