Audi A4 documentation, fault in the secondary air system (Solution)

Author: Michael II

2.4L and 2.8L V6 engines.
Exhaust warning light is illuminated, secondary air system malfunction.

Cause:
The engine control unit's fault memory indicates an error code for the secondary air system on bank 1, specifically "faulty flow rate" or "insufficient flow."
The cause is a kinked vacuum hose on the combination valve for secondary air.


Solution:
Check all vacuum lines in the secondary air system for leaks and kinks.
If the vacuum hose on the combination valve for secondary air needs to be replaced, then it should be replaced. It should be extended by 20 mm.
Please provide the German text you would like me to translate.
Bye.
