Even the SA was not aware where these flaps / rear vents are. He had to talk to his foreman. It seems that there are 2 options to get there: either remove the rear bumper or remove the wheel arch liners. Not sure what they did. I can go and ask if you insist

I don't think that it's a design issue. Otherwise there would be thousands of people complaining. It's probably a manufacturing issue and/or the quality of the first rear vent was not closely looked at. My car was produced during March 2009, so the very first batch.
Looking at your pictures, holy cow, you better fix this ASAP at your BMW dealership and ask an indie shop to give a closer look at the underbody rust, maybe apply a coater such as Rust Oleum.
Good luck. Peace. |
Tx for your update and info. Sigh, I have no idea where those vents are located. I guess I'll just keep doing the cloth thing unless I feel like tackling this project, it's a pita esp when techs couldn't find out easily where the leak comes from.
I do disagree and would say it's a design defect....the waterway leads to the rear lights, and then who knows where it's channeled? It's just a stupid design, and relying upon some plastic? flaps is just insane. I'm sure the Japanese are smarter than that and don't have this prb, but I thought that Germans were smart too. One would think that they would be esp careful since it's a roadster and all those electronics are back there including the roof pump, lights, various wiring, etc, but they just 'winged it' it seems. I now suspect that's probably why my right rear light died as LED is supposed to last a long time.
EDIT: I imagine what they designed is akin to having some layers of sheet metal separating Mike Tyson from the guy he wants to kill. Sure, it'll hold him for a bit but *eventually* those sheet metal WILL fail and that guy will be dead LOL. Vs look at a Miata trunk, for example, it's basically a tub and the metal surrounding is molded so that water will NEVER have a hint of going in there and will just slide off the rear of the car harmlessly. Simple, effective. I have NO idea what BMW was doing, trying to be cute and I see some stupid trim in the trunk and haven't the foggiest clue why it's there because I dunno why water is being guided there in the first place. Argh.....

Tx, that's good to know. I hate going to the mechanic for non-regular stuff.
