If complaints are made about the difficulties of sporadic failures in the comfort systems of the above-mentioned vehicles, the possible source of the trouble could be the ignition switch. A good description of such shortcomings would be "car electronics gone mad".
This can manifest itself in the following ways:
- The switching off of the radio or of the telephone function although the key is still left in the ignition.
- Sometimes the menu item "Telephone" can no longer be selected when the engine is running.
- The central locking system partly locks or unlocks erratically while the vehicle is being driven.
The following fault codes can be stored in the fault code memory of the vehicle electric system - comfort system:
- 00576, "Same as terminal 15 – electrical fault in the circuit, sporadic".
- 00883, "Same as ignition switch -D (Terminal S), electrical fault in the circuit, sporadic".
- 00884, "Same as ignition switch-D (Terminal X and P), electrical fault in the circuit, sporadic".
- 01744, "Same as ignition switch-D (Terminal P), electrical fault in the circuit, sporadic".
In order to find a solution to the problem, first of all a check on the fuses and the power supply of the systems affected should be carried out.
If no negative results are found here, this suggests that an ignition switch is defective. As a result of wear and tear in the switch, the clicking into position of the switch settings is no longer accurate so that overlapping can occur between the P and S contacts.
If this is the case, then the ignition switch has to be replaced. In the meantime, the original VW spare part has been modified.
