BMW X5 E53 SELF LEVELING SENSOR INACTIVE

[Lifeishard2020]

Hello,
Hope everyone's good,
If its already been covered my apologies in advance,

I've got a BMW E53 X5 2003 3.0L PETROL had the car for 6 months and have spent alot of money to get it driving all good again but I'm stuck on one thing ,

Both rear suspension leveling sensors have been replaced, air compressor pump, relay,fuses,

I never had the self leveling sensor warning light but one day my car battery dies ,
So it was left for 2 days untill I bought one which is the following power
85ah 670a
Replaced the battery left the car running for some time and the self leveling sensor warning light came back on ,
Checked all fuses and relay , air compressor working,
I also got it checked from local garage they said everything is fine but why is the warning light on ,
Isit because the new car battery is a low voltage or I need a more power one ?

Any ideas ,
Thanks

Mine came on once when the battery went down but it cleared itself when i drove the car.
The level sensors you changed where they OEM parts you used.
Seen this problem recently could have even been on here and it turned out to be the replacement part at fault.

I assume the garage used decent diagnostics and if the light is on they should have got a code. If the level sensors are set up differently that should produce a code. Try disconnecting the battery for 10 minutes again which should clear all fault codes. If the light comes back there should be a new code generated

When i do the magic reset i leave the battery off for 20 minutes.
Just have the 16 minutes to sleep in my head so give it that bit extra but that's me lol.
