TD5 52 plate none active just rear air
Just lately every time i stop the air suspension grunts about 6 times never used to.
Yes i expect her to self level but not this much and offten
No overnight drop motor sits perfect all the time, so i dont suspect leak or she would be down in morning
plugged her in and found nothing
Any ideas please
Mark
 
It's a classic SLS system missbehaviour, quite common though not normal cos it's not supposed to relevel with ignition off only to drop a bit if load was removed from the vehicle, as long as the battery doesnt go flat over night learn to live with it or you'll need to replace the ECU with a uprated late modell after a false crank signal input was ruled out
 
SF - What was upgraded in the later ECU? Mine does this too, hadn't thought about it running down the battery. I assumed it just did it on shut down, but it could be doing it on and off all night for all I know!
