Hi Kerim,

I fear I cannot help if you do not know how to measure that contact 12/47 and 17 is closed on throttle switch by loosening those 2 screws and turning it. I have no video showing that. If your mechanic also does not know, it is time to change him.

Thank you for your answer. We met your Turkish friend. Our mutual friends are out. I am grateful for sending him my number. Besides, you are very right, but unfortunately they do not know these engines (d jet) in Hatay. Should I remove the black cap on the ts during measurement?
thanks, best regards

Hi Kerim,

no you just remove electrical connector and use a multimeter in resistance measurement. Now loosen upper and lower screw and turn housing until you see 0 Ohm. Turn 1 tick mark further in 0 Ohm direction and fix screws. No magic and no need to open housing.

I forgot to ask what is the reason for focussing on throttle switch only. You have seen my checklist ?

good morning
thanks, I will read it( check list) to morrow.
I have another problem.
I last used the car on Sunday, from Sunday until today, the car was always in a closed place for 3-4 days. I tried to start the car 8 -10 times but it doesn't work at all.During the check I made at the mechanic last week, we noticed that the thermal timer ( termozeitschalter)was not working, the relay that came to her may be broken or she is broken.Could the thermal timer be the reason why it doesn't work? Does the thermal timer have a brain-related function?
These are the questions that come to my mind.
Since the thermal timer and the brain cannot communicate, is it possible that the brain does not send more fuel to the 6 injectors when it should be sending more fuel at the first start?
best regards

Hi Kerim,

thermotime switch is hardly active in your region and if only once. It is activated while cranking engine. It is electrically heated and when it reaches 35°C it will not operate any more. Its effect is only for a quicker first start on cold engine. YOur engine must start without - just a little slower.

Have you measured fuel pressure?

hallo dear dr volker
yes I measured fuel last week.(2bar)
