AUTOKAY Engine Cooling Fan Control Module for Audi A4/A5/Q3/Q5 — Direct-Fit Replacement, OE-Compatible

AUTOKAY Engine Cooling Fan Control Module is a direct-fit replacement controller that manages radiator fan speeds for compatible Audi models, restoring proper cooling system operation.

This control module replaces worn or faulty fan electronics to help your Audi’s cooling fans respond correctly to engine temperature and HVAC demands. Engineered to match the fit and electrical specifications of several Audi OE part numbers, the AUTOKAY module offers an affordable swap-in option for technicians and DIYers who need reliable thermal regulation without custom wiring or programming.

• SUV fitment: Audi Q3 (2015–2018), Q3 Quattro (2015–2018), Q5 (2010–2017), allroad (2013–2016).
• Other fits: Audi A6/A6 Quattro (2012–2017) and A7 Quattro 3.0L (2014–2016) when that chassis used the same controller design.
• Engine types covered: I4 2.0L engines and select V6 3.0L where specified.

How does replacing the fan control module help my car?

A failing fan control module can cause fans to run constantly, not run at all, or operate intermittently—leading to overheating, reduced HVAC performance, or abnormal electrical loads. Installing a correctly matched replacement restores proper fan logic so the vehicle’s cooling and climate systems behave as designed.

• Restores automatic fan speed control tied to coolant temperature sensors and A/C demands.
• Reduces the risk of overheating from non-operational or stuck fans.
• Eliminates erratic fan behavior that can trigger fault codes or dash warnings.
• Plug-and-play electrical fitment for simpler installation with OEM connectors.

What are the key specifications and included items?

The AUTOKAY module is supplied as a single replacement unit matched to common Audi replacement part numbers for straightforward swapping. It’s produced to meet electrical interface and mounting points typical of the original equipment so installers can expect minimal modification.

• Replace part numbers covered: 8K0959501A, 8K0959501C, 8K0959501G, 8K0910501D.
• Package contents: one (1) engine cooling fan control module ready for installation.
• Designed for direct electrical connector compatibility with referenced Audi models.
• Durable housing to protect electronics from engine-bay exposure.

How difficult is installation and what should I check first?

Installation difficulty is moderate: accessible to a skilled DIYer with basic hand tools, but verification steps are important to avoid unnecessary replacement. Check wiring condition and fuse/relay health before swapping modules to isolate the controller as the fault source.

• Inspect connectors and wiring for corrosion, breaks, or heat damage before replacing the module.
• Scan for related diagnostic trouble codes to confirm fan-controller faults.
• Ensure the replacement part number matches your vehicle’s original controller reference.
• Re-test fan operation and clear codes after installation to confirm resolution.

Who is this for: The AUTOKAY Engine Cooling Fan Control Module is intended for Audi owners, independent mechanics, and service shops handling cooling system faults on mid‑2010s Audi A‑series and Q‑series vehicles. If your Audi shows fan-related errors, abnormal fan behavior, or cooling performance issues and the diagnostics point to the controller, this unit provides a cost-effective, direct-replacement option when matched to the correct part numbers.
