Cause of Battery Drain - Interior Lights/Washer Wiper System

[Contigo]

Hi All

Following on from my battery problems, I took the car to my local specialist after replacing the battery with a lovely Bosch Silver S5 and in sleep mode the car was drawing about 0.6A so way over the recommended 40mA. The source of the drain after removing various fuses was Fuse 27 (Washer System, Trunk Lighting,Glove Box Light).

Now does anyone have any idea where to start finding what is causing this presumable short circuit? I have been thinking about disconnecting the screenwash pump and checking for a clean earth.

Also there is a LCM in footwell which may also need checking for signs of water damage.

Thanks in Advance for the suggestions and I finally feel like I am getting somewhere. It's either find the root cause or drive around with no interior lights or wash wipers!!!!!! HELP!
