So I pulled an 06 A6 pcm today.....It's a Siemens unit instead of a Bosch....I imagine this is what you were referring to? Also found it interesting that the pcm connectors had a bracket of the connectors with tamper resistant bolts!!!!!
That's certainly a first for me! You guys must have really made them mad....lol. I acquired both the PCM and the connectors for "investigative purposes"
The Rabbit is just a Bosch 7.1.1 box.
