Disco 4 (LR4) Uneven Suspension Height

Hello All,

I am new to this forum and new to Landrovers. We bought our first LR which is a D4 2010 3ltr. So far it has been great. Recently it started giving intermittent suspension error. 3 problems I can see now -
1. When I press the increase height button it automatically goes to extended height mode. No error code.
2. Getting intermittent suspension error, upon diagnosing found error code C1A13-64. I have erased all codes and haven't got anything yet.
3. The corner heights are different. I am using a odb2 scanner to get live data. I am not on a completely flat surface thought. I have no idea what negative height means, and the height keeps changing too.

Anyone has experienced this kind of issue before ? Is this normal ? Do I need a suspension calibration ?

hi

welcome to the asylum, lol

indeed those figures are all over the place

when the suspension is calibrated ur have a zero reading then either side of that ur get a minus or a plus, all depends how the discovery is sitting , indeed best to take the readings again on a flat surface

plus did u have ur steering wheel set dead straight when u have those readings as that is also worth checking to ensure whilst the wheel is dead straight the data readings should be zero

lastly what diagnostics are u using plse , additionally ensure with the engine off to test ur battery voltage , low battery readings can cause u told errors

if it keeps going into extended mode that can either be a height sensor error , calibration required if a steering wheel angle sensor fault , please re check it on a flat area to see what the readings , including steering wheel when it’s set dead straight

hope that helps

Almost forgot , on level ground and in normal ride height , plse check the measurements from the centre of ur wheel to the bottom of ur wheel arch , should be around

front 466 mm
Rears 485 mm

hope that’s useful

As the 2 posts above, check your battery, and do so properly - search on here - make sure your alternator is up to snuff too - very complex electronics do not like varying voltages..

You can buy a proper battery tester like the Topdon BT50 for ~£50 - worth it all day long IMHO.

And, tell us which diagnostic you are using, because some of them are known to be complete liars when it comes to LR stuff

hi mate

indeed a plus 1 ref diagnostics , that Autel ap200 is becoming very popular due to it working well on the D3 , basic but with it being able to program keys is worth it with just that facility seeing some dealers are asking just under £300 for a new key when I done mine for less than £60

also as u say with regards to the alternator , seen many get thrown out when they see 14.5 Vdc + being produced from these alternators , limited to around 16vdc , plus seen some making the big mistake of not fitting genuine denso alternators , consequently then seeing there dashboard light up like a Xmas tree , lol
