BRAND NEW *OEM Quality* 2.5 Bar boost pressure sensor to suit Volkswagen Transporter T5 and Caravelle with 1.9L and 2.5L TDI diesel.

The Transporter T5 TDI is a working vehicle and MAP sensor failure in a commercial fleet means lost productivity. This OEM-spec replacement covers all T5 1.9L and 2.5L TDI diesel applications. Dispatched same-day from Melbourne.

TO SUIT

Suits Volkswagen Transporter T5 including Caravelle and Multivan with 1.9L TDI (AXB AXC BRR BRS) and 2.5L R5 TDI (AXD AXE BNZ BPC) from 2003 to 2015. The 1.9 TDI single-turbo variant is the highest volume application. The 2.5 R5 TDI uses a sequential twin-turbo system - a faulty MAP sensor on this engine prevents the second turbo engaging under load causing a van that feels fine around town but struggles badly when fully laden on the highway. Confirm OEM 038906051B before ordering.

ABOUT THIS SENSOR

The Transporter T5 1.9 TDI operates in one of the most demanding sensor environments in the VW range. Long idling periods during delivery rounds and high EGR flow rates on the AXB and AXC engines can contaminate the MAP sensor with oily deposits far faster than in passenger cars. Many T5 TDI fleet operators replace the MAP sensor as preventative maintenance at 100000 km intervals to avoid roadside failures.

On the 2.5 R5 TDI with twin turbos MAP sensor accuracy is critical for managing the switch between low-load single-turbo and high-load twin-turbo mode. Unlike the 1.9 TDI where limp mode is the first symptom the 2.5 TDI often shows as a very specific failure - insufficient power when fully laden on the highway while performing normally when unladen around town.

COMMON SYMPTOMS OF FAILURE

Fault codes P0105 P0107 P0108 on OBD2 scan
Limp mode when van is fully loaded or towing
Second turbo not engaging on 2.5 R5 TDI at highway speed
Black smoke on hard acceleration
Poor cold start on 1.9 TDI in winter
Increased fuel consumption on long highway runs

What fault codes does a faulty MAP sensor trigger?

A faulty MAP sensor typically triggers codes P0105 to P0109. P0105 indicates a circuit malfunction, P0106 indicates the signal is out of range, P0107 and P0108 indicate the signal is too low or too high respectively, and P0109 indicates an intermittent circuit fault. These codes combined with symptoms such as poor idle and black smoke are strong indicators of MAP sensor failure.

How do I test a MAP sensor?

With an OBD2 scanner in live data mode, the MAP sensor should read close to atmospheric pressure (around 101 kPa) with the engine off, and drop to 30 to 50 kPa at idle with the engine running due to manifold vacuum. Under wide open throttle the reading should rise back toward atmospheric. A sensor that reads flat or does not respond to throttle changes has failed. You can also test supply voltage and signal output with a multimeter.

Can I drive with a faulty MAP sensor?

You can drive short distances but engine performance will be noticeably degraded. The ECU uses the MAP sensor to calculate fuel delivery - a faulty sensor causes incorrect fuelling which leads to poor economy, rough running, and increased emissions. On turbocharged engines a faulty MAP sensor can also prevent boost control from operating correctly. Replace it as soon as possible to avoid further damage.

What does a MAP sensor do?

The Manifold Absolute Pressure (MAP) sensor measures intake manifold pressure to help the ECU calculate the correct fuel and ignition timing. It is critical for engine efficiency, particularly on turbocharged and supercharged vehicles.

What are the symptoms of a faulty MAP sensor?

Symptoms include poor acceleration, rough idle, excessive fuel consumption, black smoke, engine hesitation, and a Check Engine light with codes P0105-P0109. Turbocharged vehicles may also experience boost control issues.

What is the difference between a MAP sensor and a MAF sensor?

A MAF (Mass Air Flow) sensor directly measures the mass of air entering the engine. A MAP sensor measures manifold pressure and the ECU calculates air mass from that reading. Many vehicles use one or the other; some use both. They are not interchangeable.
