We also had the opportunity to fit Canbus compatible HIDs into a 2010 Porsche Caymann over the weekend. Will update with pics shortly.

It has taken us 3 long years to work out the Canbus systems on the newer Jap vehicles and also the BMW, Benz and Porsche. All thanks to Lombardi Bros in Bentley for allowing us to cooperate with them over the years, allowing us to rectify the faulty hid systems on their vehicles that came in for warranty and insurance claims.

The CAN Bus is an automotive bus developed by Robert Bosch, which has quickly gained acceptance into the automotive and aerospace industries. CAN is a serial bus protocol to connect individual systems and sensors as an alternative to conventional multi-wire looms. It allows automotive components to communicate on a single or dual-wire networked data bus up to 1Mbps.

Canbus hids on late model vehicles also incoperate the daytime driving lights as part of the complex Euro IV compliance system

In layman terms, car manufacturers are using a better communication system CANBUS to control the lighting on late model cars, which are also resistance sensitive.

In other words, if you use a cheap china made hid conversion system, the dash will immediately pull up a fault code to indicate resistance incompatability in the lighting system. The CANBUS system will then shut down the lighting system and in this case, you will se a flicker of the hid lights once and the hid lights will be permanently turned off afterwards.
