038906019AM VW Volkswagen Engine ECU Control Module – OEM Used & Tested

Açıklama

This listing is for OEM part 038906019AM — a genuine used, tested Engine ECU Control Module from the Volkswagen 038-series TDI diesel management family, covering a range of VAG Group models fitted with 1.9 TDI engines. Produced to original factory specification, this unit was recovered from a written-off donor vehicle and tested before being offered for sale.

The 038-series ECU controls the injection timing and quantity strategies for the 1.9 TDI pump-injector or common rail system, managing turbocharger boost via a variable geometry actuator, EGR valve operation for emissions compliance, and altitude correction of the fuelling map. It communicates with the gearbox ECU and ABS module via the CAN bus network.

A degrading 038-series ECU may produce a pronounced power loss at higher revs, repeated limp mode activation under motorway loads, erratic idle speed with a diesel knock at warm idle, fault codes for EGR and boost pressure deviation, or an inability to complete a DPF regeneration cycle. Cold-start smoke that clears slowly can also point to ECU injection timing issues.

Sourced from a written-off VAG Group vehicle and tested against the 038906019AM OEM specification, this unit is ready for professional fitting. VAG-compatible diagnostic software is required for coding after installation. Returns are accepted within 14 days of delivery, provided the unit has not been programmed or modified.
