- Description:
6.3L. Listed under Audi part number 4H0-131-837-A, this Secondary Air Injection Pump Filter keeps the exhaust and evaporative streams within regulated limits, and because the engine management strategy adapts around these components, a degraded unit affects drivability as well as emissions compliance. Buying genuine keeps the vehicle's original fit, finish, and warranty coverage intact. Use the fitment guide or contact our parts team to confirm the correct application.

Key Product Information
Additional Information
| SYMPTOMS | Symptoms associated with a failing emissions component (4H0-131-837-A): a check engine lamp, failed emissions inspection, fuel smell around the vehicle, reduced power or a regeneration warning on diesel applications, or a rattle from a broken internal substrate. Confirm the complaint against the vehicle identification number and option content before ordering. |
| TROUBLESHOOTING | To confirm 4H0-131-837-A is the cause rather than a symptom: read freeze frame data along with the code, since an efficiency fault often traces back to an upstream misfire, oil consumption, or leak rather than the emissions component itself. A scan tool with Audi specific coverage will show considerably more than a generic code reader. |
| INSTALLATION | Correct installation of this emissions component (4H0-131-837-A) requires all upstream faults to be corrected first, otherwise the same condition that destroyed the original component will destroy the replacement. Allow for the published labor time and any post installation calibration or coding. |
| MAINTENANCE | Ongoing maintenance where 4H0-131-837-A is fitted means keeping the engine in good tune, using the correct fuel, and completing regeneration cycles rather than interrupting them on diesel applications. Use fluids and parts that meet the Audi specification for the vehicle. |
| GENERAL_NOTES | Key consideration for 4H0-131-837-A: emissions components are federally regulated and may carry a separate warranty period from the balance of the vehicle. Availability and part number supersession can change, so confirm the current number when ordering. |
| FAULT_CODES | Fault codes commonly stored when this component fails, applicable to part 4H0-131-837-A: P0410 through P0419 for secondary air injection system faults, including P0411 for incorrect flow detected and P0491 or P0492 for insufficient flow by bank. |
| REPLACEMENTS | Commonly replaced alongside 4H0-131-837-A: gaskets, clamps, hangers, and affected oxygen sensors are renewed with the component to guarantee a sealed, leak free installation. Replacing wear items together restores the assembly to its original condition. |
