I have been driving around with 'Air Suspension Inactive' error for the last 15000 or so miles. Had it reset a couple of times while car was in garage for other repairs, fault always comes back after a week or two.

Mechanic showed me testbook while connected, and showed compressor operating but not reaching the required pressure within the specified time, causing a static pressure error. Pressure climbed pretty quickly but levelled off and rose very slowly after that.

Have decided to get it sorted at last, and I'm going to try changing the resevoir pressure sensor first, as compressor has lasted this long without throwing it's hand in.

Has anyone changed this sensor? How do I drain the resevoir in order to do this? If you like it, who cares what other people think

Dear sir, correct way! I have changed some sensors, very easy, climbe under your car, right side, under the back door near the wheel, look, there is a graet plastic-cover under the car, open the screws, and press the plastic down, you can reach the sensor, first you must let out the air, it is shown in a youtube video from the good "old" Storey Wilson RSW Solutions, when the pressure is out, change it slowly, than fill the reservoir with your compressor, but normalywise the compressor will bb the next step..., decide for your own.

Thanks Meerbusch, going to order sensor today and will give update when I get round to changing it.
