B6 Fault codes, please help! P0345, P0346, P0365, P0011, P0014, P0021, P0300

2001 Audi A4 B6 3.0 petrol quattro.
For a while now my car has been misfiring, loss of power and stuttering...
A mechanic checked the timing and it was fine (done the timing belt only 2 years ago), I've replaced the coil packs and spark plugs but still getting these engine error codes.. 

Anyone know what the cause of all these codes? (P0345, P0346, P0365, P0011, P0014, P0021, P0300)

Thank you
