The infamous B-Max boot leak
The B-max is prone to water entry into the boot. Mine had been absolutely fine until I had a bumper repair and then water appeared in the spare wheel well and saturated the boot underfloor carpet/soundproofing. It seems likely the bumper repair has affected something but the bumper itself is now potentially fragile and I doubt if I can remove it to check anything without damaging the paint. I did however strip out the boot contents, floor, and side trims to investigate. Reports online suggest that some holes in the bodywork- usually covered in waterproof tape, can permit water entry. Checking my boot I found the tapes on the left side to be intact and dry- those on the right were detaching. They oozed moisture and leaked water into the boot when it rained. I removed the leaking tapes. This revealed 3 holes, the middle one of which opened to show a foam sponge which was itself wet. Water was entering the boot from the rounded hole towards the bottom. I sealed these holes with Tiger bond...
