2014 Audi Q5 Camshaft Position Sensor – Purpose, Fitment and Servicing Advice

Yes, the 2014 Audi Q5 uses a camshaft position sensor (often called a CMP or “cam sensor”). This is documented in Audi’s Elsa/Erwin workshop information and the Volkswagen Group ETKA parts catalogue, which list a camshaft position sender for the 2.0 TFSI and 2.0 TDI engines (commonly designated G40), and two camshaft position senders for the 3.0 TFSI and 3.0 TDI V6 engines—one per cylinder bank (commonly designated G300 and G301). VAG Self‑Study Programmes for the EA888 four‑cylinder and EA837/EA897 V6 engines also describe Hall‑effect camshaft sensing as part of variable valve timing and engine management. Typical OBD‑II diagnostics for this model include camshaft sensor‑related DTCs (e.g., P0340/P0341), further confirming fitment.

On the Q5, the camshaft sensor’s job is to tell the ECU exactly where the cam is in relation to the crank. That lets the ECU time fuel injection and spark precisely, manage variable valve timing, and deliver clean cold starts. Without a clean cam signal, the engine can crank longer, run rough, lose power, or drop into limp mode. Fuel economy and emissions also take a hit.

There’s no scheduled maintenance specifically for the cam sensor, but as part of regular servicing it’s smart to:

• Inspect the sensor connector and wiring for chafing, oil ingress, or brittle insulation.
• Check for oil leaks at the rocker/valve covers that could wick into the plug.
• Scan for stored or pending DTCs after any drivability complaint, rough idle, or hard start.

Replacement is straightforward for a trained tech. Use the correct-spec Hall‑effect sensor, fit a new O‑ring if applicable, and torque the retaining fastener to the workshop manual spec. After installation, clear fault codes and perform any required basic settings or adaptations with a compatible scan tool. On the V6, confirm which bank is faulting, both banks have their own sensor and signals must agree. Location-wise, expect the sensor near the end of the cam at the cylinder head—on the four‑cylinder typically at the rear under the engine cover, and on the V6 one per bank near the cam cover.

Common symptoms that point to a crook cam sensor on a 2014 Q5 include:

• Extended cranking or no start when hot or cold
• Hesitation, misfires, or poor throttle response
• Erratic idle, reduced power, or limp-home mode
• Check Engine Light with cam correlation codes

Because the sensor is critical to synchronisation, don’t ignore early signs. A quick diagnosis can save time, fuel, and unnecessary parts swaps.

Does a 2014 Audi Q5 have more than one camshaft sensor?

It depends on the engine. The 2.0 TFSI and 2.0 TDI generally use a single camshaft position sensor. The 3.0 TFSI and 3.0 TDI V6 engines have two—one per bank. Fault codes and wiring diagrams in the factory manual identify which bank is affected.

Where is the camshaft sensor on a 2014 Q5?

On the four‑cylinder, it’s usually at the end of the cam near the rear of the head under the top cover. On V6 models, there’s one on each cylinder bank near the cam covers. Access varies, so removing the engine cover and a few intake bits may be required.

Should the camshaft sensor be replaced during routine servicing?

It’s not a scheduled replacement item. Replace it if there are confirmed fault codes, symptoms, or physical damage. During servicing, a quick visual check of the connector and wiring, plus a scan for stored faults, is good practice.
