Help!!Washer Fluid Problems?!
Question? How much do you usually pour in the washer fluid reservoir. 
I poured almost near the top of the cap and then it started leaking out while it was parked in the garage? 
Is there a safety mechanism that triggers it to leak out under the front plastic undercarriage hole if it full? The last time I filled it up was on the drive to Benzfest and I used it all up once I got home.

hey...
Same thing happen to me when i filled up my reservoir. when i tried to fill it there was a little pressure when i opened the lid. Overall, I ended up taking it apart and replacing the rubber grommet all around which cost less than 10 bucks at the dealer. While you have the tank off check for leaks while your at it. Hope that helps man...oh by the way i just got my car all hooked up with the bi-xenons and mirror lights....I also slapped my rims back on too...it looks so much different...thanks for all the tips man.
about the check engine light, no clue about that. all i got is windshield washer low message.

Yeah my car was leaking out fluid near the bottom of the front bumper. It was the winshield fluid I had poured in. About the rubber grommets,what exactly is the part reference. I don't want to take it to the dealer, but I might have to fork out the $150 for diagnostics. Could that be why my check engine light came on after all this fluid leaked out? Maybe it came in contact with a sensor on the car giving me a "check engine"? Thanks again, oh and let me know more details if you can remember!

here is the part ref for the rubber gromet. http://www.autohausaz.com/search/pro...servoir%20Seal
if the rubber gromet doesn't fix the leak, then replace the washer tank because the hole where the rubber gromet goes in sometimes get bigger due to high temp form the exhaust manifold and new gromet will not seal the hole tight enough. very cheap and easy fix.

You might check the lines going to the headlight washers too. If pressure built up in the system as water heated from the engine, you could have gotten a leak there as well. Re-seating the lines could be all it needs.

Check the headlight sprayers if you have them. Open the little doors that cover them and make sure the sprayers themselves have not come out of their sockets cause this will cause the fluid to just run straight out behind them. Also check the hose coming off the washer bottle to go to the winshield sprayers. The hose will have some green stuff on it if it has been leaking. These are the 2 most common places for leaks on a 220.

Good points guys. I had a clogged light washer and when I turned them on one washer actually blew off so hard it put a small dent in the garage drywall. I didn't realize what happened at first and ran out of water a couple of times before I figured it out. Nasty little buggers...

Well the tech checked the headlight sprayers and there was one spray head missing out of the three. They told me they couldn't find any leaks for the windshield washers container after they refilled it with washer fluid?

I guess you know the missing sprayer is where the fluid is leaking. The sprayer head leaves an open fluid line/tube where the water leaks out. I assume you have replaced the sprayer...

Also I did not use the Headlight sprayers after refilling it and almost 90% of the fluid leaked out while I parked it overnight? 
So would it just be the Winshield wiper hoses or both? I appreciate all the help from everyone!

that is true in some cases because the extreme heat in the engine compartment somewhat melts the hole bigger and new rubber grommets will not seal the pump tightly to the tank. this happened to me on my c43 and after few rubber grommets and still leaking, i just replaced the tank and all is well ever since. my s500 has yet to leak.

I found mine in the corner of my garage and put it back on myself, and then had my dealer check it out at no charge. As I recall, they actually put a new one on for me, and I believe it was all one piece. Have you looked around to see if you can find yours? Do you recall the last time you activated the washers? That is probably where it will be. Your dealer parts department will probably have one in stock.
Good luck!

you can get the nozzle head separate which will solve the problem if its just one of the individual nozzles missing but if the whole left or right side nozzle head flew off, sometimes just replacing that part wont fix it. Sometimes the new one will just fly off too. In this case it is better to get the whole assembly. It comes with the tube that goes through the bumper and the nozzle head. However, if you replace the whole thing, you will need to unbolt it from under the bumper so you will need to take the front encapsulation panel down and look up behind the bumper.

I would just call your local dealer and ask them how much it is and if they have it in stock. If just one of the three nozzles are missing, you can probably just get away with replacing the nozzle head without the lower part. It just pops in, its really easy.
