Hello. . If there are serious errors in the engine management system, the velvetronic system is turned off. The electronic throttle system is activated. The engine starts working with discharge in the intake manifold. That's why there is a difference in compression. . Since both phase regulators hav...
Hello.
The duration of the injector pulse after entering the idle mode is clearly underestimated .
Possible cause - leaky intake.
Or - incorrect readings of the air flow meter.
That's about how it should be with a hot start :
Hello.
The code P1174 is not related to the crankshaft sensor - camshaft sensor pair.
The code is related to the need to reset the ECU adaptations.
Try resetting adaptations with the scanner.
Hi.
The flap is controlled by a PWM signal.
The control is stepless.
PWM=5% closed, PWM=95% open.
So if you want to have an M-Bimmer for F30 ( ), you should apply PWM=95% control to the pin1 violet wire.
Forever and ever.))
Such a change in the signal on the CAN bus can trigger a pulse energy consumer of sufficient power. There is no such consumer in the ECU Gear selector module. In the ECU TCM - there are (electric valves). First of all, you should check again the reliability of the contact pin8 TCM, measure the volta...
Hi.
You need to determine which of the electronic components introduces distortion into the signal form.
To do this, you need to turn off the CAN POWERTRAIN ECU - one by one.
This can be done on the CEM module connectors C and D, or on the CAN 53/352 and 53/353 cross.
The fact is, that very often the timing of the injector at starter speeds ,differs from the timing at RPM idle and at medium speeds. You need to make sure ,that the actual position of the piston in the TDC ,matches the marks on the pulley. . You can look at it this way. The decrease in the amplitude...
Hi. The ignition timing is very late. Much later than the TDC. This is probably due to a mechanical shift of the reference disk. . The engine speed when rotating the starter is approximately RPM=120 , this is not enough. When the crankshaft rotates slowly, there is some difference between the actual...
