BRAND NEW *OEM Quality* 2.5 Bar boost pressure sensor to suit Bentley Continental GT and Flying Spur 3W with 6.0L W12 twin-turbo engine.

Bentley Continental MAP sensor failure is uncommon but when it happens the W12 twin-turbo response is affected. This sensor is an exact OEM-spec replacement for 038906051B used across the 3W Continental platform. Dispatched from Cranbourne VIC.

TO SUIT

Suits Bentley Continental GT 3W and Continental Flying Spur 3W with 6.0L W12 twin-turbo engine from 2005 to 2015. The Continental 3W uses twin parallel turbos feeding a common intercooler - this MAP sensor monitors post-intercooler pressure for both banks. The W12 engine shares sensor architecture with Volkswagen Group TFSI/TDI platforms. Confirm OEM 038906051B matches your existing sensor before ordering.

ABOUT THIS SENSOR

The Bentley Continental W12 is fundamentally built on Volkswagen Group platform architecture. The MAP sensor used on the W12 is identical in specification to the sensor used on smaller-displacement VAG engines - the 2.5 Bar range is more than adequate for the Continental's boost targets across both turbochargers.

On the W12 platform MAP sensor drift rather than outright failure is the typical failure mode. The sensor slowly reads low which causes the ECU to add extra fuel - this produces a characteristic slight richness on idle and marginal smoke on cold start that owners sometimes dismiss as normal W12 behaviour before fault codes eventually appear.

COMMON SYMPTOMS OF FAILURE

Fault codes P0105 P0107 P0108 stored in ECU
Subtle richness at idle and slight smoke on cold start
Marginal reduction in peak throttle response
Increased fuel consumption at highway cruising
EML with no obvious driving symptom in early stages
Boost asymmetry codes if sensor reads inconsistently between banks

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.
