Since its pretty warm in the RVA I have noticed little trails of water spots down my hood starting from the nozzles. I passed it off as some dew possibly or when my family moved the car in the morning they used the washers.

Well I saw it again this morning before leaving for work. This time I know there was no dew as the car still has a light dusting of pollen and it was not moved this morning. I did some searching and noticed that previous R56 models had this and some posts about check valves.

Anyone seen this on a 2011 yet. Luckily the RainX fluid I use just rubs right off and no stains but its really annoying to spend hours on Sunday cleaning and such then see little trials of spots down the hood...

 

+1 on annoying.

I see it as well on my '11 S Clubman. It did NOT happen on my '09 HT.

Does yours weep only after using your washers, or always / whenever? Out of curiosity, do you have headlight nozzles?

I seem to notice it more after using the washers. Intend to do a little more troubleshooting on this (e.g., spraying when stationary and seeing what happens to bonnet; cleaning bonnet and not spraying to see if it weeps, etc.).

In any event, the next time I'm in there, I plan to let the dealership know it's unsat and I want it fixed.

 

Mine is the same, yea it sucks mine only does it when I use mine to clear a bug suicide. VERY ANNOYING!!!!

 

I'm thinking there's some fluid that remains in the line just upstream of the nozzles. Heat, and/or the vacuum of air passing over it (bernoulli effect) pushes/draws the fluid out onto our otherwise pristine bonnets..

Going to mess around this weekend troubleshooting...

 

I have not used mine in the last week but once when it was raining to get he bugs off. It seems the every time I get done driving they weep. It really annoying.

I have tried to leave the cap off the bottle but thats not helping anymore the hotter it gets.

 

I'll keep an eye out on what you find out I sooooo want this fixed.

 

Haven't tried to troubleshoot myself yet, but it does look like a heat / expansion issue that's been going on for years in mainly the S models (which lends credence to the heat concept):

Yep I read that thread also. It does seem that the 2011 has a check valve in between the two nozzles but its obviously not doing its job.

 

I get also on the S and not on non S. Heat and or speed.

 

Mines doing it even more now, so its going in again.

 

The checkvalve concept makes sense to me; however the valves need to be positioned closer (i.e. just upstream) of the spray nozzles in order to be effective, IMO. Otherwise - even if the checkvalve serves its intended purpose, there is still fluid in the line between the valve and nozzle that can ultimately weep.

Let us know what the dealer does / says please.

 

Will do its going in on Wednesday.

 

Dropped the car off this morning for this and some other minor issues.

We shall see how this is handled.

 

UPDATE - Got the car back from the dealer last week. They installed two more check valves right behind the nozzles. So the 2011's still have this issue.

 

my 2007 has been doing this for some time. I will have to see if they have check valves in the older models.

 

Dealer did the same thing for me on my 2010 a year ago. While it lessened the issue, it didn't eliminate it.

 

Did it work? I think right behind the nozzles is the best location.

Would you please post a photo of what they look like (are they the same ones in the photos in other posts / threads)?

Thanks.

 

Well in the 5 or so days I have had it back its not done it yet.

 

Keep an eye on this. Happened so badly on my 09 that it ate through the clear coat to the point my bonnet had to be repainted after only 4 months c

 

I noticed on my Clubman as well. Looks like I'll have to bring it in.

 

Does it on my JCW. It's already damaged the stripes to the point that the water spots/streaks can't be polished out.

 

Wow if I have paint damage they are so going to get it....

 

Just got it in Jan. Does it on my 09 JCW! Stripes got spots! Going into the shop Wed.

 

Here is a pic of the fix. You can see the center valve that was there from the factory and the new ones just behind the nozzles.

 

Any update if this has resolved the issue? My 2011 MCS does this and my Midnight Black Bonner isnt liking it too much!
