Ride Height Sensor – Front & Rear Left & Right – Audi – 4B0907503A
Overview What this part does
Get your Audi back to proper headlight beam alignment and air suspension control with this replacement ride height level sensor, also referenced in service manuals as the suspension level sensor or air suspension sensor. Built to OEM specification, matching 0901269, 0901196, 4B0907503 and 4B0907503A.
Common signs of failure
A failing ride height sensor commonly causes xenon, LED or matrix headlights to point too high (dazzling oncoming drivers) or too low (reducing your night-time visibility), and often disables auto-levelling entirely. On VAG group cars expect dashboard headlight error messages and fault codes B106A or B107A; on cars with air suspension you'll see the suspension warning light, uneven ride height, or the vehicle stuck low after parking. Faulty sensors also cause MOT fails on the headlamp aim test.
Fitment notes
Plug-and-play installation, no diagnostic coding required. The same physical sensor is shared across the VAG group (Audi, VW, Skoda, Seat) on many platforms — the quickest way to confirm fit is to match your existing part number to one of those listed above. Mounting bracket and linkage are typically reused from your original sensor. Standard 4 pin connector. Position: Front, Left, Rear.
Frequently asked questions
Is this a headlight sensor or an air suspension sensor?
Same physical part — most VAG group cars use one sensor whose signal feeds both the auto-levelling headlight ECU and (where fitted) the air suspension control module. Replacing it fixes both systems.
Will replacing it stop the dashboard warning?
Yes — once the new sensor is fitted and the ignition cycled, headlight error messages usually clear on their own. Stubborn faults can be cleared with VCDS or any generic OBD2 scanner that supports module reset.
Do I need to calibrate the headlamps after fitting?
Basic aim adjustment is recommended after replacement; full electronic calibration is only required if the headlamp unit itself was also replaced.
