2013 TDI Diesel with a P2196 engine code. The Passat only has 51,000 miles on it.

Question

Could a clogged fuel filter cause the P2196 code to come up?  The engine seems to run fine.  No rough idle.  I know the fuel filter needs to be changed.

Answer 1

This code indicates an issue with the O2 sensor bank 1 sensor 1. Here is a list of possible causes.
