Range Rover sport L320 2010 warning lights blank cluster

[Tan125]

Hi all
I have a Range rover sport 3.6v8 2010. A couple of weeks ago whilst driving various warning appeared
Lack of performance
No forward alert
HDC fault
Red and yellow triangle
Car went into limp mode. If you restart errors disappear and she runs fine.
However yesterday jumped in she started ok then I noticed no rev counter or Speedo works, no radio, no blower , no indicators showing on the dash board.
Any ideas before I start pulling things apart
Thanks all Tan

No expert but maybe the first thing to try is checking the battery is all fully charged and sufficient for the vehicle.

Read on the forums that loads of errors can appear with L322/L320 if the battery is weak.

Hi there
Thanks for the reply
I checked the battery on load and it looks good
Pushing out 14.7 v with headlights and heated seats on.

Currently trying to find Range Rover sport 2010 wiring diagrams as I think it could be a ground point issue as the feed to the blower has gone
Cheers Tan

On the old D3, a load of weird issues would appear if the brake light switch was faulty or a brake light bulb failed, so might be worth looking at that as well.

As you say, the earth trap might be worth looking at as well.
