Clutch/brake fluid leak under battery - 04 1.9TDi

[David Carter]

Hi, new to this forum and hoping someone can assist...
I have spotted a fluid leak which appears to be coming from somewhere underneath the battery. There is a fine layer of fluid covering components directly underneath the battery box. Can somebody pinpoint the most likely cause?
Thanks in advance for any help

Yours has the external slave cylinder so it could be the nipple or hose connection leaking or the feed hose/pipe assembly which pre mid 2005 was a known weakness on all PQ35 platform cars and has been revised at least four times, I get the current number as being 1K2 721 465 BJ which is £98.65 genuine and as far as I can tell is genuine only.
