The data indicates that the majority of Volkswagen Jetta (2011-19) 4-door saloons with the specified engine code and features were manufactured in 2012, accounting for 43.1% of the sample. The next most common year is 2013, representing 25%, followed by 2011 at 18.1%, and 2014 at 13.9%. Notably, over 80% of these vehicles are from 2012 and 2013, suggesting these model years are the most prevalent in the used market. This could reflect manufacturing focus or market demand during those years.

The data indicates that all Volkswagen Jetta models in the 2011-2019 range with the specified description are equipped with a 1.6-liter engine capacity and run exclusively on diesel fuel. This suggests a uniformity in engine size and fuel type for this particular vehicle variant, which could be relevant for buyers interested in this specific configuration or for assessing vehicle specifications in this category.
