Product Information

This is a diagnostic loom for temporary use with the Webasto Thermo Top C fuel burning heaters (FBH) as fitted to Volkswagen, Audi and other VAG group vehicles which use PIN 1 for the diagnostic connection.

ONLY for Volkswagen/Audi Thermo Top C heaters, click here for the version for other heaters.

Allows fault finding and component test using the Webasto Thermo Test software. See www.disco3.co.uk/fbh for more.

The loom connects to the vehicle battery or a 12V power source (e.g. underbonnet 12V point) with crocodile clips, and to the FBH with an 6 pin plug.

The connection for the OBD adapter included as standard (see below) is provided by an OBD socket, no fiddling with getting pins in the right place on the adapter's plug!

Instructions for fitting the loom are available to download from here: link (PDF) - this is for the TTV fitted to a Discovery 3 but the principle is the same for all heaters.

Instructions/manual for the Webasto software is available in the wiki: click here

IMPORTANTthis kit now by default includes a USB to OBD2 adapter for K-line communications, fully tested and working with the Webasto software. If you have an adapter already it can be deselected.

Made by us in the United Kingdom.
