Hello Andre,

If the engine control unit does not receive the speed signal, the anti-kickback function of the control unit will not work, and the car will tend to jump or "kangaroo."
The speed sensor is located on the transmission differential, so check the cables and the sensor there.

Best regards, Rainer.

Hello everyone,

I have another question. After I deactivated the AGR (Abgasrückführung), my car ran quite well for about 1000 km. Now, it's starting again where the car doesn't run with full power.
As Ulf told me, I once checked the intake manifold for contamination and found a layer of oil about 5mm thick inside. But that's not all! If the two-way valve that regulates the vacuum to the EGR system fails, does the EDC (Electronic Diesel Control) then go into limp mode?
"Something isn't right; I'm also having problems when braking. It's not that the pedal gets soft with repeated pumping; it's the opposite. The pedal gets harder and harder. Then, after about a minute of not braking, the pedal becomes soft again. Could the vacuum pump be defective? However, if you disconnect the hose that runs from the pump to the two-way valve, you can feel that the pump is indeed creating a vacuum. Maybe it's not creating enough?"

Okay!
I am waiting for your answers.
Best regards, Reuselkopp.

That sounds like there's air in the brake hydraulic system -> you need to bleed the brakes!

Best regards,

Hi,
But if there was air in the brake hydraulic system, wouldn't the pedal feel softer and not harder?

What causes the EDC (Electronic Damping Control) to go into emergency mode if my two-way valve is broken?

Regards,
Reuselkopp.

Which valve are you referring to?
If an emergency mode is activated, an error code is stored -> read it out.

Best regards, Rainer.
