Anybody know how to stop water leaking into the spare tyre well..
Drained it yesterday. Also removed battery and cleaned out the drain that located under the battery which was clogged with dirt.!
Just wondering would this effect the boot/trunk also

It's possible your sunroof drains are clogged if you have a sunroof. Possible hatch or trunk seal depending on your model

Or rear washer line if you have a rear washer.
It would help if you stated the type of car.
