ride height sensors

hi. i have a 51 plate td5 with 120000 on the clock . i am looking to change the ride height sensors. i contacted my local independent land rover dealer who in the past have been fairly reasonable on cost .to do things my mechanic mate cant do they quoted me £270 to supply and fit both rear sensors. this seems a bit steep to me as the sensors are about £50 each and doesnt seem too be much of a job to change them. my mate looked at them and said seems an easy job to change them but .does the car need a computor to recalibrate them.. many thanks alan.

Disconnect the battery BEFORE you remove the old ones. Fit the new ones and then reconnect the battery. All should be fine.

thanks meego . ill give it a try. alan
