Water under battery.

[Lammie_J]

I'm having a problem with water ingress under the battery.

Is this a common issue? Has anyone got a solution?

The boot rubber all appear to be good.

Touch wood I've never had this problem. Hope you get it sorted.

Had water in the boot on a E36 m3 when touring France. Dried it out & it never retiurned. Strange, but I was not comaining.
