2003 Range Rover HSE fault

My partner has had this car for 2 weeks - he isnt good with IT, so I get to post for him!

There seems to be a battery drain as it goes flat and car will not start if the car hasn’t been on a good 30-minute run i.e. if 2 consecutive days short 5 minutes trips with stopping and starting the third day the car will not start.
Also, and may be connected some warning lights have appeared on the instrument panel and they all come on together not always but regularly being the 3 amber lights which are the DSC/ABS/EBA.
Also, below in the pixel’s information the messages Air Susp. Inactive and HDC. Inactive alternate and are on at the same time as the amber warning lights.
Also the back brake light stays on when the warning lights are on.
I would be very grateful If there are any views or suggested solutions.

Sounds like you already know you have electrical issues and parasitic drain occurring.
Take it to a decent auto-electrician for diagnosis maybe?
Or, go hunting for the drain yourselves.

Hello and welcome

First thing is to make sure you battery is 100% a ok as these motors will throw up faults left right and center if the volts drop.
as mentioned post over in the range rover section.

Hello and ditto, I posted some time ago that my RR had exactly the same issue. Follow the advice and get the battery up to full charge or replace if required. If you can check the earth straps around the engine to chassis as mine were very corroded. Check when you switch off and lock that the management systems fully shut down as they restart every time you unlock the car and run on for 20 minutes on locking. If you don’t drive the car long enough after, you don’t replace the drain. If the codes don’t clear with a fully charged battery as mine, I had to disconnect the battery every night and re-connect next day for a week (following the correct disconnecting procedure) before everything returned to normal. A flat battery will cause mayhem as stated and no amount of code reading will avoid it. Battery first the come back if there’s still an issue before sending it to the garage.
Cheers Tricky.
