❓ Frequently Asked Questions

1. What does a rear height level sensor do?
   This sensor measures the distance between the vehicle’s chassis and the road surface at the rear. It sends this information to the suspension control unit (or headlight control unit), which uses the data to maintain correct suspension height and adjust the headlight beam if needed.

2. Which models is this sensor compatible with?
   It fits several Audi models — including A6, A6 Allroad, A7, A8, Q5 — and Porsche Macan with the appropriate ride-height or air-suspension systems.

3. Is this an OEM or aftermarket part?
   This is a high-quality aftermarket replacement sensor. At DDP AutoParts, we source sensors that match OEM performance so you don’t have to pay OEM-level prices.

4. What are the common symptoms of a failing height level sensor?

   • Suspension warning light or “level system” fault on the dashboard.

   • Car not maintaining correct ride height (sagging or riding too high).

   • Headlights mis-level automatically or don’t adjust properly (in cars with auto-levelling).

   • Air suspension issues (if equipped), e.g., compressor overworks or doesn’t maintain pressure.

5. How difficult is it to replace? Do I need to recalibrate after fitting?

   • Replacement usually involves unbolting the old sensor from the suspension arm and connecting the plug.

   • After fitting, you may need to recalibrate or “teach” the height sensor using diagnostic software (OBD-II, VCDS, or similar) so that the control module reads the correct zero position. Several Audi users report this step is necessary to prevent incorrect readings.

   • If calibration isn’t done, it can lead to suspension faults or incorrect ride height behaviour.

6. Is this sensor exposed to damage?
   Yes. It’s located on the suspension arm, and can be damaged by road debris, corrosion, or mechanical stress.

7. Does DDP AutoParts provide a warranty or return on this sensor?
   Yes — we offer our standard parts warranty. If the sensor is faulty or doesn’t fit, contact our support team and we’ll guide you through testing, replacement, or return.
