I broke these connectors while doing valve covers and breather covers on an M112 and M113. Here is the link to that video (M112, M113 Valve Cover Gasket and Breather Cover Reseal): th-cam.com/video/NxBlFhhVXR8/w-d-xo.html Thanks for watching!
This is one of the best produced DIY Mercedes maintenance/repair videos I've seen! (And I've viewed a TON over the years) The up-close views, the zoomed in and paused parts... Wow!
Well, thank you - I know that it can be very frustrating and discouraging when electrical connectors break. But they can be repaired! Thanks for your comment, and thanks for watching! : )
Excellent video and presentation with step-by-step instructions on how to do this. Love your patience and ease of doing this. Replaced my spark plugs, DIY about two weeks ago on W219. The connector clips break off very easily due to brittleness from the heat over the years. My car is about 15 years old. This is the first time I have had the problem with a broken clip not staying in place to the connector. I've had it happen on my other cars with no problem. I put wire tape to hold it in place for the time being. This is on piston one misfire on my engine vibrating heavily because of the broken connector not staying stationary. This video was very helpful. Now I need to purchase some new ones and replace. Thanks for showing how to do this job. Very nice.
Yes, that's what I was worried about, too -- the connector coming loose, for example on bumpy roads. And they are so brittle: I broke all six of them doing a W163. I needed them quickly, so I bought them through my local MB dealer: I found that if you use the "buy online, pick up at store" option you will get a lower price than if you just walk in and order them. Good luck!
I have just done this on my car and I have to tell you that if the plastic is too old it will break very easily. So make sure you hold the wires in a firm position before you try to break the plastic. Older versions of this part may have a plastic cover that the newer ones don't.
@@felipemiranda4296 Wow, that's great! Well done replacing your EGR valve. I'll have some new W163 videos up within the next few weeks (valve covers and breather covers, oil cooler seals, and water pump). Thanks for watching! : )
love your channel ! Please , its common issue in ML 163 -blend actuator for hot-cold shift . If you have to do the repair or change, could you do a video ?
@@L35inColorado With a great respect to you, have already watched it, it is really smooth and perfect job ! But i think the actuator in my car just stuck in cold , it goes actually between cold and neutral (white zone). Should i demount all the dash board ? I want just make a tap on it a couple of times, can i do it without entire dashboard removal ? Thank you really for your time !
@@havenoname123 I understand, because taking the whole dash is a big job (not too difficult technically, just lots of steps!). As far as I know, the only other option is to go in through the passenger side airbag panel: check out this video, maybe it will help. Good luck!: th-cam.com/video/SBLIdQXm9fo/w-d-xo.html
Is it necessary to disconnect the battery (negative, positive or both) before replacing these connectors? All of the clips are broken. Could this cause a slightly rough idle?
No, it is not necessary to disconnect the battery for this repair. If the broken connector clips are taped, or otherwise secured, then the electrical connection will be good, and they should be not a cause of rough idle, per se. But, if any one of these connectors is loose or vibrating (and therfore interrupting spark for a cylinder), then yes, it could certainly cause rough idle. I hope that helps - good luck! : )
I see that getting a used one isn’t gonna work cause I’m gonna have to break those tabs in order to pull the connectors out and if you have to break tabs it obviously won’t hold on my already broken one so you have to get a new one or can I splice the pigtail?
Yes, you can always splice the pigtail; just note that since this is for ignition, you will want to be sure that you have a very good (low resistance) wire splice in that case. The alternative is to buy the new replacement part (as shown in the video), because, as you point out, attempting to replace a broken connector with a used connector is not likely to work since the used one will probably break, too! It is unfortunate that MB used such brittle plastic for these connectors, but at least there are replacement connectors for a reasonable price. I hope that helps - thanks for watching! : )
My connectors look different and does not have a mercedes part number but rather it says CODE i 2868. I have a 99 ml320 m112 engine. What is the part number of your coil pack? Mine is A000-158-73-03, just to see if that same connector can fit mine. Great presentation and voice modulation BTW.
I can't check the part number of the coil packs right now, but using the part number you gave (A000-158-73-03), that is indeed showing as the old part number for the coil packs used on the '03 ML350 and '05 ML500, which are now part number A000-158-780-38: mbparts.mbusa.com/oem-parts/mercedes-benz-ignition-coil-000158780380 That page says that the part number above (A000-158-780-38) superceded your part number (A000-158-73-03), as well as A000-158-78-03 and A000-158-78-03-64. Perhaps you can give your dealer a call and double-check that the connector will fit: typically when MB changes a coil part number as a replacement part, the old connector will fit the old coil and the new coil, but you're right to notice the difference, and so hopefully the dealer can sort it out! I hope that helps -- good luck! : )
Hello there, I need to change some on my m112 engine......what type connectors are they? They are really expensive to get them from the uk, something like 20£ plus shipping,, can yuo reccommend a web site for purchase? thank you!
Haha! Can you imagine if the brain surgeons was like.."Okay, so we'll just break this part here...alright that's good -- now we'll jam this big screwdriver right in here real hard..." LOL! : D Thanks for your comment, and thanks for watching! : )

Good Luck with your Repair :-)
It happened exactly the same to me , now my car is shaking at idle sometimes while driving like a misfire could this possibly cause that?

Absolutely stellar, doing this exact job and didn't want to just start breaking stuff without being sure!
Absolutely FANTASTIC !! Thank you so much ! My Mercedes has been down for two weeks but now I should be good to go !!!
You’re a fantastic human for creating and posting this. Thank you.

Excellent 🎉 just got done on my sl500 super low miles replaced all breather hoses and valve cover this is next thx
Outstanding! To answer your question - no, you don't need to disconnect the battery for this job. Good luck and great job keeping up your SL500! : )
Thank you for this valuable tutorial. it was very helpful for me since i didn't find a similar one to work on my MB.

So you’re telling me that lazy is expensive but effort makes everything more affordable and possible

@L35inColorado thanks for the reply as in low resistance what does that mean. If it's getting full voltage?
I wish I could find connectors for my W202, C230 as well.
My connectors look different and does not have a mercedes part number but rather it says CODE i 2868. I have a 99 ml320 m112 engine. What is the part number of your coil pack? Mine is A000-158-73-03, just to see if that same connector can fit mine. Great presentation and voice modulation BTW.
I can't check the part number of the coil packs right now, but using the part number you gave (A000-158-73-03), that is indeed showing as the old part number for the coil packs used on the '03 ML350 and '05 ML500, which are now part number A000-158-780-38:
mbparts.mbusa.com/oem-parts/mercedes-benz-ignition-coil-000158780380
That page says that the part number above (A000-158-780-38) superceded your part number (A000-158-73-03), as well as A000-158-78-03 and A000-158-78-03-64.
Perhaps you can give your dealer a call and double-check that the connector will fit: typically when MB changes a coil part number as a replacement part, the old connector will fit the old coil and the new coil, but you're right to notice the difference, and so hopefully the dealer can sort it out!
I hope that helps -- good luck! : )
Hello there, I need to change some on my m112 engine......what type connectors are they? They are really expensive to get them from the uk, something like 20£ plus shipping,, can yuo reccommend a web site for purchase? thank you!
My connector does not have any of the plastic tabs. So how do i get the pins out?
Hmm - I'm not familiar with what you're describing, as I've really only seen these styles on coils. Is it an aftermarket connector?
Put w211 in the title too
If I ever need brain surgery, I’m giving you a call. Just sayin.
Haha! Can you imagine if the brain surgeons was like.."Okay, so we'll just break this part here...alright that's good -- now we'll jam this big screwdriver right in here real hard..." LOL! : D Thanks for your comment, and thanks for watching! : )
