Mercedes Benz 190E W201 | Rough Idle Fixed? | Leerlaufprobleme Gelöst?

- What‘s up everybody? Welcome back to my channel!
Finally the last episode on the rough idle series. After replacing the hoses, I focused on the ignition and found the fault. The spark plugs! They were so toasted that it was a miracle the car ran anyway
What I did in this episode is following:
- Cleaning the air flow meter with valve cleaner
- Engine flush
- Oil & filter change
- Spark plug change
- Sanding the connectors of the distributor cap and rotor
Now the car is running smoother than ever. The only problem is the engine won't start when it's cold. As soon as I find the problem, there will be an update on this. If you have any clues, let me know in the comments.
Anough talk, enjoy watching!

Thanks mate! very helpful.
Thanks for videos!!! you help me a lot❤🔝
Thanks for the nice feedback! Happy to help.
Thanks buddy
For the bad ignition check your battery, OVP relay as well
One of the causes of a bad starting on these cars may be the Kjet injection, it is known for having difficulties to start if you dont use the car too often
Top bitte mehr vom 190!(:
Vielen Dank! Es kommt auf jeden Fall noch mehr! :)
👍🏻👍🏻👍🏻
Gut zu wissen dass man nicht alleine mit dem Kaltstartproblem ist 😂😂❤
Wir sind eine große 190er Familie mit einem Auto voller Baustellen 😂 Wie sagt man so schön - geteiltes Leid, ist halbes Leid
My 190E was just not starting when it was cold would take like 2 minutes of cranking to start it then it would run fine and start fine when it was warmed up, just turned out to be the OVP Relay
Thanks for the hint, Versoh!
Did it look like your ovp relay have issues? Mine looks brand new but I have poor idle until it warms up then goes fine
Welche Größe für die Zündkerzen ? Also der Schlüssel
hey man i have the same car i really like your steering wheel where did you get it from? and you have great videos keep it up
Thanks Steven! I found it on eBay. But mine was a second hand one. There was no new available.
cold start? try checking / changing the OVP relay behind the battery.
Thanks Shahazlin!
Did you find the issue with the cold start warm up issue? I'm having the same issues with my 230e
Not yet. The issue was more or less fixed by the good weather. But I guess I need to dig into that since it’s getting cold again. Many persons told me that it could be the OVP relay. Maybe I will start checking from there.
Hello 👋
I have a 87 190 2.3 and would like to know how you keep your engine looking so good! It's immaculate!
New subscriber 👍💕
Thank you 😊

Hi, sorry for the late response. To be honest I just wipe down the dust with some regular cleaner. But in real life it’s not that clean as it looks on camera. Maybe there will be a future episode about an engine bay clean. Appreciate your feedback and support! Regards from Germany 🇩🇪👋🏼

Because of the age of my Mercedes, "1987"
there is oil build-up on parts of the engine that I know can be cleaned up - I just don't know the safest way to do it.
It would be fantastic if you did a video just on cleaning!
Thank you for answering my question 🤗
Cheers 🌟
Did you figure out WHY your plugs were "fouling" up with soot? I've been told that's a fuel mixture issue but I'm not sure that can be adjusted with KE injector systems. Low compression in those cylinders maybe?
In my case, the valve stem seals were worn and needed replacing. I have another episode for that. The plugs are fine since I replaced them. I hope this helps!
Great vid, brother!
Has your car always starte rough when cold?
Thanks Bro! This problem is new.
@@KUNIQUE interesting! I hope you can find the reason for hard cold start!
Thank you. I will focus on it once I sorted out another major issue. It seems that my locking system is dead and I can’t refill fuel 😅
@@KUNIQUE der Tankdeckel hat eine Notöffnung 🙈 wenn du im Kofferraum die Verkleidung abmachst ist dort ein Seilzug oder so, den man ziehen kann. Oder hab ich dein Problem falsch verstanden?
Leider ist die Notöffnung auch defekt. Dieser rote Knopf hängt lose drin und entriegelt die Klappe nicht. Muss das ganze Teil auswechseln.😅
My 190E idle vibrate when I turn on the AC but smooth when AC off. Do you know the possible cause?
Sorry, I don’t know what the reason could be.
Could be the OVP relay, when they go bad they can cause all sorts of problems. Does you (ABS) lamp light up occasionally?
@@00xxsorenxx00 Thank you but mine don't have ABS.
@@user-kc5sj5pv9k ah I wasn’t aware 190Es came without ABS!
@@00xxsorenxx00 It was an option. Didn't come as standard.
kaltstart/coldstart problems = ÜSR/OVR (überspannungsschutzrelai/overvoltage relay) oder/or kaltstartventil/coldstart valve...ÜSR/OVR einer der häufigsten probleme/very commen problem...sonst kann es auch/ it also could be = benzin druckspeicher/petrol pressure accumalator...
Vielen Dank für die Hinweise, Paul. Werde ich beim Prüfen beachten. Sollte mir auf jeden Fall helfen, den Fehler zu finden 👍🏼
@@KUNIQUE benzin druck sollte soweit mich erinnere mit motor abgeschaltet sprich ruhend 2,5-2,8bar aufrecht halten....sonst druckspeicher defekt... und die benzinpumpe bei laufenden motor etwa 5 bis 5,5bar aufbauen...fürs ventil,am besten kurz abschrauben aber angeklemmt lassen und in ein becher hängen,kurz motor starten +schauen ob einspritzt...falls nicht kann es aber auch das ÜSR schuld sein anstatt ein defektes ventil...ohne üsr ist dein auto quasi in einem analogen notlauf...würde auch mit dem üsr bei der fehlersuche anfangen...am einfachsten ist probeweise eins rein das bekanntermaßen funktioniert von einem anderen w201 o.w124 ansonsten lästige durchlassprüfung des relais mit einem multimeter...aber zu 95% ist eins der drei kanidaten die uhrsache für dein problem...
Danke für die ausführliche Erklärung und Aufschlüsselung! Ich werde berichten
Meiner startet genau so bescheiden wie deiner.. hast du schon irgendeine Vermutung? Kaltstartventil oder so? Tolles Video MfG.
Leider noch keine Vermutung. Ich werde aber mal den Kaltstartventil, Benzindruck und Überspannungsschutzrelais prüfen. Muss halt nur auf gutes Wetter warten. Aber sobald ich eine Lösung habe, werde ich es hier teilen. Übrigens vielen Dank für das nette Feedback.
@@KUNIQUE Alles klar, ich freue mich schon auf das dazugehörige Video :)
überspannungsschutzrelai, kaltstartventil, oder druckspeicher der ke...drei häufigsten kaltstartprobleme beim w201...bei meinem war es das relai...
@@KUNIQUE also bei mir hat es am Üsr gelegen.. jetzt springt er wieder richtig gut an 😊
Freut mich zu hören! Hast du das ÜSR komplett gewechselt oder nur die Sicherung?
What shocks do you have on your ride my friend?
Honestly I don’t know. I guess the stock ones. I will see them when replacing the springs, which will come soon 🙂
@@KUNIQUE I’m getting my front ones replace with bilstein along with a few other things.
Hello, how to remove the rotor? Just pulled?
Hello Detri, you just have to pull.
@@KUNIQUE ok thank you
Is the rough idle fixed or still experiencing problems ?
The rough idle is fixed. The reason was the carbon on the spark plugs. But it seems it builds up some carbon again. I need to figure out what the issue is.
@@KUNIQUE Good to hear ! Hope you can find the problem with the carbon build up.
Check the Cold Start Injector.
Will do. Thanks for the hint!
Hello! What motor is your Baby Benz?
1.8 or 2.0??
Great job! 👍
Thanks Jacob! It’s a 2.0.
Never spray inside!! Use brush and apply on the brush and clean.That’s why you have a bad start
It's probably the OVP relay
Thanks Pepe!
Interessante questi video della Mercedes 201, sarebbe opportuno che fossero accompagnati almeno da una scrittura in italiano.
GRAZIE
The condition of your spark plugs looks like you have leaking valve stem seals. When the car is hot the oil will be more fluid and leak past the seals and foul up your spark plugs. Once the heat and carbon that are on your plug cool of overnight, it becomes a thick sooty coat over your plugs which may be more noticeable when the engine has sat overnight or is cold. Until the engine gets to operating temp again and is able to burn off most of the thick coating until the next time the engine is cold. The cycle continues and will become worse over time as the car tries to compensate by dumping in more fuel and soaking your pistons and creating an extremely rich mixture which will eventually clog up your catalytic converter and you won't be able to accelerate past 70 mph.....while only getting about 10 miles per gallon. Ugh, yes, a very viscous cycle indeed. It's been several months now, hopefully you've gotten this sorted out.
Hello Britanny, thank you very much for the good explanation and the valuable tip! In fact, I recently had to change my catalytic converter because it was clogged. The fuel consumption and the performance don't seem entirely normal to me either. It could actually be the valve stem seals. I will definitely do that soon. Thanks again!
@@KUNIQUE whats "the normal" mpg for this vehicle
@@rodrigosolis3127 i get 40 mpg 190e 2.6 , also did you do the valve stems
