Help D-Jet Mercedes M110 280CE

Hi Mads,
I cant believe all your temp sensors and the MAP sensor, too are defective.
I still believe in a problem with the cable lugs.

The sensor 0 280 100 111 is 'type III' and much more solid than the other types.
Therefor it is avaible in used condition at a much lower price than the others. The risk in getting a defectice one is not too high.

But perhaps Volker can sell you a MAP sensor that really works 'with guarantee' cause he checks every part most intensive,

Repairing the sensor means opening it, maybe the coil is defective in total maybe can be repaired.
But then one must reassemble the sensor correctly - great risk it doesn't hold vacuum after that.
Then it must be readjusted - no other hobbyist than Volker can do this, as far I know.
Read about it at the D-Jetronic-Compendium here...

My advice: Buy another MAP-sensor, keep the defective one - one day it may be repaired.
Think you want to drive the car...

Did the test directly at the connector, without the plug.. Can do a video on the test..

Hi Mads,
we like videos...

It would be most interesting in which way all these components got damaged --- still can't believe all sensors are defective

And the motor ran before, or are you overhauling the car you got in non-working condition?

The car has not been driven a lot, because it runs pretty bad did an ekstra test today, the MAP secondary coil is still bad, when i test directly on the MAP.

Primary

Secondary


The air temp sensor is also dead i cant figure out what sensor is the coolant senso, its only the one in the mittle that's giving a reading when i messure the ohm..


But it's actually a pretty nice car, good shape.. Seen here with my 1971 350SL:

Hi Mads,

if the picture is correct, then you measure wrongly! Your multimeter is in range 200 Ohm when you try to measure a 360 Ohm resistance. No wonder it shows "1 ." indicating above range. Switch it to 2000 Ohm before you measure secondary coil. And please switch to 2000k when you measure against car ground as second test on primary and secondary coil.

Sorry, i'm pretty stupid The secondary coil is showing 361...
But now i don't a solution to my problem BAck to testing again

Mads..
