Mine keeps throwing fault codes at me,03778/10 and 03779/10. When these come up its always when im in the final stages of braking and it also de-rates for a few seconds. Sick of reporting it to Man service when it goes in to be honest.
Hi mate, my 05 plate TGA 430 started throwing these codes up. Turns out 3 injectors were blocked - Have a look inside your fuel tank. Mine had black gunge in it which was blocking the filters and injectors and fuel lines. All cleaned out now and it noticeably pulls better and fuel consumption has gone down by about 1 mpg. Been told it is the bio-diesel in normal fuel that causes the black gunge.
Although the sister truck to this one seems ok, there is the sludge inside the tank so i’m getting this one cleaned out as well.
Cheers.
