wears over time causing these symptoms.
The piston ring within the compressor unit of your air suspension system deteriorates over time,

The following guide explains how toresolve these problems by installing our piston seal replacement kit available from X8R Ltd. For instructions guiding removal of the compressor from your vehicle please check out our other.
Using a T30 Torx remove head bolts and remove head. If the bolts are seized or appear rusty apply WD40 to the bolts and threads, allow time to work then remove bolts. On some vehicles there is a temperature sensor fitted on one of the head bolts; remove this and remember to refit when refitting head later on.Step 2: Replace sealRemove old seal from inside of head, clean groove and mating surfaces and replace with the correct seal from our kit, please note some compressors use an 0-ring seal others use a shaped seal, we include both in our set, you only need to use one of these. Check cylinder for any damage; the cylinder is tapered, check fordents or scratches these can significantly reduce the life of replacement piston seals.Step 3: Fit new piston sealNote position of existing piston ring and fitment around timing pin and remove ring. Clean piston and piston ring groove and fit new piston ring in the same position as the old ring; fitting around the timing pin, compress ring in hand to ensure correct operation.Step 4: Refit compressor headClean all mating surfaces and refit head. Install our new bolts applying a little lock tight to the threads.Refit temperature sensor if one was fitted.Step 5: Test compressor output
It is good practice to bench test the compressor before refitting to the vehicle. From the compressor you will see two wires One Red and White and One Brown. Connect the Red and White wire to the positive terminal of a 12v car battery and the Brown wire to the negative terminal. This will allow the compressor to run, check output of compressor if producing good output install has been a success and you can now proceed to refit to your vehicle.
