That is either the blower motor needing new carbon brushes or it is the motor resistor. The motor is most likely it.

Cool! Thank you.

The US version did not have that option. If it is electric then you can start tracing power to it. The temp dial is rock solid. I would look for the simple stuff first. The aux water pump behind the removable fire wall can sometime lock up and if you are unlucky they have been known to fry the controller. Good luck!

@straybenzes Thank you very much for your advice. I didn't know that in the USA there was no pre-heating option (I understand that mine must have one because as soon as I turn on the V8 in winter, after 15 seconds I have hot air and obviously it's not coming from the engine because it's not warmed up yet). I will investigate the power supply to the pump and valve. I must also say that my car doesn't have the famous additional programmable Webasto heater. That was optional on the 560.

Hmm. I seriously doubt that's a seal problem. Tough to diagnose from remote. What is the compression on this engine? Ok?

That would be M12 x 1.5

Yes and that is assuming that no one messed with the original set up.

@straybenzes thank you. No, I'm trying to keep everything original except lights

@@WhiteEagle76771 👍

You can use a strobe light to figure out if the dampener has an issue. Extreme misalignment is rare but possible. The other thing to look out for is to make sure each pulley is easy to spin. Unusual load can cause belt squealing.

Thank you very much.

Well, that could be caused by a multitude of reasons. From afar this sounds electrical related, but it is all but impossible to diagnose from a remote location.

Glad it helped

Glad it helped.

That's a M8 by 25 or 30mm screw with a 13mm hex head. Best, Ralf

🙂

That model should still have the KE Jetronic injection system installed. 1996 came with big changes as OBDII made its debut on all cars.

@@straybenzes well, mine is different from the one on the video, no big air filter on top

@@PASTOOSHENKOCARS Oh, yes, this most likely has the Bosch Motronic installed on it. That is indeed a totally different system and I am not familiar with that one (yet)

@ I see, thanks for your reply though

@@PASTOOSHENKOCARS 😶

Yes!

I could be wrong, but these are the symptoms of the starter contactor going bad. If that happens again take a multimeter and measure the voltage on the violet/white wire on the motor starter relay if it shows 12v when you have someone turn the ignition switch to start. If there is power the starter will need freshening up. If there is no voltage it can be the starter lockout switch attached to the tranny shifting mechanism. You will need to safely jack the car up to get to that stuff. Good luck.

Thank you!

Thanks! That can indeed be the modulating valve on the drivers side of the gearbox. At the same time it can also be a few other things like clogged screens/passages in the shifting block within the gearbox. Good luck!

Hi there. I put them into the video description. Here is one of them: www.benzworld.org/attachments/mercedes-code-descriptions-pdf.454999/

Glad it helped you.

I believe it is counterclockwise.

@straybenzes Thanks!

@@waitwhat-qg9bc 😃

Glad it helped.

Thanks

Usually it is the other way around with the EHA aging it tends to cause stalls or no power when cold that gets better as the engine warms up. This could also be the idle mix screw needing adjustment. Did anyone mess with that lately?

@straybenzes I tried adjusting that, but it didn't make a difference-maybe I did something wrong. I'm experiencing a lot of misfiring, and when I press the accelerator halfway down, nothing happens right away. After a few seconds, the power kicks in again. I'm planning to check the fuel filter and pump maybe that's the issue. It's like I lose power if I press the pedal too hard or too quickly.

@@nicholasmablad2019 yeah that does not sound good. If the idle mix adjustment does not alter engine rpm than there may be other things going on with the fuel system. Start from the tank all the way to the injection system. Measure fuel pressure and differential pressure while you are at it. If the car sat for a while make sure to check the tiny filter in the fual distributor fuel intake. Good luck.

Thank you!

Here is one source and there are many more like it on the internet. www.ebay.com/itm/156423487035?chn=ps&norover=1&mkevt=1&mkrid=711-166974-028196-7&mkcid=2&mkscid=101&itemid=156423487035&targetid=2276391439863&device=c&mktype=pla&googleloc=9189555&poi=&campaignid=21781070863&mkgroupid=171979889201&rlsatarget=pla-2276391439863&abcId=10048875&merchantid=5426806121&geoid=9189555&gad_source=1&gbraid=0AAAAAD_QDh-frMC4Bb7EM9vNjtPk5uSmO&gclid=Cj0KCQiA_qG5BhDTARIsAA0UHSKrV-VO4dUtLhvtwvdD0VN0jQPLoQXwbmIh9FJs7Y4uiXDyuPT1oa8aAswrEALw_wcB

Please advise me

Go ahead and hit me up right here.

For the crank shaft sensor it is 800 ohm to 1200 ohm. Set your meter to 1K Ohm and bolt the sensor back in place. You measure from the end of the coaxial wire where it plugs into the EZL. For the cam shaft one I am at a loss as I am not aware there being one for the 03 from 86-90.

Is the battery ok? Was this a brand new alternator or refurbished one? What is the voltage before start and during engine idle?

Great job! Glad it helped you

Glad it helped you

There is no shortage of vehiecles who have been used and abused needing lots of time and money

Glad it helped you!

If that only happens with a cold engine it would be the starting fuel injection system or at least one of its components. It's the blue plug at the top and very front of the engine. It actuates a small solenoid valve connected to a fuel injection nozzles that sprays a little extra fuel into the intake during a cold start. It should have power upon starting and when you disconnect it during a cold start the engine speed should drop. That is however only one of a few other issues that could cause your symptom.

Wow. All the best!

Thank you and I have a whole bunch of people saying the opposite. All the best.

Thanks for the tip. The cheapest is still to replace the rubber diaphragm in an original valve insert.

😁

oof. Yeah, I have seen plenty of rodent damage in the engine compartment. Did the rat also get into wiring? The only thing I know to do is what you have started doing: trace the lines and make sure that they are properly connected again.

@@straybenzes Thank you. I'll just have to see if I missed a chew hole somewhere and check all the wiring too

@@straybenzes have you done a diesel purge before, and if so how do you keep (on a w123) fuel from pouring steadily out of the hard return line that attaches to the cigar hose going to the main filter? I need to also change the fuel prefilter but I can imagine the fuel is just going to pour out. Is there a way to stop that siphon action going on?

@@IshawooaPass Well, I am an old fashioned Diesel mechanic and have not attended the Diesel Purge church. Sorry for not having any advice to give to you.

@@IshawooaPass The best of luck to you!

Sorry for that!

Questions? Which one did I miss?

Oh cool, finally someone who does not like what I am doing. You rock!

I have only used US market parts and not from MB. You are better off going to your MB parts dealer and they will tell you what you need. You have a much better chance to get somewhere with that - here in the States most dealerships have no clue anymore how to work on these old cars.

​@@straybenzesI'll find out here. thanks for the information. greetings

@@frederiklansu270 The best of luck to you!

That is yet another new one I have not heard. It is worth a try for sure. What do you do with the waste water? How do you make sure that absolutely no water is left in the CV joint?

@@straybenzes The type of water does not matter, the important thing is to place the pieces in boiling water whose temperature exceeds one hundred degrees Celsius Leave the dirty pieces in the pot that is boiling intensely due to the fire being lit under the pot for a period of not less than 15 minutes. You will see the dirty pieces very clean We do this with engines that are dirty and contaminated with oil, sand or dirt Do this this way and you will thank me, my friend Remember that the best way to remove grease is boiling water🙂🙂

@@loaialtmiimi4426 Thanks!
