Parts for your 2013 Audi Q5-Temperature sensors

2013 Audi Q5 temperature sensors

Yes — temperature sensors are absolutely fitted to the 2013 Audi Q5 and are essential to its engine management, climate control and emissions systems. Audi’s factory workshop information for the Q5 (8R) documents multiple sensors, including the Engine Coolant Temperature sender (often designated G62), Intake Air Temperature (G42, frequently integrated with the MAF), Ambient Air Temperature for the HVAC (G17), A/C refrigerant pressure/temperature, transmission fluid temperature on auto models, and—on diesel variants—several Exhaust Gas Temperature sensors upstream and downstream of the turbo and DPF. These are described in Audi’s ElsaWin/Workshop Manual and Self‑Study Programmes for the 2.0 TFSI and 3.0 TDI engines, and are listed in OEM parts catalogues (e.g., ETKA) under the Q5 (8R) platform.

On a 2013 Audi Q5, temperature sensors are the quiet achievers. They constantly feed data to the car’s control units so the engine, gearbox and climate control can make smart, split‑second decisions. The coolant temperature sensor tells the ECU how warm the engine is, shaping cold‑start enrichment, ignition timing and when the thermo fans kick in. Intake air temperature helps fine‑tune fuelling and boost, while the ambient sensor keeps the A/C behaving just right in Aussie heat or a chilly Kiwi morning. Automatic transmissions monitor fluid temp for shift quality and protection. Diesel models rely on exhaust gas temperature sensors to protect the turbo and manage DPF regeneration without drama.

As part of regular servicing, it’s wise to keep an eye on temperature‑sensor health. They’re solid‑state devices, but age, heat cycles, coolant contamination or connector corrosion can cause drift or failure. Telltales include hard cold starts, rich running, a lazy temperature gauge, radiator fans roaring when they shouldn’t, weak A/C performance, or the MIL glowing with codes like P0116–P0119. If there’s any doubt, a quick scan with live data is gold—compare reported temperatures to reality on a cold start (they should all read close to ambient) and after warm‑up (coolant typically in the 85–105°C range).

Replacement is usually straightforward: depressurise and drain enough coolant if needed, unplug, swap the sensor and O‑ring, then refill and bleed the cooling system. Use genuine‑quality parts, fresh coolant to Audi spec, and clean electrical connectors with dielectric grease. Most sensors don’t need coding, just clear fault codes and verify readings. For diesels, ensure any EGT sensor wiring is routed and clipped exactly as from factory—those harnesses live in hot places and don’t like shortcuts. With a little attention each service, the Q5’s temperature sensors help it run sweet as for many more kilometres.

• Watch for erratic temp readings, unexpected fan operation, rising fuel use or A/C performance drops.
• Check live data at each major service and when coolant work is done.
• Replace seals/O‑rings and bleed coolant carefully to avoid air pockets.

Popular questions about 2013 Audi Q5 temperature sensors

How many temperature sensors does a 2013 Audi Q5 have?
There isn’t a single number for all trims, but expect several: engine coolant temperature, intake air temperature, ambient air temperature, A/C refrigerant pressure/temperature, and transmission fluid temperature on autos. Diesel Q5s also add multiple exhaust gas temperature sensors for turbo and DPF management.

What are common signs a coolant temperature sensor is failing?
Cold‑start hiccups, rough idle, poor fuel economy, an overactive radiator fan, a sluggish or jumpy temperature gauge, and fault codes like P0116–P0119 are typical. Live data that doesn’t match the actual ambient temperature on a cold engine is another giveaway.

Do new temperature sensors need coding or calibration?
Most do not. After fitting, clear any stored codes, bleed the cooling system if applicable, and confirm live readings. Certain diesel exhaust temperature sensors may require a basic settings check, but coding is rarely needed.
