C3 Washer Bottle

[ABT]

Hi. I've recently got a C3 1.4hdi 70bhp 03 reg. It was my boyfriend's car for almost three years and has been a great car. At the end of last winter on one of the coldest nights, the washer bottle was partly filled and froze and has now got a crack in it so that it only holds less than half a litre of washer fluid. I've got a quote from a garage to replace the washer bottle and the bottle alone is £50 + VAT. I've tried local scrap yards and also the internet to try and source a second hand washer bottle, but to no avail. As a last thing to try before biting the bullet and getting a new bottle fitted, it's been suggested that if I can get at the bottle then I could try using silicone sealant to try and resolve my problem. I can see that the washer bottle is located behind the drivers side bumper, below the headlights, but does anyone know how I could access it? (I'm a completely un-technically minded woman, but I'm just hoping there may be a fairly simple way to reach it and fix it cheaply.) Any help would be appreciated!
