How do you get the battery out
 

on a '01 TDI. It gets stuck under the scuttle/windscreen. Is there a knack or just have to strip it all down.

Also, I have a really bad leak from the seal around the pollen filter - I've had the carpets out twice and managed to soak up 2 inches from the rear footwell after a heavy downpour and the car was on a hill facing upwards. How can I get the seal out and is it easily replaced?

Thanks
