Ugh... I'm taking my car in for a service this week (bass cutting off randomly from the sound and alignment that they have to redo as they can't seem to get it right the first time - ever), so I figured I'd remove my Bimmertech amp to make sure they didn't blame the bass issue on this.
Well, as I was removing the power cable, I noticed a solid 1/8'' of an inch of standing water in the bottom of the trunk (in «front» of the battery, if you will). My driveway is slightly uphill, so there is probably more behind it.
Mind you, we were out on vacation for two weeks and it rained a lot, but still, this is NOT normal.
I managed to soak it all up with paper towels and left part of the trunk trim unclipped to allow easy access to recheck it this week before my appointment.
Judging from the dampness of the inner insulating material, the leak came from the driver side rear, probably near the taillight.
It *seems* like the rubber moulding/weatherstripping was not properly squeezed onto the sheet metal, so I slammed it back on as best I could and applied some gummipflege-type stuff on the moulding/weatherstripping.
I then sprayed some water and put my hand back where I thought the leak was, but so far it's hard to tell, as everything is damp anyway.
I really like that car from a driving standpoint, but reliability-wise, it's lightyears away from my GLK. Hell, even my 2014 Fiat 500 is rock solid compared to it...
