How to Use Lonsdor K518 Pro with SVG149 Cable?

 Here is an example of how to use the Lonsdor K518 with the SPVG SVG149 NEC Dash Cable for a VAG VDO cluster with all keys lost.

 

Cluster type example: VDO NEC24C64

The SVG149 cable is designed to work for the ALL KEYS LOST solution on VAG instrument clusters with the NEC microprocessor. The SVG-149 cable allows you to plug your Supervag directly into the back of the VDO VDD cluster.

FYI:

The Pogo PIN method can corrupt eeprom checksum on VW Polo, Seat Ibiza and Skoda Fabia so better to avoid use this method on these. Generally speaking of course the best method is to read eeprom and modify it to enter service mode, then you have backup.
