Hi from Greece..in the last month I've purchased mini couper s f56 and I'm having some trouble.. I've noticed In the back lantern some moisture. Then I changed it with a new one and the same happened again. Today I saw that there's moisture in all the lanterns. Has anyone noticed something like that?

thank's :)

Hi miniGR

By "back lantern", do you mean the insides of the red cover for the tail lights? What exactly did you change?

Not sure what you're referring to here...

I have replaced the lights with new ones and have noticed the same amounts of moisture. Today I noticed this moisture in all lights. Has anyone noticed something similar to this?

I am assuming you replaced the bulbs inside the the light housing. Not sure why you would do that, unless they were burnt out.

If I understand you correctly, there is water inside the red lens. That sounds like a missing or faulty gasket between the lens and the body of the car. That would be part 5 on the attached image from realoem.

No I didn't replace the bulbs. I had them replaced the whole break light.

Is it possible that this would happen to all the lights?

By "all the lights" do you mean the left and right brake lights? Not the front lights? And specifically which part in the diagram did you replace?

Why did you replace them? And how much water are you finding? It is a little bit (like condensation), or is it sloshing around in there?

Lots of questions, I'm sorry, but I'm trying to figure out what's going on here :)

It seems like part 5 is the gasket, which is fine because I was present when they replaced it.
could the weather, cause here we have rain and cold, be responsible for this?

They didn't just replace one part. They replaced the whole left break light.

Ah yes. A picture is worth a thousand words.

Looks like condensation on the front light. So let me see if I have this straight:

1) You had both rear light assemblies replaced

2) You also had both front light assemblies replaced

3) All of the assemblies which were replaced now show condensation inside.

I'm going to guess that it was probably warmer when you had the lights replaced. Warm air holds more moisture than cold air, and the air trapped inside the assemblies is relatively moist. Now that it's cold, the moisture is condensing on the glass.

Or, if the lights were replaced during a rainstorm (literally the car was being rained on while the work was going on) , that could cause the problem as well.

What you need to do is warm up the insides of the assemblies and circulate some warm air inside. That will evaporate the moisture and clear up the condensation. What I would do is borrow a hair dryer or heat gun. Remove the bulbs from the rear lights, and blow hot air inside (careful not to melt anything!) for about 10 or 15 minutes on each light. That should evaporate the moisture and clear up the fogging.

For the front, it looks a little more involved. I can't tell if it would be possible for you to use a heat gun, but the good news is the lights themselves might provide enough heat to eventually clear out the moisture. One thing you can try is wait for a dry time and drive for a while with the headlights on. Then find a mountain and drive up it (that will draw the air out of the housing as you gain altitude).

For what it's worth, that's what I think. One of the experts here might want to chime in also.

In any case once it warms up you should see the condensation disappear.

I would say it is quite likely to be "weather" related, or at least temperature differentials causing condensation inside the light, or lamp, housings.

I had a Toyota that had damp inside the rear lamps, but discovered so did a lot of other people depending on the weather conditions, so I just forgot about it!

It didn't cause any problems and went away when the weather improved.

If Mini are keen to investigate further, then let them, if it concerns you.

Edit: Sorry, I was writing my post when Uke replied and we seem to have said much the same things!

And the International Global MINI Troubleshooting Team chalks up another victory! This forum is great.

Yes, please let us know how it turns out. We love success stories. And we love learning.

I had a 1980 Camaro that regularly tried to fill its tail light lenses with condensation water. It was like two little aquariums back there. I was tempted to just go with it and keep sea monkeys in there. This is one of many reasons why the Camaro was deservedly discontinued. They should have saved the Camaro name for some kind of communist manufactured econo-nightmare that looks like one of your grandmother's shoes.

I had exactly the same condensation in my LED headlights the other day. It was pretty cold out (2 degrees C). It has since cleared. It may just be in extremes of temperature, as I haven't noticed this before. I don't think that the LED lamps will create enough heat to dissipate the moisture, but as long as it isn't interfering with the operation of the headlights I wouldn't worry about it.

Ok thank you so much guys...!!!
I had the same problem with one of my side lights (the one just in front of the door). The dealer replaced it, (the car was only 2 days old).

I had the same problems with my R56 'S', it was condensation in the fog lamps, apparently that was a common problem - lots of owners reported it and I never successfully got mine resolved in 3 years of ownership. Not a very positive post I'm afraid.

I'm sure it's a differential between moisture in and out of the lamp and the temperature. I occasionally see it in my front leds but it seems to vanish and reappear occasionally. Nothing to worry about I don't think.

I'll second Jeremy's comments - if it's just a light fogging which dissipates after the car's warmed up then I don't see this as an issue. However, if you notice liquid building up in there over time which doesn't drain then I would be tempted to go back to the dealer.

I had this happen on the mirror indicators of my SLK and after a year when I noticed the condition getting worse they did replace them under warranty.
