This is a hard one to title but just wondering if there are any solutions to getting rid of the constant rain or snow(depends on weather conditions) that collects on the back of my 2005 S while driving. I have a spoiler but I think it might add to the problem. While driving in wet or snow conditions the rear window is always covered with rain or snow, quite annoying..

just wondering, I think this is a real design flaw of the car as not only the rear window but also the lights get covered in snow when driving..

 

I have an 04 R53, and I have the same problem. I'm just glad I didn't remove my rear windshield wiper, or else I wouldn't be able to see a thing in the back.

 

There is no solution. It is physics at work, there is a negative pressure zone behind the car and it sucks bits of junk back onto the car, turbulent air and such.

You'll have to continuously run the rear wiper with any kind of moisture on the ground.

I always wonder how anyone can go and delete the rear wiper, this is simply unfathomable if you actually drive your car.

My car can be spotless on 3 sides yet one can't tell what color the paint is on the back.

 

Yea, it is impossible to not have that issue. I even considered getting mudflaps on my 08 MCS, but after reading reviews on here about how useless they are I said forget about it.

 

What'a isa behind me, is notta my concerna..........

 

 

Lateral acceleration is your friend. This is a hatchback feature. Not much to be done about it.

 

That's why they fitted a rear wiper and gave it an intermittent setting. I use mine all the time whenever the road is wet.

MINIs are notorious for having a "dirty boot". The one thing I've done is to put RainX on the rear window and tail lights on a regular basis.

Having driven a cube van, one can get quite used to driving with a rear view from the side mirrors only!

Just kidding - and not only do I constantly use the rear wiper, I also use the washer almost as much if not more than I do for the windshield. Since I have not been able to find a rear washer bottle and don't seem to run out, I am assuming it gets its liquid from the front windshield washer reservoir. Is that correct?

 

Side mirrors FTW!

 

It looks like a learn to live with it item, but will try the rainX approach. I have a rear wiper and do use it but i hate the sound of grit on the wiper. I live in eastern Canada and we use salt and sand on the roads in winter so back of car is always covered, turn on wiper and all you hear is grit on glass.. not nice

 

Yes, that is correct. The front reservoir supplies both systems.

 

there is also the JSArt wing tip, which they claim will change the air flow. I highly doubt it would change the charachteristics of snow, but maybe summer dust.

Looks great at least

 

You could look into the rear wing kicker from Group 4 Autosport. Reportedly reduces the grime on the rear area.

I'm curious about this as well. I'm less than thrilled that spending hours detailing a car can be foiled in minutes by how dirty the rear boot gets.

 

FWIW,

I did bite the $$ bullet & installed OEM rear mud flaps; (see my gallery), and they actually did reduce the rear boot grime by about 65%. That said, it still gets obnoxiously dirty when it is precipitating in winter, ; summer rain = not so bad.

 

Where can one source rear mud-flaps for an MCS?

I've only seen them for the base models.

 

The bumpers are different and thus there are none for MCS. But I highly suspect that a resourceful individual can get them to work. I have never seen a pair so I do not know if fitment is just a matter of some light trimming or not.

 

I wish I could remember where, but I saw a picture of an S with a set of flaps fitted to it yesterday.

Definitely going on my to-do list. Really can't be too tough to mess with a bit of plastic.

 

Yep. My car is currently DS on three sides and a very disgusting off-white in the back.

Mudflaps won't do a whole lot for this issue. You're going to have to get a car without a hatchback if you want to remedy that issue. Due to the design of the car, it distorts the air behind the car and pulls up a lot of gunk. Pardon my lack of scientific terms. Maybe a rear diffuser?

 

yep one of bad things about a hatch is all the dirt and moisture that collects on the back window. You could try using rainx to help the moisture run off? I havent tried that but it might work

 

Paraphrasing?

 

Count your blessings.
Having a Cabrio, I have to keep a spray bottle with winter washer fluid in the boot, along with a squeegie.
I am the rear wiper.
But he's worth it
