Hi, check engine light came on so had it checked out, garage replased MAF and reset light, a week or so later the check engine light came back on so i purchased my own check tool, codes it reads are:
A) 27 - EWS message.
B) A6 - safety controller has shut down MDK function
C) 73 - air mass sensor
Can anyone help me understand what the real problem might be? Everytime I take the car in it costs a fortune and then still has something wrong, seams like trial and error.
Thanks
