Title:

EGR valve with a pneumatic cylinder control

Fault:

When an EGR valve receives a request to go to the closed position, the EGR valve position sensor T124 indicates an open position (> 8%) affecting engine performance (power and emissions).

The reasons:

  • The EGR valve could not close completely.
  • Spring return fault on the EGR valve control cylinder.
  • A problem with the operation of the valve block, V107.
  • The EGR Position Sensor T124 is faulty or disconnected from the circuit.

Notes:

After starting the engine, the engine control unit performs an active check on the EGR valve if the following conditions are met:

The engine runs at idle.

Engine temperature above 60 ° C.

There is no request to turn on the EGR system (0%).

Motor brake is not included.

EGR has been adapted.

The air pressure in the parking brake circuit is at a normal level (above 7.5 bar).

In the case of a DTC, the EGR system remains active and the engine power does not decrease.

A fault code can be cleared even if it is active.

Elimination:

Check:

  1. EGR valve control cylinder by activating the EGR valve using SDP3. Set the set point to 0% and make sure that the EGR position sensor T124 reports a position close to zero. If an EGR adaptation was performed, the position should be below 1%. If the position does not fall below 8%, a fault code is generated. If the position is close to 8% or above this value, this is the cause of the DTC.
  2. EGR valve control cylinder, connectors and wiring to EGR valve position sensor circuit T124.
  3. Functioning valve block V107.
  4. If the EGR valve position sensor T124 is faulty or disconnected from the circuit.
  5. After replacing the control cylinder, EGR valve, or T124 EGR valve position sensor, be sure to perform basic setup and adaptation of the EGR system using SDP3.

The reasons:

Jamming in the diffuser due to mechanical failure or due to insufficient pressure in the cavity of the executive cylinder. This can also be due to a blockage in the pressure relief valve channel in the valve block.

Notes:

The engine control unit shuts down the EGR system and calibrates the mass flow sensor.

If the diffuser remains in the closed position, then at high loads and high speeds, the resistance of the diffuser increases significantly. As a result, the boost pressure and engine power will decrease, and black smoke may appear in the exhaust gases.

Elimination:

  1. Check diffuser and actuator cylinder.
  2. Check the tightness of the on-off valve.
  3. Check for pressure relief through the valve block.

EGR composition

Fault:

Exhaust gas recirculated too little; It is not possible to increase the amount of recycled exhaust gas to a fixed level.

The reasons:

Possible causes of the DTC may be as follows:

  • The EGR valve shut-off element does not open. This can be caused by sticking of the valve itself, insufficient pressure of compressed air supplied to the executive cylinder or leakage of compressed air from the executive cylinder.
  • Track valve may be faulty.
  • The movable element of the diffuser stuck in the open position.
  • EGR gas leakage.
  • The mass flow sensor may indicate a too high value, as a result forcing the engine control unit to conclude that the engine is receiving too few EGR gases.

Notes:

The fault affects the emission of nitrogen oxides (NOx) by the car, and a warning lamp lights up in the instrument cluster, warning of a high level of pollutants. On vehicles with NOx control, a text message is also displayed.

Cars with NOx control

An active DTC cannot be deleted from the control unit. When the malfunction is resolved so that the malfunction code becomes inactive, the control unit must ensure that the malfunction has been eliminated.

Title:

System shutdown

Fault:

Incorrect procedure to turn off the engine control unit. Power line 30 was disconnected from the control unit earlier than line 15, that is, the power from the battery was interrupted before the ignition was turned off.

The reasons:

  • The power to the engine control unit was turned off prematurely.
  • This could be due to an incorrect engine stopping procedure with the ignition key or the engine being stopped using the ground switch.
  • The supply voltage can be interrupted if additional equipment is connected to the consumer.

Notes:

When checking in engine kill mode, the control unit performs a functional check of the components after the ignition is turned off.

If the car is equipped with the SCR system, then at a stop, the system hoses are cleaned. It is important that the SCR system can be stopped without interrupting the power supply. Otherwise, the SCR system may be damaged: the reducing agent in the hoses will freeze and the nozzles will be clogged.

With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed).

This fault also leads to a longer engine start.

It is assumed that the malfunction is resolved as soon as the engine control unit successfully completes a kill test.

An active DTC cannot be cleared until successful testing in the kill mode.

Elimination:

  1. Always turn off the engine with the ignition key.
  2. If the car has an SCR system, the main battery switch should not be turned off until at least 1.5 minutes have passed after turning off the key.
  3. Make sure that there is no additional equipment that interferes with the power supply.

Notes:

The mass flow sensor, oil pressure sensor and fuel temperature sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors.

A malfunction occurs because the mass flow sensor is not working. The engine will work with EGR, but without feedback on the signal of the mass flow sensor. Therefore, the control unit will only control the composition of EGR gases roughly, “roughly”, using predefined values ​​to set the position of the EGR valve.

Calibration of the mass flow sensor is turned off.

Malfunction affects vehicle emissions of nitrogen oxides (NOx); on the instrument cluster a warning lamp lights up, warning of a high level of pollutants. Vehicles with a NOx control system also display a text message.

Title:

Variable geometry turbocharger, mechanical failure

Fault:

The engine control unit has detected that the mechanism is not moving properly, with the result that the correct charge air pressure cannot be achieved.

The reasons:

Sticking of mechanical elements in a variable geometry turbocharger. This may be due, for example, to the presence of deposits, icing or damage to the guide vanes.

Notes:

The engine control unit turns off the EGR system and the engine power decreases.

The fault code cannot be cleared while the fault is present.

The time for confirming the DTC is 1 s, the time for invalidation is 1 s.

Elimination:

Check the mechanical components of the turbocharger by checking the state of the variable geometry turbocharger in SDP3. Mechanical damage can be detected already at room temperature. Jamming due to mechanical tolerances or deposits can be detected when the turbocharger has a high operating temperature. Therefore, it is also necessary to perform a check on a heated turbocharger. The heated turbocharger has a temperature above 300 ° C (the exhaust gas temperature in the turbocharger can reach 600 ° C). Measure the temperature of the turbine housing using a non-contact infrared thermometer.

If the result of the status check is unsatisfactory:

  1. Remove the actuator. Make sure that the lever with the toothed segment can move freely between its extreme positions when moved by hand.
  2. If the lever with the toothed segment can move freely: Replace the actuator. Reinstall the actuator using SDP3 and perform a turbocharger status check with variable geometry.
  3. If the reset or status check fails, replace the actuator.
  4. If the status check is successful, it is possible that the previous adaptation of the actuator was incorrect. No replacement is required.
  5. If the lever with the toothed segment cannot move freely: replace the turbocharger with a variable geometry.
  6. If the status check is successfully passed for both the warm-up and the cold turbocharger, the cause of the DTC is a temporary malfunction, for example, as a result of icing when starting in low temperature conditions.
  7. If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65.

Title:

Variable geometry turbocharger, danger of overspeeding

Fault:

Indication of exceeding the allowable rotational speed of a variable geometry turbocharger.

The reasons:

  • Excessive speeds could be caused by a combination of a number of factors: for example, the width of the annular gap in the nozzle of a turbocharger with variable geometry, the position of the EGR valve and the amount of fuel supplied. The annular gap of the nozzle and the EGR valve is likely to be fully or partially closed at the same time, since there is a high engine load at the time of the malfunction.
  • Turbine speed is measured by a turbine speed sensor. However, at the same time, the charge air pressure sensor checks the accuracy of the rotational speed. A fault code is generated if the difference between the actual and the estimated speed is too large. The fault may be present either in the turbine speed sensor or in the charge air pressure sensor.

Notes:

To reduce the turbine speed, the engine control unit immediately reduces engine power. Engine power will remain low until the turbine speed is sufficiently reduced.

The time for confirming the malfunction code is 30 s, the acknowledgment time is 5 s.

Elimination:

  1. Check the installation and operation of the turbine speed sensor T120.
  2. Measure the resistance at the turbocharger T120 speed sensor at room temperature. The resistance between pins 1 and 2 should be 850 ohms ± 50 ohms.
  3. Make sure the air filter is not blocked.
  4. Ensure that the charge air lines are not clogged and do not leak.
  5. Check the installation and operation of the charge air pressure sensor.
  6. Check if any other DTCs are generated. Take the necessary actions to eliminate the causes of other fault codes for the EGR system, fuel system or variable geometry turbocharger that were active.

Title:

Variable Geometry Turbocharger, timeout in the CAN bus

Fault:

The rupture of the communication circuit between the engine control unit and the turbocharger actuator with variable geometry. DTC, if not received a certain number of consecutive CAN messages.

The reasons:

Constant or repeated gap in the CAN circuits between the engine control unit and the actuator. Permanent faults are often caused by faults in the electrical wiring harness, connector or engine control unit. Repeated malfunctions are often caused by scratching the wires on the connector.

Notes:

The engine control unit turns off the EGR system and the engine power decreases.

The fault code cannot be cleared while the fault is present.

The time for confirming the DTC is 0.005 s, the time for acknowledgment is 0.005 s.

Elimination:

Check whether DTC 1686 has also been generated. If so, run diagnostics for this DTC. If not, see instructions below.

  1. Ensure that the connector on the actuator harness is healthy and clean and that there is no moisture in it. Replace the connector if it is damaged.
  2. Disconnect the connector between the actuator and the engine wiring harness.
  3. Measure the resistance between pin 3 and pin 4 in the actuator connector at room temperature. Resistance should be either 120 ohms ± 10 ohms or 2,600 ohms ± 50 ohms. If the resistance does not match the specified values, replace the actuator.
  4. Measure the resistance between pin 3 and pin 4 in the engine wiring harness connector at room temperature. Resistance should be 120 ohms ± 10 ohms.

If the resistance does not match the stipulated values:

Disconnect the connector from the engine control unit. Measure the resistance in the cable harness between pin 3 and pin A4_6 at room temperature. Resistance should be 5 ohms ± 4 ohms. Repeat the measurement for pin 4 and pin A4_7. Measure between the individual wires of the wiring harness to eliminate any short circuit in the wiring harness. Measure the resistance between the A4_6 pin and A4_7 pin in the engine control unit at room temperature. Resistance should be 120 ohms ± 10 ohms.

If all of the above measurements gave the correct values, the waiting time on the CAN bus is probably due to friction between the pin and the cylindrical contact in the connector. This type of rubbing is difficult to detect without advanced electronic equipment. Replace the actuator and the connector and the opposite connector in the engine wiring harness. Securely fasten the wiring harness and its connectors.

If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65.
