Hi all
Was reading through a Land Rover buying guide today which came free in Land Rover Owner Magazine & was curious about some buying advice on the L322.
I currently own a 2004 L322 Vogue, 3.0 TD6.
It was stating what to look for and top of the list was the usual water ingress on the rear near side. It states the following "Water plays havoc with the electrics and can catch in the rear wells in the boot-fogged up rear light lenses indicate water ingress and if water is present it will affect the audio & sat nav"
Now this I agree with as we all know this is a common fault.
What has worried me is the fogging of the rear lenses, I believed this was normal on the L322 models. I have no signs of water ingress on mine and I regularly check the boot areas. I have had fogging of the rear lenses after i've washed the vehicle, this seems to clear quiet quickly. I'm sure I read a post that it was common and normal for rear lenses fogging?

Not just fogging, the rear lights fill with water:rolleyes: Holes drilled at the bottom let the water out.:)

Keith,
I take it the lenses are pre factory drilled for drainage?
Call me thick LOL:eek:
Like I stated I do get a little misting.
Was thinking you know I could add a gold fish as an after market extra:dance:

TECHNICAL INFORMATION
Water Ingress into Tail Lamps
No: 86/06/05/NAS
FGN 417-01
Ref:
Issue: 1
Date: 21 July 2005
© Land Rover 2005 Page 1

AFFECTED VEHICLE RANGE:
New Range Rover (LM) 3A101020 to 5A186201

SITUATION:
CONDENSATION OR WATER INGRESS INTO TAIL LAMPS
A customer may report a concern of misting evident on the inside of the tail lamp lens. The misting is
generally caused by natural condensation and can be expected under certain atmospheric conditions.
However, water can also enter the lamp via the breather tube under extreme conditions.

RESOLUTION:
INSPECT FOR WATER INGRESS AND CORRECT IF INDICATED
Upon customer complaint of tail lamp water ingress refer to the Service Procedure detailed in this
bulletin.

PARTS INFORMATION:
XFB500360..............Lamp assembly RH rear NAS Qty 1
XFB500370..............Lamp assembly LH rear NAS Qty 1

DDW WARRANTY CLAIMS:
NOTE: Repair procedures are under constant review, and therefore times are subject to
change; those quoted here must be taken as guidance only. Always refer to DDW to obtain the
latest repair time.
DDW requires the use of causal part numbers. Labor only claims must show the causal part number
with a quantity of zero.

REPAIR PROCEDURE
INSPECT FOR CONDENSATION
NOTE: Normal condensation is a natural process.
Range Rover tail lamps are vented to alleviate
changes in pressure through a breather vent.
• Atmospheric air contains water vapor referred to as
humidity. When this air enters the tail lamp under
any circumstance, there is a possibility that
condensation can occur if the temperature is cold
enough.
• When normal condensation occurs, a thin film of
mist can form on the inside surface of the plastic
lens. The thin mist will clear and exit through the
vents during normal lamp operation.
1. If condensation is reported, determine if it dissipates
during a thirty minute period of normal tail lamp operation
as the lamp heats up.
2. If considerable water droplets remain at unacceptable
levels on the inside of the lamp lens at the end of 30
minutes (Figures 1-4), replace the lamp with the latest
configuration.
3. If there is evidence of standing water within the lamp unit,
replace the lamp with the latest configuration.
NOTE: GTR lookup sequence is as follows:
GTR Home > NAS > Service Information/ LM New
Range Rover/2005 > Workshop Manuals > Range
Rover Workshop Manual - Service Procedures >
Bookmark "86-2 LIGHTING" > Link "86.40.70 Lamp
assembly - tail"
4. If the complaint of unacceptable condensation/water
contamination is confirmed, refer to GTR section 86.40.70
and replace both tail lamps.

Or you can drill a hole in the bottom:rolleyes:
 
The factory lights have breather vents

They get crushed closed and don't work

Drilling a couple of small 2mm holes in the bottom of the lights can work

Cheers Hippo,
Still considering adding a goldfish in the lens as an aftermarket extra:dance:
 
The original Units did mist up as mentioned and this is apparently totally separate to the 'Water Ingress' issue....

Drill hole is a cure to this.

That being said, if you do get misting up, a check of the corners of the boot wouldn't go a miss in any case.

I take it they go straight in Hippo? any mods req?

Nope, sadly not mate.

Modifications are needed to the fixings to the body and not to mention you need some electrical knowledge as resistors and relays are required to get everything working properly. Oh and diagnostics to reprogram the LCM ecu !

Worth it though ;)
