C63 Heated Screen Washer System

[Benjy]

Guys,

Quick question what is the Heated Screen Washer System?

Thanks

Its a heating element driven off the coolant of the engine through the bottom of the screenwash bottle to heat it up.

and it costs extra on the C class and standard on the E. Have you got one>? If you have and spray the steam rises off the windscreen when the hot liquid hits it.

Ahhhhhhhhhhhhh.......Thank you ever so much for the info.....Yes I had it fitted and thought it was a heated windscreen. Doh!

I have it too but not sure exactly what is included - I believe the washer jets don't freeze so you can spray the windscreen and the water bottle is heated (don't know how). Would like to know details myself.

The jets are already heated as standard on the C class , im not entirely sure of its purpose , might just be to help keep the bottle unfrozen in really cold temps. Might mean you could run with a slightly less concentrated screenwash solution , but the problem comes when you spray the screen and it freezes on contact :S been there and done that with 75% screenwash and 25% water. I now run neat under 6 degrees c . I.e. now.. not nice to see your screen go white at speed.

I too wanted to ask about the Heated Screen Wash feature.

So are we saying the washer tank is heated and the nozzles are heated?
What about the pipes in between the two? Surely they will remain frozen?

I was under the impression that that on the E it was only the heated nozzles that were standard.

I have it as standard on the E. However it works it is excellent in these freezing weather conditions to be able to clean your screen when all the salts are on the road.

I see you mentioned the banned words "C63" again....

The tubing is heated also

The tubing is heated also

How is that done?

 

[whitenemesis]

Trace heating controlled via the front SAM, as the nozzles, on at <5c and engine running

I 2nd that, -12 degrees C today and hot washer system worked a treat. Helped of course by a 50% mix of solution in the washer bottle.

#Yes, a good mix is more important.

Remember, the parts are not always heated so it will get cold in their and the expansion of the fluid can crack the pipes, bottles etc.

No , the E class has got standard heated bottle too.

Im running pure screenwash just now as it says on the bottle that its only good to -16 running at 75%. dont want the fluid freezing on contact with the screen.

Something to watch in this weather is the headlamp wash wipe and keeping the flaps clear and making sure they arent frozen. running screenwash too weak will result in those freezing in too as the fluid basically stops them coming out from their wee hidy hole.

Both my headlamp washer pumps needed replacing after the washer fluid froze over the cold snap last winter. Wasn't that expensive but an irritation nonetheless.

Fuzzer raises a good point above, did loads of miles on M11 last week in the snow and found the lamp wash heads froze in the bumper.
