Arnott RH-5042 Headlight Level Sensor - Front Right

Front Right Headlight Level Sensor for Audi

Arnott RH-5042 is a new front right headlight level sensor for Audi models equipped with electronic struts. It reads chassis-to-road distance and sends that data to the ECU so the suspension system can adjust air pressure as needed. This helps maintain proper vehicle leveling and supports consistent headlight aim on Audi A4, A4 Quattro, A5, A5 Quattro, S4, S5, and RS5 applications.

Detailed Description

Arnott RH-5042 is an aftermarket ride height sensor built for Audi suspension systems that use electronic struts. By measuring the distance between the chassis and the road, the sensor provides input to the ECU, which then commands the air suspension compressor to raise or lower air pressure in the air struts. This function supports proper ride height control and headlight leveling on the front right side. This part cross-references OE-style part numbers 8K0941286H and 8K0941286N for the same application.

Compatible With 2008-2017 Audi A5 Quattro, front right; 2008-2017 Audi S5, front right; 2009-2016 Audi A4, front right; 2009-2016 Audi A4 Quattro, front right; 2008-2016 Audi A5, front right; 2013-2016 Audi RS5, front right; 2011 Audi RS5, front right; 2010-2016 Audi S4, front right.

What It Helps Address

• Incorrect headlight leveling on Audi vehicles with electronic struts
• Suspension height signal errors sent to the ECU
• Uneven or inconsistent front ride height readings
• Sensor wear from road debris, water, salt, or impact damage
• Air suspension control issues caused by a failing ride height sensor

Installation Notes and Tips

Verify front right placement and connector style before installation. Confirm the vehicle is equipped with electronic struts and match the OE reference numbers when comparing the original sensor. Inspect the mounting area for corrosion, debris, or damage that could affect sensor readings after replacement.

Quality Assurance
