    Hello to all I was replacing timing belt on my A3 2012 and the car is not starting the car was running perfect with the old belt .

    I use all the correct tools and I believe that i did the all procedure correct, turn by hand like 5 times the engine and rotate fine.
    I have some picture of a hole that I drill to make my life easier to remove one of the bolts on the engine mount, the mk5 have this factory hole but the Audi A3 is like the mk4 with ALH engine to remove that bolt is a big problem.

    For the replacement I disconnect the fuel lines from the fuel filter not fron the quick disconnect, I cycle the system 2 times using the vag com and it looks like the air is on the system because at the pump near the filter sound like with some air are, how may time should I cycle the system or theirs another way to bleed the system

    I haven't put the antifreeze so the cooling system is empty and I have the accessory belt disconnected I don't know if this will prevent the engine to start?

    I put the computer and but the only code was immobilizer code but I an using the same key so at this point he car crank fine but it wont start and low oil pressure after crank the engine for extended time.

    Any idea it will be very appreciated

    thanks in advance

    I would guess at CFFA or CFFB.

    If it ran ok before you changed the timing belt then check all settings. Your model:

    A3 2.0D TDI CR 2009-11
    Engine code: CFFA, CFFB

    Is covered in my TDI Timing Belts App

    So tell me, why did you disconnect the fuel lines to change the T/B? Completely unnecessary.

    Yes no need from now on but at that time since was my first timing belt on that engine I was looking form more room to work. But definitively is better not to disconnect the lines.
