P0411 Audi -

Question

are this codes expensive to repair on 2000 adui codes r po1136, po118, and po411

Answer 1

P1136 Cooling fan control circuit malfunction

P0118 Engine coolant temperature circuit high input

P0411 Secondary air injection system incorrect flow detected

This can get expensive with the engine temperture having a circuit high input the ECM does not know the temperature of the engine condition this can result in a overheated engine condition especially if the cooling fan can not turn on. As for the secondary air injection hose you can be just a pop out air injection hose and a simple reinstall of the hose.Hvae the cooling system repair first which is the most important.
