12.2.5. MSR. The system preventing blocking of driving wheels


The MSR system is established on cars with diesel TDI engines and prevents blocking of driving wheels on the slippery road if the driver sharply releases an accelerator pedal. In this case the ABS sensor sends a signal to the control unit the engine and it quickly increases engine turns therefore wheels start to rotate without blocking and the car remains normally operated.

In the presence of malfunction the system of electronic control is automatically disconnected, thus on a combination of devices lights up control lamps. In this case the brake system works in a usual mode.

If during movement control lamps of ABS and EBV light up, keep in mind that at sharp braking there can be a blocking of back wheels.

Fire of one or several control bulbs during movement signals about system shutdown. Thus it is necessary to execute the following actions.

1. Stop the car, switch off and start the engine.
2. Check tension of the accumulator. If it is lower 10,5 In, charge the accumulator.


If the control lamp of ABS burns at the beginning of a trip, and then dies away, it testifies that tension was an admissible limit for ABS work, but then raised as a result of operation of the generator.

3. Check a condition of plugs of the accumulator.
4. Lift the car, remove wheels and check serviceability of electroconducting of sensors of speed of rotation of wheels.
5. If malfunction is not eliminated, further check is necessary for making at service station.
