Bought a BMW 320i 2010 for dad from Evans halshaw about 2 months ago and the car's gone into limp mode. I've cleared the codes but they've come up again:
30DA - NOX sensor signal
2AEC - NOX sensor diagnosis
2AF9 - NOX sensor NOX signal coast mode check
2AA1 - Camshaft Sensor, outlet signal
2A99 - Crankshaft Outlet Camshaft, Correlation
As it was the standard free 3 month warranty we didn't get any paper work regarding exclusions. Is the NOX sensor usually covered by warranty? Also any ideas on the 2AA1 and 2A99 codes? The main issue is that Evans have told me that they will charge £50 diagnostic fee if it isn't covered by warranty
