Sup guys.

Anyone run into this error code yet? Had my car mapped (A5 3.0tdi) and had this code pending ever since. It clears but when re-scanning it runs to 38% and then brings this error up again…its a ECM/PCM coms error but the car runs fine and nothing comes up on display leading me to think its the dongle that somehow has a issue communicating with the ECU seeing that it only runs to 38%.

Any ideas?

This error may occur due to the influence of the adapter on the exchange bus
Failure on the bus – there is no communication with the engine block

Is there any way around this? All sensors are displaying fine..its just that it wont pick up codes now with this comms issue..that is if the dongle is the culprit and its not a real ECM/PCM issue. Just weird that this issue came up after the remap.
