A6 non start

Got a T reg A6 estate diesel the serpintine belt snapped,replaced it now car wont start there is no diagnostic codes anyone any ideas

What year is the car, is it an auto or a manual, and does it turn over (starter engages and spins) or does it do nothing? Did you disconnect the battery to perform the work? Give us some more details and maybe we can figure it out. Thanks, Paul

Its a manual engine spins over fine even checked to see if any belt debris had got its way into the timing belt ,never disconnected the battery just pulled what was left of the old belt off and replaced it with a new one . Its a 1996

Does that motor have camshaft sensors or a crank position sensor that might have gotten damaged when the belt flew?

Is it possible the fuel system lost prime? If there's a lot of air in the fuel lines, it will collect at the injectors and prevent them from pressurizing and the engine won't start at all. If you suspect this, crack the lines at the injectors and crank the engine that way until fuel starts to spray out. Stop, tighten, and crank.

Finally, why did the serpentine belt break? That is often indicative of another problem like a seized accessory. This could certainly prevent the car from starting. Will it start without the serpentine belt?
