Vent Discoloration/Fading

So my 1er suffered from common vent discoloration. I don't know if this is from sun fading or some other cause. I just knew I needed to fix it. Starting at it all day cheapened my ride and drove me nuts. Soo... I took a bottle of Mothers Back to Black and a foam Q-tip and went to work. I will attach a before photo below, as well as an after shot. I did 3 applications, let them sit for 5 minutes and then wiped away.








3 weeks later all of my vents still look brand new.

Thanks, I have that problem as well, I picked up some back to black for the shadowline, but didn't help, used it on my truck instead. Good to know I can use it for the vent issue.

Gtechniq Tyre and Trim, great on vents, rubber trim inside and out and has real staying power on tyres.

It's not a bad product, but as mentioned before, it tends to break down quickly. I've had good results with multiple applications of Adam's Super VRT- basically just kept applying until the plastic was permeated and no longer pulling in more product. It has lasted about 8 months now, but I'm starting to get discoloration again since the Florida heat has the AC running like mad.

Interesting. Well if this breaks down I'll have to give that a go. Thanks for the tip!

Wow, I wish I knew about this earlier. I ended up buying new vents when that happened to mine. Do you think it will fix that kind of discoloration on rubber?

I would assume so, but haven't tried it yet. It really rehydrates whatever it's applied to so I would bet it could bring the rubber back to life. If you try it on rubber hit me back and let me know how it goes!

I tried the back to black on the vents but it seems like I have a thick coat of white stuff on them and it didn't help. I also tried it on the trim on the doors where the water spots show up and it helped a little but it is still noticeable.
I think I am going to use a soft scrub sponge first and then reapply to the vents.

How many coats did you try? You might be right about a soft cleaning. I never did anything more aggressive than a rag and interior cleaner. I totally get that each situation is different, anxious to hear what ends up working for you.

I tried a few. I have no idea where the build up is coming from, but for the blacklines, I may just end up plastidipping them.

It may have something to do with the activated charcoal air filter, not sure. You can always clean them, though, with an IPA solution and cotton swabs. This is what I had to do before the plastic conditioner would really permeate the surface. Once that was done, the vents kept their color for the better part of a year.

Would this be a warranty item. Does not seem like "normal" wear to me.

Your dealer may treat it you to a goodwill replacement but don't expect it. IMO, most of the vents will start to discolor long after the factory warranty has run out and this most likely will not fall under any type of CPO warranty.

It's easy enough to fix with the right detailing product.

I'm having the same discoloration. Taking my car to BMW next week and going to see if they will cover this under warranty, if not then Back to Black it is...
