Hi guys,
Can someone please interpret the following diagnostics faults for me
18043 - missing message from A/C control sporadic
17740 - sensor for NOX - G295 signal too large
17478 - NOX sensor heating contral signal
17446 - Heating activation sensor for NOX open
Does my NOX sensor need changing? or is it something to do with the AC/heating? I have read some old threads about NOX sensors, but I am still in the dark. I do not want to take the car to Audi until I have exhausted other cheaper avenues. The other big question is....................will it be costly? would appreciate any constructive input.
