Hi,

Got a 53 Plate Discovery 2 TD5. The left side of car sits lower than right.

Got a snap on ultra which shows the right height is 227mm and the left is 213mm. There is no fault codes at all or any warning lights.

What would you suggest doing from here????

Thanks
 
14 mm difference doesn't sound like it's earth shattering, in fact there are very few Discos where there's absolutely no difference.
If it's really worrying you, then the first thing to do is check the bushes on the ends of the ride height sensors. Disconnect the battery before you do anything like disconnecting or removing the sensor units.
If the difference remains the same over time, then it would look like there are no leaks in the airbags.
To actually alter the ride height settings you will need a compatible diagnostic code reader.

could an air leak cause the issue ??

hopefully someone else with more experiance than me will be able to more accurately answer ur question

sorry not much help , only thing i can think of
 
Mine was like that I got really OCD about it especially on garage forecourts - I just went and got mine recalibrated by a LR specialist
 
What are the actual measurements?

normal height is 473mm +-15mm on the read from ctr wheel to the wheelarch.

It is not uncommon that as @brian47 says the rubber in the fixing points on the height sensors fail. Causing a lopsidedness.

But do heed his warning about disconnecting the battery before diconnecting anything.

Cheers
 
Mine was set that way by the mechanic and I was told that it is set this way so as it sits level when the driver get in. It is considered 'normal' to have just the one person in the vehicle and that is the driver!! As I don't see it when I'm in it I just assume it is then level:). I have never had any problems so I just believe this is true.:D

Funny,, unfortunately the workshop manual does not specify a different height for driver / passenger side.

Also if this was the case why would all cars not have the same thing happening?

I don't think that method should apply, it is, after all a Self Levelling Suspension System, with the emphasis on the self levelling.
 
Don't ask me!!!!!!! I just believe what I'm told and as long as my D2 keeps going I'm happy:) It's done 16+ years now and just about 240,000 miles so I'll stick with my faith in my mechanic's reasoning.:D:D:D:D I'm a firm believer in 'if its not broke don't fix it'.
 
Still original engine, original gear box etc. but a new Richards chassis. I whisper nice words of encouragement to it every morning just to let it know I really appreciate it. :D:D:D Yes, I am mad but it does seem to have worked so far and it knows that I would never verbally abuse it!

Certainly not uncommon!

My new ones have a metal sleeve so should be plenty tough vs. the old ones

We don't know yet, I have asked whether the difference does stay the same over time which would indicate that an air leak is probably not responsible this time.

Very basically there are four major components in the air suspension system: the airbag springs, the ride height sensors, the air compressor and the self levelling suspension ECU.
The ride height sensors will detect the height of the chassis above the rear axle and sends that value to the ECU (part of the SLABS ECU). The ECU compares the values from the sensors with the initial values set in the ECU at the last calibration set up and will then signal the compressor to either inflate or deflate the airbag springs as appropriate in order to bring the values to the ECU from the ride height sensors back into the proper range of the initial setting. The normal operation is completely automatic.
There are obviously other things to consider in a fully operational system, but that is very simply how it works.
