Height Sensors D2

Evening Folks,

Discovery 2003

I’m having to replace my air bags and my ride height sensors. Can anyone shed some light on the part number , best place to buy these and what the actual brand is to the genuine ones

Ride height sensors are RQH100030. Genuine are £110 each so I wouldn't bother. I've had a pair of the Britpart sensors for over nearly 4 years without issue. They're a 3rd of the price. The Britpart "OEM" ones are also available for a price somewhere in the middle.

Air bags RKB101200. Contitech or Dunlop.

Do the sensors need calibrated once replaced ?

Depends, if one of the old ones failed with open circuit or if they were unplugged whithout the battery to be disconnected first then calibration is compulsory, also it's possibe to have to calibrate if they are other brand so better expect it to be necessary.

Don't know how accurate my 'calibration' was but after changing airbags I let car rise to normal height.
Turned engine off then disconnected sensor arm, not electrical connection, moved it slowly through it's operation, up and down. Refitted and all was good. While there, with ignition off I gave the connections a clean with electrical cleaner.

I used to replace with genuine LR sensors, but they don’t last any better than aftermarket ones. Jack it up so the axle is hanging then disconnect the battery before you do anything and it should be fine. LR would tell you it needs connected to their system tool, I think it’s called Test Book, to deflate the bags, but just puncture them with something sharp. It’s not a difficult job really.
