What is the code P2BA6 on a VW Jetta TDI?
Jetta TDI often faces EGR flow problems and diesel particulate filter efficiency drops causing emissions faults. The P2BA6 code indicates SCR NOx catalyst underperformance, often due to catalyst degradation or sensor faults. EGR insufficient flow and slow response suggest clogged EGR valves or passages.

What is the code P026A on a Jetta TDI?
The P026A code signifies that the air is not being adequately cooled in the intercooler before it reaches the engine. This issue is often due to a dirty, obstructed, or faulty intercooler. Code P262B indicates a problem with the camshaft position actuator circuit, often due to a faulty camshaft actuator solenoid or wiring issues. Symptoms include the check engine light staying on and potential rough idling. This fault can affect emissions by disrupting valve timing.
