2004 Passat 1.8 turbo wagon
Had six codes pop up yesterday. With the check engine light.
16795 secondary air incorrect flow P0411
16955 brake switch P0571
18057 ABS message P1649
16683 turbo under boost P0299
17887 Brake boost vacuum P1479
17544 Fuel trim bank 1 P1136
Any ideas why these would all pop up.
