 Then the spacer and the cable are mounted. The spacer should already be mounted. Without it, unnecessary pressure is exerted on the circuit board and it can be damaged.

 Despite careful work during the installation of the tacho board, it can still happen that not everything works.

+==== Error: Strange behaviour of the speedometer light and the displays when switching on the light. ====
 Cause: There could be a defect in the electrical system. e.g. missing mass.

 Solution: Please check or have checked if all signals are correctly connected to the connector for the instrument cluster. Above all, the ground must be applied correctly.

+==== Error: The oil pressure control does not work. ====
 The cause could be an incorrectly adjusted oil pressure control.

 Solution: Check that the oil pressure control is set correctly. If you don’t have dynamic oil pressure control, then the switch must be set accordingly.
-=== Error: The LEDs do not work partially or not at all. ===

 Solution: VW has installed various series resistors for the excitation current of the alternator throughout the entire construction period. This may cause the behavior to change with the new board.
@@ Line 271: / Line 273: @@
 Since this is not a fault and does not affect the function of the alternator, there is no need to change anything here.

+==== Error: I got LEDs for the speedometer light and they don’t work. ====
 Cause: LEDs have a polarity. If this is not correct, then they do not shine.

+==== Error: I retrofitted a DZM and it doesn’t work or is wrong. ====
 Cause: Although you can also retrofit a DZM wonderfully with the kit. But unfortunately you can’t just take any DZM. Since the board does not modify the signal, the DZM must already be suitable for the engine.
@@ Line 283: / Line 285: @@
 Solution: Check if the DZM is the right one and if it is OK.
