Frequently Asked Questions

What is 4M0907561?

4M0907561 is an Audi cruise control distance sensor / ACC radar sensor used in compatible Audi driver assistance systems.

Which Audi models use 4M0907561?

The 4M0907561 sensor family is used on compatible Audi Q7, SQ7, Q8, SQ8 and RS Q8 applications. Exact compatibility depends on the OE suffix and vehicle configuration.

Is 4M0907561Q compatible with my Audi Q8?

It may be, but compatibility should be confirmed using the VIN and original sensor number. Audi lists 4M0907561Q for specific Q8 applications, so the suffix and production date matter.

What is the difference between 4M0907561P and 4M0907561S?

The parts catalog identifies 4M0907561S as replacing 4M0907561P for certain 2021–2025 applications. However, replacement should still be confirmed against the vehicle VIN and original configuration.

Does this sensor add Adaptive Cruise Control?

No. The sensor is only one component of the ACC system.

A complete ACC retrofit may require additional radar hardware, brackets, wiring, control units, steering-wheel controls, coding and calibration.

Does the radar sensor need coding?

Yes, coding or adaptation may be required after installation.

Component Protection may also need to be removed on applicable vehicles.

Does the radar sensor need calibration?

Depending on the vehicle and repair procedure, radar calibration / basic settings may be required after installation.

Can I install this sensor myself?

Professional installation is recommended because the sensor is part of a safety-related driver assistance system. Proper coding and calibration are important for correct operation.

Is the mounting bracket included?

This listing is for the ACC radar sensor/control unit. Mounting hardware and brackets are not automatically included unless specifically selected in the product option.

How can I confirm the correct sensor?

Send us:

• VIN
• Original ACC radar sensor part number
• Photo of the original sensor label
• Audi model and model year

We can check the available 4M0907561 suffix before you place the order.

Is the sensor tested before shipping?

Yes. The product listing states that the delivered hardware is functionally tested before shipment.

 

Technical specifications:

Volkswagen and Audi Parts Protection and Coding Notice:
For some Volkswagen and Audi control modules, component protection (CP) and coding need to be removed after installation.
Removing component protection (CP) and encoding involves advanced online authorization and firmware /EEPROM write procedures, which must be performed using the official factory diagnostic system.

By purchasing this product, the customer explicitly acknowledges and agrees:

1. Removing component protection (CP) and encoding poses irreversible risks.
2. Incorrect programs, software mismatch, unstable voltage, session interruption or unauthorized tools may all cause the module to fail to be recognized, resulting in communication interruption or the module being unusable.
3. The Seller shall not be held responsible for any damage, malfunction, loss of communication or failure resulting from the removal of component protection (CP), coding, programming or vehicle system adaptation by the customer or any third party (including Audi dealers, workshops, modifiers or mechanics).
4. Any malfunction that occurs after the removal of component protection (CP) and coding is regarded as third-party technical damage after delivery and does not constitute a manufacturing defect. It does not meet the conditions for return, refund or replacement.
5. Special Note: If the customer requests the seller to remotely flash data and code for product coding and to remove component protection, please contact in advance. The remote cost will be calculated separately (the seller is responsible for any damage caused by this remote flashing of data and code).
