Description:The height sensor is an electronic device that measures the distance between the road and a particular point on the vehicle's suspension, chassis or body.Based on the output of the sensor, the Engine Control Unit (ECU) makes the compressor determine whether to fill or release air from the air bags.The height sensor sends signals to the ECU, which causes the suspension to react while driving over bumps or due to heavy loads on the vehicle to provide a smoother ride.This is a non-OEM product, accessory only!Specifications:Material: MetalSize: 16x14.3cm / 6.30"x5.63"(L*W)OE Number: 1K0941273LPin Number: 4Color: BlackFitment:for Audi A3 2.0L A/T Base Hatchback 2009-2013for Audi A3 2.0L A/T Quattro Base Hatchback 2009-2013for Audi A3 2.0L M/T Base Hatchback 2009-2013for Audi A3 2.
