Audi Repair Questions? Ask a Mechanic for Answers ASAP
There are sensors on the l/f and l/r of the lower control arms. It sounds like one of those is broken or water has got into the connectors. Do both headlights aim low? Is the suspension warning light on? You can look under both the front and rear of car on the left side and see if the rods are broken to the sensors mounted on the body.
Thank you for your reply. Both headlights aim low. The suspension warning light is NOT on, just the DHDC light. When I looked under the vehicle I did not see anything broken, but I am unsure if I looked in the right place. Should it be a sensor, can I order/ replace it myself - the nearest dealership is quite a ways from here!
On the ft. suspension there is a short plastic linkage attached to the front straight control arm. In the rear it is attached to the lower control arm, but it is a bit harder to see. There is a fault memory for the headlights, usually if there is a problem with the sensors than a suspension light comes on. I would suspect the back sensor is reading like the rear is loaded down causing the head lights to aim lower. Turn off the level suspension by pushing both the raise and lower buttons at the same time until they light up and raise the rear of the car and look at the l/r suspension sensor.
I have checked all sensors and the plastic linkages are intakt and the sensor electrics are hooked up - what to do?
