Thread: Suspension + DSC + handbrake + brake warning lights

Coming back to WA from South Austarlia, our 07 2.7td would be going along nicely then suddenly drop in to neutral and the car would lower, we would also have limited engine power. the messages we got on the dash were HCD command Failed and various messages about the car being at different heights once we had the compressor needs to cool before the car will resume normal height.
We had stopped the car several time and shut it all off and restarted it, disconnected the battery for a few minutes and the last one getting everbody out and locking and unlocking it several times to see if that would solve the problem. which it did for short periods.
We seemed to be able to drive in 3rd at about 80ks and it got us back to Penong

This was just before Nundroo crossing the Nullarbor with temps in the low 40s with 4 kids in the car, we decided to turn back and head to the nearest dealer in Port Lincoln 500ks away.
Once we left Penong for PL the car drove with out a problem all the way, the dealer ran his computer on it the following day and could see all the error messages but could not specify an exact problem, maybe some canbus issues. They loaded all the latest software updates and sent us on our way.
the car was fine for the next 1500ks until just near Balladonia it all started again. gggrrrr
We have managed to limp home but the problem is still occurring occasionally, our closest dealer is about 6.5hrs away so maybe a slow drive there this week.
The guy in Port Lincoln did say the battery was on the way out but it is only about 12 months old.
any ideas please?????

Low battery voltage is a well-known cause of various faults.
