Built to OEM specification, matching 3C0412521B and 3C0907503.\u003c\/p\u003e\n\u003ch3\u003eCommon signs of failure\u003c\/h3\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003ch3\u003eFitment notes\u003c\/h3\u003e\n\u003cp\u003ePlug-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. Position: Front, Left.\u003c\/p\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003ch4\u003eIs this a headlight sensor or an air suspension sensor?\u003c\/h4\u003e\n\u003cp\u003eSame 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.\u003c\/p\u003e\n\u003ch4\u003eWill replacing it stop the dashboard warning?\u003c\/h4\u003e\n\u003cp\u003eYes — 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.\u003c\/p\u003e\n\u003ch4\u003eDo I need to calibrate the headlamps after fitting?\u003c\/h4\u003e\n\u003cp\u003eBasic aim adjustment is recommended after replacement; full electronic calibration is only required if the headlamp unit itself was also replaced.\u003c\/p\u003e","brand":"PitShopUK","offers":[{"title":"Default Title","offer_id":57283593273688,"sku":"85","price":42.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/3373\/0136\/files\/SKU85_1_updated_e8782aa1-93ae-4ec9-9af2-6551de4e5630.jpg?v=1780868814","url":"https:\/\/carpartclubs.com\/products\/suspension-height-sensor-front-left-vw-touran-1t3-2010-15-3c0412521b","provider":"CarPartClubs","version":"1.0","type":"link"}
