BRAND NEW *OEM Quality* 3-Bar MAP sensor (Manifold Absolute Pressure) to suit Audi Q5 and Q7 with V6 V8 and V12 TDI diesel engines.

Boost loss and limp mode on a large-displacement Audi diesel are unmistakable - the difference in power is dramatic compared to smaller engines. This MAP sensor directly replaces OEM 038906051C on Q5 and Q7 models and restores correct boost management. Dispatched same-day from Melbourne.

TO SUIT

Suits Audi Q5 8R with 3.0L V6 TDI (CAPA CCMA CLAA CASA) and Q7 4L with 3.0 V6 TDI and 4.2 V8 TDI (CDSB CCDT). The Q7 6.0L V12 TDI (CJMA) is also covered - this engine runs twin turbos in series and the MAP sensor monitors post-intercooler pressure after the second stage. Failure on the V12 TDI commonly produces P0105 alongside turbo-specific codes and defaults the vehicle to a single-turbo safe mode. Confirm OEM 038906051C matches your part before ordering.

ABOUT THIS SENSOR

On V6 and V8 TDI Q-series engines the MAP sensor monitors intercooler outlet pressure to help the ECU calibrate fuel delivery across a wide boost range. At higher displacement a single incorrect pressure reading causes larger fuelling errors and more noticeable power loss than on 4-cylinder variants.

The Q7 V12 TDI is particularly affected - twin turbos in series mean the MAP sensor reading influences two stages of boost control. A failing sensor on the V12 TDI often produces reduced towing performance and highway limp mode before any fault codes appear on simpler scan tools.

COMMON SYMPTOMS OF FAILURE

Fault codes P0105 P0107 P0108 with EML
Severe limp mode on V8 and V12 TDI - engine restricted to low boost
Poor acceleration from a standing start under load
Increased exhaust smoke (black) under hard acceleration
Reduced towing capacity or trailer sway at speed
Fuel consumption increase of 15-20% in V6 TDI

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.
