Tesla X - Kompressorin ja ilmansuodattimen asennus

By Odd Arild Johnsen 

Below is a picture series made by Odd Arne Johnsen and which teslasuspension.com has been given permission to publish. The main difference to the procedure in the Tesla Service Manual is that a new air filter is installed and the intake is moved further into the «frunk». This is done to avoid condensation runoff and moisture ingress into the compressor, which has been a problem on the original setup.

New air filter can be purchased directly from Tesla (part number 1027931-00-B, EUR 15). Replacing it is necessary for the warranty on our compressors to be valid. The same applies to the relay, if you do not have an eFuse (part number 1080796-00-A, EUR 20). We also recommend to install a new valve block, if you are unsure whether there is moisture/corrosion in it.

Always start the work by setting the air suspension in service/jack mode and releasing the air via the hoses on the compressor. If you have an MCU2, you can alternatively enter service mode via a code on the screen and deflate the air suspension system. Also remove the «frunk», if you intend to modify the hose inlet on the air filter, something we recommend to do (see pictures 12-15).

The installation procedure is accordingly the reverse of the dismantling steps just with new modifications of the air filter.

Then, install the «frunk». This is to check that its not putting any pressure on the new hoses.

Install the arch liner and put on the wheels.

Close the hood, turn on the car or deactivate the air suspension's service/jack mode.

The compressor starts and the car's air suspension system begins to inflate.

It is important not to let the compressor run for too long. Under no circumstances should it run for longer than 30 seconds. If it does, go to «security» and scroll all the way down, press «power off» or put the air suspension in service/jack mode again (just opening the door can also work). Wait at least 5 minutes before starting again. This will prevent the compressor rotor from going hot.

If you get an error message that the air suspension will not lift, it may be that the electronics measure too low pressure in the tank and suspect a leak. Then you can - when you turn on the car - try to put it in drive, but hold the brake. The compressor will then run for more than 10 seconds before it cuts off on its own due to the pressure in the tank.

Once you have inflated the car, open the hood and listen for leaks. You should not hear any hissing. Remember to «power off» the car before you do this, so you don't hear any other noises floating around there. If everything is tight, and there are no leaks or noises, the installation is probably well performed and the job is done. Finish with a test drive.
