This LRO reader emailed LRO.firstname.lastname@example.org to ask Andrew Varrall about an effective way to deal with his Land Rover Discovery 2 and its height sensor problems.
Is it possible to solve ride height sensor problems on my 2004 Td5 Disco 2 without a diagnostic computer? Since having its air springs replaced, the right side of the car is about 8mm lower than the left. How can I correct this difference without a diagnostic device such as Test Book? Will the dashboard light be switched off ?

If you put the ride height sensor back to how it should be, the light should reset itself after the battery has been disconnected for about 30 minutes. Unfortunately, though, this doesn’t always work – so it’s best to put the car on a diagnostic computer to discover what has happened, because this sensor shouldn’t have been touched to change the rear air springs.
Before doing anything, look at both sensors and make sure they’re fitted in the same way. If you can, buy a vehicle-specific diagnostic machine such as the Lynx or Hawkeye; these cost about £250.
