Windshield fluid reservoir cap

rahdigga165 · 10-13-2019, 10:42 PM

So you guys think this is the issue requires me to have to fill often? I literary topped it off yesterday Saturday and checked today and i needed about 12oz of fluid to top off again in about 24hrs and 40 miles drive w/out using the windshield wiper... smh

Yes, the rubber is cracked and not doing its job of sealing the filler tube. The distillation still is in full operation and all the evidence is there in blue. You'll be surprised what the new cap will do, it will do its job.

You're correct the problem is the cap. If it ceases to be a closed system the fluid evaporates... I once had a whole gallon evaporate in a day.

Interesting, I have the same issue with the fluid evaporating quickly. Going to check this out.

On my 2015 535i, I replaced the cap for $9.58, part cost from the dealer, and evaporation stopped.

There was a thread on this. The outcome was you need to order a new cap

Ha, I just replaced mine, it looked like that too and I needed to refill every couple of weeks.

None of my local dealers had it in stock.

Thanks for the tip guys. Would never have thought to look at it, but mine too was all cracked, and my level was down.

Just ordered P/N 61667238068 from Amazon.
