2006 L322 Range Rover Electrical Issues

[urquattroGus]

We have a 2005/6 4.2 Supercharged full fat range rover.

There are a few electrical issues at the moment.

The radio crackles a lot and cuts in and out, the head unit switches on and off randomly.

It seems like a bad earth or something?

We suffered the dreaded water ingress at the rear which I traced to a worn out boot seal and the fact the tailgate was not latching all that tight.

Water was coming in on the rear nearside pillar.

Not great as it filled up the wheel well a bit and the water was running into the stack of controllers etc.

It has the Harmon Kardon system with Nav and rear screens etc.

I have pulled out some of the connectors and cleaned them, not visibly corroded, but the whole lot needs to come out.

However, are there any know issues with the head unit and or HK amplifier etc etc

The central locking also seems now not to work, key has always worked before and the red led lights up.

The battery also goes flat after 2 weeks stood.

I removed a defunct GPS tracker (flat internal tracker battery?) which I thought would solve this and stop any residual current draw, but alas it has not.

Anyway, sorry a bit of a stab in the dark but have struggled to find any good UK LR forums and wondered if there are any known issues.

Best Range Rover forum by far is this one. Very helpful

Regarding the central locking, have you checked the fuse it's in the boot, if it has blown, replace and do the key reset.

How much do you like the nav and audio system? Have you considered binning the lot and replacing with a double din and a amp for the sub?

If the amp and head unit is good, you could potentially make a bit of cash selling them.

Thanks both for the advice, have posted on that RR forum too.
