Hello I have a C126 5.6L and the engine won't start. I press the KE-Jetronic sensor plate slightly with my finger and the engine starts. Can you give me some advice on what could be causing this?

Thanks for sharing the knowledge

Great video

Nice! Can you provide the actual details on how you positioned the zip-tie on the striker. The video skips over this step. The video is kind of grainy on my end so I cant really see the detail on the zip-tie's position.

i boght a another idle control valve you showed me before how to make it idle properly which it did since it got cold itdles to high is that normal ANY ADVICE HAPPY NEW YEAR ON MY 89 420 SEL

Hi Ralph.thanks for putting this video up.I have the W201 Petrol E190 and noticed one the vaccum lines is broken and going into the fire wall and It is totally disconect just loose in the fire wall. Would this cause idling problems and can you tell me where it's supposed to conect to. Any help would be appreciated many thanks

I have an 85 380SL and couldn't fix the high idle issue. When engine hot, it goes up to 12-1500 RPM. Took ICV out and cleaned, and it seems operateable with rattling when shake. But my ICV has no brass piece thread at the end to adjust the spring. How do I adjust it?

I have a w126 500SE. The car wouldn’t start, so I have just installed a new battery and it started great for the first few times. However it is now not starting again and the new battery has only been in the car a few days. I’m suspecting a faulty alternator. However the red battery light hasn’t come on in the dash? I’m going to jump start the car tomorrow and then disconnect the negative on the battery and see if the car stays on, hopefully ruling out a faulty alternator. But any other suggestions I could look at? Any help would be greatly appreciated! Thank you

Very helpfull video, thank you!

Thank you for this video. I' gonna give it a try!!!

What engine? Does it matter? Diesels the same?

Thanks for this video. I have a shake that is there basically all the time but is most noticeable at idle and lower speeds, such as reversing out of the garage. It is very inconsistent and hesitates but never feels like it is going to die, just is rough and a bit jerky. I've ordered insulated spark plug pliers that get here Saturday to do as you have as it seems like this could be the case.

Will give it try today! thanks Ralph

Hi Ralph, I found one of your Stray Benzes for sale. Would you be able to give more history on it? 87 300sdl. Thank you kindly.

Please sir….buy a camera tripod! I was getting seasick from your camera work. But otherwise a great and very informative video.

Hi Ralph, I enjoy your videos, this didn't work for me any ideas what could be the issue? Regards.

Amazing, thanks for the tutorial, wholesome too

I have a 1984 500 sec and the passanger seat stoped working. what do you think the problem is.

🙏 thanks for sharing, only one more detail, can I do this without removing the driveshafts? . . . or the diff?

I have heat but i can't get the fan to blow.. the only time it will blow is on a cold morning at first start and only for about 30 seconds and then it will not not blow again

Hello friend, greetings from Spain, with a 1990 560 SEL. The heating and air conditioning have always worked perfectly in these 12 years with the car. As you know, the 560 has a preheater as standard (I understand it is a thermal resistance type) that despite having cold antifreeze because you have just started the engine, if you select maximum heat in the climate control, hot air comes out almost instantly and yet you have the engine temperature completely cold. It's great. The fact is that yesterday, that option did not work for me nor the normal heating with the engine hot, only warm ambient air comes out. The air conditioning works well. I suspect that either the ECO push button or the other directional distribution buttons are failing or the temperature selector wheel itself does not order that valve to close the circuit more or less for more heat. Now that you explain those initial steps to review, I'm going to do it and in a few days I'll tell you. Thank you very much!!!

I`m working on a SL 350 V8 and I have a problem with cylinder no 4. makes a ticking noise, something like the diesel injectors do when the copper seal goes bad. New spark plugs, changed the lead, cleaned the distributor cap. When idling if I remove the lead to the No4 spark plug the ticking/puffing disappears. Could it be the injector seal that went bad?

Hey brother thanks for the video. I'm rebuilding my own injectors but I don't have a spare injector line to attach to. Do you mind sharing the thread size of the injector hard line on both ends?

Will they work in a 190e?

New belt , New tensioner squik at all times all bearings are good , I have played with the tension (from hard to soft ) still squiking , I don't know that to do anymore , I do not know the state of the damper , could that be? , but I don't know

Excellent! I can always rely on your videos as they are well explained with real life experiences on what's to follow.

The car doesn’t start early in the morning on rainy days. M102 mator w201

good job, tnx.

Thanks for the tip! Had the same problem with my 2.3 16V.

Hi Ralph, did you know the bolt size or part number from the tensioner (top one that screw into the aluminium block)

Tus for the video

Hi, I have a 1994 e320. Have similar issue, but I believe my car has a different system isn’t it? Any advice for that model?

Tak😊

The other day, I drove my 1988 420 SEL in very hot weather and parked it in the sun for about 40 minutes. When I went to start it, the car wouldn’t crank or make any noise when I turned the key. The accessories were working fine, and the battery is brand new. After an hour, it started as usual. What could be the issue, and is there a video about it? Thanks for the videos.

Just found your channel because i was searching for W126 advice and repair info. I've briefly looked over your playlist and you seem to cover alot of material on this channel. I too love Kent Bergsma's "Mercedes Source" but alot of his repairs get closely. Your channel will compliment his in that regards and i personally thank you for taking the time to make these videos. I personally love the 300SDL and 350SDL cars for their 6 cylinder diesels. Nice to see one previewed.

Good information, thanks! I am wondering if this might be a cause of the loud "CLUNK" and jerking when shifting from Drive to Reverse on a 1985 380SL. It does not happen when shifting from Drive to Park, or from Park to Drive. And it doesn't happen all of the time. I was told it is vacuum-related and a standard transmission servicing won't solve it. Thank You!!

Which website has this information?

This was a good help for me, just bought a 420 sec with nonworking seats. Thanks a lot.

Is it clockwise or anticlockwise to richen the mixture??

Been looking for this video for a while. Thank you!

A correction to the title. The rear lower control arms in a w124 are different, as the implemented the new multi link suspension system! but a good video non the less!

Hi @straybenzes, I have a 1991 300 CE 24v. It revs fine when it's cold, but when it gets hot, it starts hesitating and lacks power at low revs, although it drives fine at higher revs. Could this be the cause of the issue? I added fuel cleaner yesterday and drove for an hour, and the problem nearly went away. But when I started the car an hour later, the issue came back.

Thank you for these videos. Very helpful

Can I have your mobile number? I have a car problem and no one has helped me.

Hi i have w126 M103 what is the reading on cam sensor ? And what it means if there's no reading at all? Thanks

I put new alternador but no charge the battery I have a mercedes w126 1990 350SDL 1990

Same basic layout as my W124 230E. My AUX fan fuse blows after a few minutes when running on full power (haven't checked on 1/2 power, no gas in A/C). The motor gets hot, possibly due to a high internal resistance or short circuit, then the fuse blows. I was considering overhauling, but thanks to your video, I see it's not really an option.

Nice sir, very informative. 🥳
