BMW 320D E91 2009 - Dash warning lights on #
Posted by Steve Pearman on April 17, 2016, 8:48 amEdited by board administrator April 20, 2016, 12:56 pm
Year of Manufacture *: 2009|
Engine Size and Code *: 2ltr/N47D20
( Optional) Fault Codes: 4932/3FF0
This vehicle came in to there garage with no faults all they had to do was replace the pollen filter and reset the dash inspection, they used there snappy diag kit which had just come back from repair, while carrying out the reset the dash lit up like a christmas tree and put fault codes in most modules, they have managed to clear everything using another diag kit apart from the engine ecu which now is complaining about the air system
4932=Air system,Air to egr mass flow,plausibility
3FF0=Air mass flow sensor
Looking at the mass air data on idle actual is 483.1mg/stroke and does rise when reved but the specified reads 1270.0mg/stroke and stays stuck on this figure?.
I'm thinking the engine ecu has now been affected by the snappy tool but can't be sure.
Any Help Appreciated.
