I know a few of you have experienced this, sometimes before AND after the leaky tank was replaced by the dealer... This is a fairly new TSB, # LS501-022.

Washer Reservoir Leak
AFFECTED VEHICLE RANGE:
Range Rover Sport (LS) VIN: 6A900129 to 6A975520

CONDITION SUMMARY:
WASHER RESERVOIR LEAK
Situation: A customer may report a concern of a fluid leak from the front of the vehicle. The fluid leak may be suspected to be a coolant leak from the radiator. A close inspection could reveal that the windshield washer reservoir is the source of the fluid leak. A manufacturing process problem could have resulted in a weak seam at the base of the washer reservoir. The weak seam may have failed. Action: Should a customer express a concern of a fluid leak described above, refer to the Repair Procedure detailed in this bulletin to inspect the washer reservoir and rectify the concern as necessary.
PARTS:
CAUTION: A replacement reservoir must meet the inspection criteria detailed in this bulletin. If a reservoir does not meet the inspection criteria, Retailers are requested to submit a "ZRTN020" credit request. Once a confirmed response to the credit request is received the
part may be scrapped on site. This technical bulletin number should be referenced in the credit request.

DMB500040.............Reservoir - windshield washer, w/ headlamp power wash Qty 1
DMB500030.............Reservoir - windshield washer, less headlamp wash/wipe Qty 1

CAUTION: A replacement washer reservoir must have either a yellow paint mark on the side of the reservoir, identifying the reservoir as a quality-controlled assembly OR a date of manufacture later than '25/07/06' (25th July 2006).

I have a July 2006 build HSE in that VIN range and it took about five weeks for the tank to start leaking. Been replaced, so far so good.

mine was leaking extensively - the entire content in 2 hours was gone. Replaced by the dealer in 1 hour (@ ~ 6k miles)

Update, 3 1/2 hours later.

After removing the bumper, the cause of the leak was not the aforementioned defect in the reservoir seam. Sometime in the past with the PO, the headlight washer portion of the tubing was disconnected, and the fitting coming out of that pump was covered with a latex glove and some masking tape. I removed this crap, covered the end of the fitting with a blue silicone vacuum cap and tested for a water leak. Problem is solved for now. No leaking from the tank itself.

Now I need to figure out what to do with the brand new reservoir purchased from Atlantic British.
