Where is the oil filter in a VW T4 2.5TDi?

In a VW T4 2.5 TDi, the oil filter is located on the front side of the engine, just above the oil pan. To access it, you may need to remove the engine cover and possibly the air intake duct for better visibility and reach. The filter itself is a cylindrical metal component, typically positioned horizontally. Make sure to drain the oil and replace the filter with the correct type during maintenance.
