Ty for your video small creators like you in these obscure components can be invaluable for info with a project like this I know cause it's going to help me
Mate your so lucky you got the solinoid off without breaking the plastic. I went through 2 valves trying to get the solinoid off. Both were fused to the bottom plate.. Now the good news - despite the different size and part number, I took one of a late model w202 since it looked electricly the same - and it worked! So now have a second hand part that's 15 years newer!
Christopher Norlen-Holmes this was a recent replacement on the donor car. I know this from buying a brand new genuine MB one a couple years back and seeing this new manufacturer as the OEM. The originals back in the day were made by Bosch.
Hi bro. I have the same valve and I fixed it. Only water is leaking out of the coil and I couldn't find where it was leaking from. I know that the original reels normally have gaskets, but my reels were completely broken and I couldn't get a new one. That's why I 3d Printed it exactly the same. I also installed the gaskets, I think they should not miss the gasket part. But I'm pretty sure you missed it by the coil. I wonder if the magnetic core of the valves (the metal part that pushes back and forth) is leaking from the hole part? Because I'm pretty sure I fixed the bottom insulation gaskets tight. If I close the holes in this kernel, will it work? Because I can't think of any other possibility. It's also the solution.
Hi, I was delivered a Benz E200 W124 by the owner. He complained that there was no warm air blowing through the vents so I got to it with a run-down of all the climate control components. I'd had no prior experience with working on a Mercedes, so it took me some time to pinpoint the culprit, which was this dual valve. My question is, would cleaning it out make a difference?
i had one of those later valves with the integrated pump, i got one in mint condition for $15 off a parts car and gave it to a friend. I didn’t realise how valuable they are
Do you know how to bleed the duo valve on a 140 with an m104? It has an aux pump which needs to be primed I assume. I replaced the water pump and I think I have an air pocket in the matrix.
Did search for eletric components,my valve has just ohm in one pin,plub 3 pin,middle pin to the right pins has but to the left pin nothing. Someone repairing the solenoids alslo?
@@MMWA-DAVE thanks for the information. I have severval w124 . And would like to keep it running with little effort. Mercedes only sells me complete Duo valves. I think you Videos are great, because you can learn a Lot 👍🇩🇪
Mein Merc w202 ist ein '98 und hat das Kit über Ebay von einem russischen Verkäufer gekauft. My Merc w202 is a '98 and purchased the rebuilt kit through Ebay from a Russian seller.
I'll have to do mine I think. I have 500sec and my heaters are stuck on. I'm presuming it's duovalves I tried pulling it apart couldn't see what could've been wrong.
126 does indeed have either a mono or duo valve depending on heating setup used. 126 also has a separate box apart from the actual control panel which controls everything and is known to cause problems too.
@@MMWA-DAVE yeah all have to try an look up how to some tests and start eliminating stuff. My valves look different too. Big heavy magnetic things they were.
Faith Godwinked this rebuilt valve has gone into my restoration project w124. I expect it to work exactly as per the brand new one purchased for my other w124. I rebuilt this one because although it was recent build, it had oil run through it.
Faith Godwinked what you need to do is search for the kit appropriate to your valves part number. There are many valve variants and the kits are all different for them. All i did was search my valves part number and the kits came up
@@MrPhymed Oil scum collects in here from previous or current leaking head gaskets. When ever there is oil in the cooling system; this valve will suffer badly.
good morning my w124 has a problem, practically with air conditioning on from the central vents hot air comes out, and you can hear a click click sound every few seconds. what could be the problem
Graziano Zeus interesting. Well if you have access to one, you could try another control panel. All the electronics are inside it. If you have heated middle nozzles you will hAve the final version which will be in late version cars only (I’ve not seen this version before) i believe this final version also has a vacuum pod for mixing the air for the middle nozzles. This may also be an issue.
I cannot diagnose someons car problems from a 2 line sentance. Also I simply do not have time to answer everyones questions. I would suggest having someone take a look at your car if you are having serious problems with it.
Your detailed disassembly and photography are excellent.

Good you did rebuild surprisingly oil was probably good for valves
Excellent attention to detail as always !

Completely random questions - what brand / where did you get your k-jet fuel pressure tester? Looking to buy one

Hi, where did you get hold of the repair kit?
Seems nowhere to be found.

eBay. Search by valve MB part number on yours.

The divider plate all seem to pit in the same region. I built mine back up and resurfaced it on a flat surface.
'94 E300TD: similar unit... but with additional, third, "bean can"... Circulation pump... non A/C, electric sun roof.

bom dia poderia dizer de onde vem esses kit obrigado
My 1995 W124 monovalve has two connectors on it, not just one 3 pin connector. Is yours an upgraded PN or something?
David C you will have the automatic climate control. This duo valve is for the manual version with 2 temperature wheels
@@MMWA-DAVE ah, I keep forgetting.....thanks!
Have you got the link of the repair kit ? Thanks
Well its better than rust - Wear proctologist gloves - keeps your hands clean ;-)
brake cleaner spray?
eBay Link? Sorry, i am German, my english ist Bad... I have never seen rebulid Kits vor duovalves... Grüße aus Deutschland 👍
Meporfo 66 you must search by valve part number. There are many different versions and kits.

@@MMWA-DAVE That makes sense. I wonder why I didn't think of it 🤔
Use loctite 7070 when degreasing.
Bro, you needed to oil up the metal valves for lubrication!
No, I didn’t.
@@MMWA-DAVE Ah, thank you for the tip.
I do wonder though: where did all this original oil come from? Isn’t it part of the old lubricant?

Is that salt water
good morning my w124 has a problem, practically with air conditioning on from the central vents hot air comes out, and you can hear a click click sound every few seconds. what could be the problem
Graziano Zeus if you are getting very hot air like the heater is on when it isnt i would be checking that this valve is properly operating.
@@MMWA-DAVE ok thank you very much, but this happens with air conditioning on, if it is off it does not happen
Graziano Zeus ok then there may be an electrical problem. Is it the manual system as picture in my cars or the automatic one?
@@MMWA-DAVE
I have the manual climate with two wheels
