T4 Air Mass Meter - 1998-00 - 2.5 TDI (ACV,AJT,AUF)

This replacement air mass meter (also known as a MAF sensor) is designed for Volkswagen Transporter T4 models equipped with 2.5 TDI engines, specifically engine codes ACV, AJT, or AUF, built between May 1998 and August 2000.

The air mass meter plays a vital role in engine performance and fuel economy. It measures the amount of air entering the intake system and sends this data to the engine control unit (ECU), which then adjusts the fuel injection accordingly. A faulty MAF sensor can lead to poor throttle response, black smoke, loss of power, or increased fuel consumption. Replacing it can quickly restore proper engine operation.

This unit includes 5 electrical terminals and comes complete with the housing, making it a direct plug-and-play replacement for the original part. No need to reuse your old housing or risk damage during sensor-only swaps — this all-in-one assembly ensures proper alignment, sealing, and long-lasting operation.

Compatibility:

• VW T4 Transporter 2.5 TDI with engine codes ACV, AJT, AUF

• Model Years: May 1998 – August 2000

Installation Tip:
Always disconnect the battery before installing electronic components. After fitting, clear any stored fault codes and allow the ECU to recalibrate for best performance.
