I have a 04 DT 466 e engine . Driver had a engine warning light come on at times . Checked with Service max and got a 354 code . She said it didn't have any power . So my guess is we need a new turbo . I haven't checked the linkage yet . If the linkage is gone will it hurt to run the bus until a new turbo is installed ? After I shut bus off I went out a little later and code was gone and light was off . We really need this bus . Thanks for any help .
