Great job!!! Very detail.
Thank you!
Did the repair today! Worked like a charm! I had no heat for 2 winters over a $50 part. The dealer told me the repair would take two days and cost over $1000. He told me something else completely different was wrong and that he’d have to take apart the entire dashboard and console. This video saved me $910. The asshole dealer charged me $40 just to look at it.
I Kiss your Heart that was the Best repair video i‘ve ever seen!!! 👍🏻👍🏻👍🏻
Did mine yesterday. Followed ur steps. Now I have heat!!! 😊
glad I could help you!
Splendid! Very detailed and educative job! Thank you!
Thank you very helpful love my w211 e320 cdi .
Excellent video ! Thanks a lot, that's a tremendous help. For others doing the same job, just note that the wipers can be difficult to remove and will require an extractor to come up.
Thanks for commenting! You're right about the wipers. I had luck with mine - they came right off
Cder Zed the wipers are tough to get off I found that if I put pressure on the blade so that the rubber was flat against my windshield that I was able to more easily pry it up.
Muy buen video, gracias por compartir conocimientos.
Great job Diesel. It is a right hand drive Marvin.
thanks man!
Great video! Thank you.
thank you! thanks for watching!
perfect,,can you show how to replace or remove crankcase ventilyation valve
Great video! All is clear all is available) One question: at the time of installation of the crane was off the control panel with hot air or whether its position internal stop-valves Thank you for your understanding
Ty so much
Great video. I did have a question though...
I am trouble shooting my car not blending temperature on either side (driver's or passenger's side) of my Diesel w211's dual climate control. it makes no difference if i have the temp selector dial on the climate controller in the 60° position or the 90° position, it blows ice cold air. Additionally, if i continue to turn the temp selection dial until i reach the "red" dot, the heat works fine. So there is no blending/mixing/ or regulating temperature to a specific comfortable setting.
Does this sound like the symptom you encountered that made you change this valve?
Nice job dog! My x GF had an E220. Did lots of work on it until she gassed me. Moved on now I'm a chubby Chaser! Cheers Mate
thanks!
Do you have to put more coolant in the reservoir because on the video nearly any coolant came out???
I have one under my brake master cylinder. Mines the uk version. Is that the valve? It's not in the same place as yours.
Sir I had a problem with ac in w211 when I press ac button it just ac off . I checked all fuses and compressor all of them good could know what's the problem
Hello . I have a w212 , I’ve made a long trip , and the heat stopped ! Recently I’ve changed the cooling hose !
Do you think that I have to make empty all the antigel and put a new one ; change the heater valve ? Or maybe you have another option ? Thank you very much .
How do you get the wiper blades off w219/CLS550 2007, after I take bolts off they don’t just come up? I’m stuck
Is this the same for 06 cls500
Where does the o-ring go on the valve
Did the failure of this valve also cause your upper radiator hose to not warm up aside from no heat?
does it this apply to 2009 e320 diesel?
Is E320 Mercedes the same thing
Only applicable to LHD, if you're doing this on a RHD the valve is located under the brake master cylinder and is a nightmare of job to do. Great video btwm
thanks!
What's LHD and RHD I have a 2003 e320 and I have the same problem my car is blowing air but not hot
Before I start this repair I'd like to have the correct size hose clamps ready to use. Can you either provide the hose clamp make/model / size info? Looks like a nice DIY repair but could end up with a mess without correct hose clamps. The ones and size you used look PERFECT for this tight job. Can you please provide detail on clamp sizes... thx
I used the old original Mercedes ones, they are very durabe. If you need the pinch-off pliers, you can get them on Amazon for 10 €/$Thanks for watching!
wanna cold, but driver side give me hot
can be that piece ?
thanks
2-zones or 4 zones?
Great Video, I have a ML350 with no heat in the cabin, but also no A/C
would my heater don't work because of the bad AC or I have 2 separated problems, lack of Freon and this Heater Valve??
sounds like two separated problems.
i have 2006 CLS500 2 times online got the wrong part 211 832 06 84 suppose to be 211 832 05 84 has an extra hose connector for the engine side single clip connector that has the rubber boot around it. My Paid Euro Mechanic friend adapted it with a plug & clamp. It last over 3yrs then the plug cracked & leaked. Had to replace myself this is were I got the same wrong part again, Found the correct one on Walmart online that shipped from amazon but it wasn't OEM and is Chinese knock off. I got the part in with the 2 clips connector to the Heater core on the firewall OK and electrical connector. The hard part is the single clip connector with the boot. I spent hours, It won't go in at all. There is a wide key slot on the bottom and a smaller on the top. The wide part on the bottom seems to be the obstructing key. I took pictures with my phone it matches the original slot keys.The guy in this video pushed it in easy with 2 finger. There's got to be some tolerance issue or I'm just not getting the trick of how to do it. My mechanic said it you get too forceful you could damage the heater core in the dash which is big money to replace. Has anyone had this problem or do I need to order the OEM part?
I have had same problem. It was easy fix until the new non oem part that fits on the 6pm side of the valve does not fit the water hose head. The two slots do not fit. I am unsure what to do, maybe shave off the nubs or find some way to rig it, or put the old one back on and get Mercedes oem part this time :(
Thank you, but I have a problem that the front air is cold and the back air is very hot. The problem is our summer is hot How cool it is. I want it to be cold
How much time to disassemble?, time to replace valve?, time to reassemble? I am trying to break up the repair because I don't have 3 straight hours to attempt this. Thanks!
should be done in 1.5-2 hours, if you are prepared and have the right tools for this job. the trickiest parts is to get this old valve out. Sometimes it's easy and fast, sometimes it takes some more time. Thanks for watching
👍
Was this operation done because there was no heat goi g i to the heater circuit?
I have that problem on my 2010 Vito but just can't figure if it has anything to do with the cabin air quality sensor.
Yes, there was no hot water coming from the engine to the heater circuit, because the valve misfunctioned due to a broken O-ring. your problem might be similar to this one otherwise it might be the electrical heater coil (if your car has one) ...this would be bad - costs a lot of money to repair, so try this valve first
DieselDog Thank you for answering! The problem with this valve system is that is plastic sealed. Not sure if I can take it apart.
If it was a blocked situation due to residue or about a month with the van parked, could the valve become stuck?
I've seen two valves so far that had the same broken O-ring. I also tried to open it, but the clips broke right off. It is not worth the time. Part costs only 40 $/€. In my car the this valve failed once, than worked again, but after one week it stopped completely, so I had to change it.
i have a problem with my e220 cdi 2003
the temp engine its going to 100degre after
i changed this part
thermostat
water pump
fan and checked for leaking there is no leaking water
can this part heater valve make engine goes higher
the fan turns on only when the engine temp is 100 degre
Hello, did changing this part solved the issue for you ? I have the same issue as you. Regards
Could a faulty Duo Valve cause one side of the W211 A/C to be warmer than the other?
I have the same issue and I was wondering the same thing
Same
