Merhaba Rosi,

höş geldin to our Web site. What car are you running and how did you get Rosi as first name. Does not sound like Istanbul at all. I know it is impossible to import an Oldtimer to Turkey.

If you want: I can bring one measuring gauge with me to Turkey mid oj July if you fear transport costs and customs.

Hello

I just saw your reply. I was out for vacation. did not get online.
My name is Juan. I use my wife ' s name as login name. we are Spanish descendants living in Istanbul Turkey.
Contrary to what you think we have many old-timers in Turkey. pls check the links ww.klasikotomobil.org., www.pasagaleri.com , www.keymuseum.com , www.atamanmuseum.com , www.rmk-museum.org.tr are a few examples.
Many people import cars from the united states and restore them.
the car I bought was a wreck which looked like a princess because of the good paint job it had. like a trojan horse.
anyhow I have restored the MB 350 SLC 1972 to a very good condition by using original parts from DB. in the power point presentation you can see the transformation.
I have a problem with the engine. I am a member of www.107sl-club.de . I wrote to them and they asked me to make a tip to toe examination to find out what is wrong.
the whole engine electrical cable system was re-manufactured locally by using original sockets which I bought from Sweden from a Bosch parts dealer. the manifold pressure sensor was rebuilt in Bosch Germany. I did not touch the ECU as many say it is very solid. the Drosselklappenschalter' s electronic board was replaced which I found on the internet. The sensor on the air filter was replaced with an original one. The pressure of the fuel was not right as I had the wrong pump. This was replaced with an original one recently. Now the pressure reads exactly 2,0 Bar (see attached picture). I did many other things. My mechanic tells me that I need to change the Impulsauslöser. He has a lot of experience with such cars as he started in a MB shop in Istanbul at a very young age. Before replacing the part I want to make sure that it is the problem. If you give me the dimensions I can have it done here in the industrial zone. Since it took me two years to fully restore the care I have met many talented people who create wonders with their hands.
My problem is when I push the throttle just a little at a certain level the engine starts to choke (and 1500-1800 rpm) this repeats around 3500-3800 rpm as well. but when I hit hard on the gas pedal the problem goes away. the spark plug cables have been renewed as well.
If you have any ideas pls let me know
regards from Turkey

Hello Juan,

what you tell me does not sound like the trigger contacts. but you can easily verify whether they are working: Just touch them with your hand while the engine is running. You should feel them vibrate. If necessary you can also use a stethoscope like this one . If you feel or hear single cylinders not running, please report back.

I do know Istanbul very well, I lived and worked there myself for several years as General Manager. Still I often make my vacation in our summer appartment on the Aegean sea. I even was there when the military coup happened. And I can tell you that Turkey does not allow import of cars older than 3 years any more since many years, not even Oldtimers. So everything that is in the country can be used, no new ones can be imported. That is why old and new cars are much more expensive than in Germany. Of course you as a foreigner can import a car. But then you cannot sell it as only foreigners can run it with a special number plate like 34 MD xxxx . It is a pity.

Did you verify that you have the right components in your car (See appendix A)? Plus compression, valve play, and ignition dwell and timing test at idle, 1500/min and 3000/min. Those are the prerequsistes to start with. As we already have very limited knowledge of D-Jetronic in workshops in Germany, it must be even more limited in Turkey. Don't listen to "No problem" and "we will find it". You better check yourself or oversee what your mechanic does. What you describe to me sounds like the typical "Change all components" until we find the error. You already changes MAP sensor. Now they typically demand new trigger contacts and finally ECU. If he was really experienced he would know how to diagnose Trigger contacts. I admit that ECU is more difficult.

Hi Juan, Hi Volker,
the following is misunderstandable (I marked the sentence).

You can feel or hear the injectors working - not the trigger points.
Juan, I just sent you a figure for producing the tool.

Regards
Norbert

Hi Norbert,

that is correct. I meant that you can feel the tickering injectors.

Hi Dr. D-Jet,

Thank you for the dimensions of the 'tool'. I had it made. Later I tried to adjust the contacts.
Everything worked well. Thank you again. But my problem still persists.
I will try to listen to the injectors to find out If they are working.
In the mean time I have started to gather the info on the D-Jet parts used in my 116982 engine. then I will start the test for each one of them. by separate message I will try to explain my problem

in the checklist you have mentioned the item 'Unterdruckversteller'. I have this item on top of the Zündverteiler as an additional part attached. But there is no number on this part. How can I know which version it is and If it is working?

Hello
is there an opportunity to get the dimensions of an axle to fix the trigger point to an MB 450 SL with D-Jett?
Kind regards

No, Rudiger, I removed the dimensions some years ago.
And never published the dimensions of the revised tool I produce nowadays.

Some guy once published my name, full adress, phone in an U.S.A. forum. I didn't like this and withdrew my publications.

Every member can send me his email-adress by P.M. and I will send dimensions and instructions.

Joakim, you will receive a message soon...

Norbert
