Hi my 2011 l322 tdv8 4.4 is having a few electrical problems, some times it’s fine and then it’s not, the other day air bag light was on when I stop and restart the car it’s fine again, this also happens the same too, heated screens, air suspension, radio, and tonight suspension fault do not drive above 30mph after 30 seconds car was fine with no faults on dash.
 
Hmm, I would get the battery checked for capacity as these machines are power dependent.
Even if it reads 12.6v it still could be low on capacity. A battery at 70% is on its way out and can cause all kinds of issues. A failing alternator can also cause similar issues which could also lead to battery and alternator failure.

+1 ^^^^^ Also check for damp carpets and underlay and for water ingress in the rear N/S quarter.
 
Tonight I’ve had front left suspension dropping, I’ve put computer on and it seems the height sensor is faulty, so hopefully I can get one tomorrow, the carpets are dry I’ve looked in the back by Ecu all seems ok, does anyone no what earth wires in the drives side arch are for, cheers Phil

Just keep an eye on the other gremlins. It may still be battery. I have learned by experience that one fault can be hidden by another :)
 
Fit new height sensor today, that’s sorted the 30 mph warning, after 40 min drive suspension fault came up in amber, c1130 on scanner, think soapy water out tomorrow, but looks like both front bags have gone down over a couple of hours
 
a new 110 amp battery can be purchased for around £140 with a five year guarantee if you hunt around, worth buying so you can start with a nice fresh power source which can help rule out other issues

An MF31-1000 can be purchased from Battery Megastore for about £100 delivered.
Anny new battery needs to be put on charge for 24 hours before fitting.
