Detailed Product Information

Standard Ignition ALH310 is engineered as a body wiring harness component for the antilock brake system. It is listed for 2009-2017 Audi Q5 rear left, w/o Electronic Suspension, and 2014-2017 Audi SQ5 rear left, w/o Electronic Suspension. This part cross-references 8R0972253 and ABH310 for the same application. If you are servicing an Audi Q5 rear left ABS wheel speed sensor wiring harness or replacing a damaged Audi SQ5 rear left sensor lead, ALH310 provides the specified connector layout and terminal configuration for the vehicle-side repair.

Common Problems This Part Addresses

• Broken or frayed wheel speed sensor wiring at the rear left corner
• Intermittent ABS warning light caused by poor sensor signal continuity
• Corrosion or connector damage at the sensor harness connection
• Fault codes related to wheel speed sensor circuit interruption
• Loss of stable antilock brake system input from the rear left wheel

Installation Notes and Tips

Verify the vehicle is equipped without Electronic Suspension before ordering. Confirm rear left routing, connector shape, and terminal style against the original harness before installation. Inspect the sensor, connector pins, and nearby wiring for damage or corrosion so the replacement harness is not installed over an unresolved fault. Standard Ignition ALH310 should be matched to the listed Audi Q5 and Audi SQ5 fitment by year and position.
