Looking for tips on how to do this myself at home, or the cheapest tool that I need buy to let me do this myself at home?

I repaired (successfully I think ) a leak in the rear left airbag connector, and now everything works fine, except that that corner of the car sits about 40 mm lower than the other three corners. All 4 corners go up and down fine, it’s just that whichever ride high is selected, that one corner now settles about 40mm lower than the other 3 corners settle at. No error messages.

Looks like I need to be able to adjust or calibrate a setting somewhere. Any recommendations on the most efficient, cheapest way to me to do this?

Cheers!

Thanks, Will. Looks like that one sold and new ones are $6-700 ish. Do you know if there is anything less expensive out there that can make the necessary adjustments?

there are other diag kits but i don't know which would be able to calibrate the height but I'm sure there is some one on here can point you in the right direction  2008 3.6 tdv8 range rover Vogue Stornoway grey - Parchment Leather
