Protocol Support for early VW T5

Post by basrad »

Hello again - after 6 months I have still not managed to get my Freematics OBD-II UART Adapter to work with my Van.

It's an early 2005 VW Transporter (T5) 2.5 Tdi

The adapter works fine with our other VW's (EOS and Golf) and I have made some working circuits to display data.

I was wondering if the creators of the Freematic devices can confirm that the 2005 to 2006 model VW T5's used a VW modified KWP protocol?

I read on the T5 Forum "there were two protocol being used by VAG KWP1281 (earlier) & KWP2089 (later) which are both VAG proprietary variations of the ISO 14230/KWP2000 standard."

Is there a way to gain communications with these modified versions?
