BOSCH D MAP Sensor 4 BAR for VW 1,9 TDI (1Z, AHU, ALE, AGR, ALH, AFN, ASV) 2,5 TDI AEL - 0281006059

Key Features & Benefits – BOSCH D-MAP sensor 4 bar

The BOSCH D-MAP sensor 4 bar is used for intake pressure and temperature measurement. The stated application targets VW 1.9 TDI (1Z, AHU, ALE, AGR, ALH, AFN, ASV) and 2.5 TDI (AEL) engines. For functional compatibility, it suits setups where the original sensor shares the same part number and matching connector/mounting.

It is recommended for TDI tuning when a 4 bar MAP sensor is required for boost pressure measurement and the ECU calibration matches the sensor signal. Note: this type is counterfeited, avoid suspiciously low-priced offers.

When is this useful?

This is useful when you need the same part-number sensor for factory applications on 1.9 TDI or 2.5 TDI setups, or when a TDI/PD TDI build requires a 4 bar MAP sensor for boost pressure measurement.

Selection & installation tips

• Part number check: confirm your original sensor part number matches, or your setup is built around this exact type.
• Connector & mounting: compare connector layout and mounting points against your existing sensor.
• Pressure range: make sure ECU maps are calibrated for a 4 bar sensor signal.
• Sealing: verify charge pipe/intake connections are leak-free, as leaks can skew readings.
• Authenticity check: since it is counterfeited, inspect markings and build quality and avoid unusually cheap offers.

Before fitting, verify the part number, connector and mounting match, and that your ECU calibration supports a 4 bar sensor, then compare those checks to the compatibility details listed above.
