BRAND NEW *OEM Quality* 3-Bar MAP sensor (Manifold Absolute Pressure) to suit Audi A1 A3 A4 A5 A6 A7 A8 Q2 Q3 Q5 Q7 RS3 S1 S3 TT with TFSI and TDI turbocharged engines.

A failed MAP sensor on your Audi will trigger codes P0105 P0107 or P0108 and typically pushes the engine into limp mode with noticeable boost loss. This direct-fit replacement restores accurate pressure sensing and clears the fault. Dispatched same-day from Cranbourne VIC.

TO SUIT

Suits Audi A3 8P and A4 B7/B8 running 2.0 TFSI (CAWB CDNB CDLC) and 2.0 TDI (CAGA CJCA CGLB) engines where MAP sensor failure is common. Also suits A5 Sportback and Q5 with 2.0 TFSI - the sensor sits downstream of the intercooler on all these platforms and is interchangeable. The Q7 and A6/A7/A8 with 3.0 TDI also share this fitment via OEM 038906051C. Verify your OEM number before ordering.

ABOUT THIS SENSOR

On Audi TFSI and TDI engines the MAP sensor is mounted on the intake manifold downstream of the turbocharger and intercooler. It measures boost pressure and sends that signal to the ECU which uses it to calculate injection quantity and boost control targets.

On the 2.0 TFSI platform the sensor is particularly vulnerable to oil contamination from the PCV breather system. Contamination degrades the internal diaphragm and causes the sensor to read low or erratically - often mimicking a boost or turbocharger fault before the true cause is identified.

COMMON SYMPTOMS OF FAILURE

Engine management light on with fault codes P0105 P0107 P0108
Engine enters limp mode with limited boost
Turbo lag or flat spot under acceleration
Poor fuel economy on TDI models
Black smoke on TDI under load
Rough idle on TSI/TFSI after cold start

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.
