In the response the modules are indicated as either present or not. This includes all module installed and modules the gateway should be able to talk to if installed. When using VAG diagnostics a full list of possible modules is sent after the appropriate request. Its a bit complicated how the original diagnostics work vs ISO OBD diagnostics. Well there is for the VAG group diagnostics but I don’t think there is for regular OBD protocol. Note this is all based on self learning and hundreds of hours of analyzing data.
This originates from the main MIB control unit and the MIB acts as a gateway for them for them. New VW’s and Audi’s with MIB system also have an isolated CAN BUS between all infotainment items such as Control panel and screen.
Older VW’s may have a specific DASH CAN that comes from Radio to Cluster. Pink and green I think? For sure Pink is one colour. Newer Audi’s are plagued with FlexRay reducing how much you can even use the Macchina on.ĭiagnostic BUS (OBD Port) (can be Orange/Black or Orange/Red)ĭrive-train BUS (can be Orange/Black or Orange/Red)įlexRay… Can’t sniff those. Some steering modules use Dual can like drive-train and comfort, others may use dashboard instead of comfort, some only only have one which is normally comfort… Some cars use comfort BUS for camera some use Dashboard new Audi’s use extended. Most VW have a single CAN going to steering but newer higher models have dual, Like most Audi’s.Įquipment varies from car to car. They change a lot between the year and cars.
