Hi all

Sprinter randomly smokes white now with no fault codes after dpf removed and programmed. However I noticed that there was a mercedes dealer device fitted to the obd port of the van orginally. Can anyone shed some light on why it was there and its putpose as the van has a regen function on its ecu anyway!!

Cant upload pic as files too large but it has diagnosebox written on it with a mer part number which makes no sense a906 906 00 37 0002


And the front has a light display and just says regeneration particle filter
