The clock pulses for the turn signal and hazard warning lights are generated by a relay in the relay box, a so-called flasher unit. The turn signal and hazard warning systems are protected by separate fuses in the fuse box.

  • If the turn signal flashing rate is faster on one side than on the other, a bulb on the "faster" side is defective or there is an open circuit.

  • If the turn signal and hazard warning systems fail, first check fuses 1 and 17, see page 248.

  • For all other faults, the flasher relay is usually the cause. The flasher relay is located behind the lower steering column cover, on the turn signal switch. Terminal assignment on the flasher unit; the connector tabs are marked:

  • Terminal 31 is ground (negative, as is general in vehicle electrics)

  • Terminal 49 is the relay input (positive is constantly applied), terminal 49a is the relay output

  • An additional wire goes to the indicator lamp in the instrument cluster. With a towing device, a further wire may be present for the trailer turn signal indicator.

  • If no new relay is available, carefully insert a thin wire between terminals 49 and 49a in the relay connector. Caution: the sensitive relay contacts must not be damaged. Bend the wire ends before inserting them so that there are no sharp edges. Refit the defective flasher relay.

    The connector tabs are long enough that the relay can be plugged back in despite the bridge.

  • Switch on the ignition. If the turn signal lever is now operated, the corresponding turn signal side lights up continuously. Switching on and off with the turn signal lever can produce a flashing rhythm.

  • If the turn signal light does not come on even with the relay contacts bridged, there is a fault in the turn signal switch or in the electrical supply line.
