Replacing Air spring/air strut/pneumatic spring F07 550i Gran Turismo

This repair is pretty easy.

1. Jack up and securely place jack stands underneath. Block front wheels.

2. Remove rear tire.

3. Grab the air spring and twist counter clockwise approximately one half turn.

4. Pull air spring out. **Make sure all air is out of air system. My spring bag had a hole in it.**

5. Take a 10m wrench and unscrew fitting from the top of air spring that has the air line that goes into the top of the spring/bag.

6. There will be a small brass ring on the end of the air line.

7. Remove the fitting in the top of the new air spring. Take the new air spring and insert the
air line into the top of the air spring. Push the air line in to a stop. Screw the fitting in. Make sure the two piece fitting is unscrewed to allow for maximum thread area exposed. Then tighten the fitting into the air spring.

8. Put the air spring back in the cradle at top and bottom mount area and turn one half turn clockwise back into position.

9. Replace tire.

10. Put car down on the ground.

11. Restart and the bag will air up within 30-60 seconds.
