π§ π 2014 Audi S7 with some random fault in quite a few modules. After some oscilloscope diagnostic this one was another CAN bus issue.
Sometimes the module is the issue. This car had a module putting noise in the bus, Gateway has a fault for no comms to the j527 but module is accessible via DLC.
Narrowed this guy down to a failing CAN transceiver in a module. First two pictures are with the bad module plugged in, last two are bad module unplugged. This scope is a huge help with this, loving this thing.
Weβll get this replaced and programed then back on the road. π π¨
Audi, Volkswagen, Porsche, if itβs VAG we got you! Give us a call.
