Hi all,

My car threw a CEL a while back and I finally got around to pulling the codes. The car seems to run fine.

It's an S5 Turbo with the air pump and the AWS deleted.

These are the codes:

11 25 30 31 32 33 34 38 42

The CEL came on after i popped a hose coupling off because I hadn't tightened the clamp enough.

Any ideas?

11 - Intake Air Thermosensor (Engine) - Intake air fixed at 68F
25 - Solenoid, Pressure Regulator Control
30 - Solenoid, Split Air Valve
31 - Solenoid, Relief Valve
32 - Solenoid, Switch Valve
33 - Solenoid, Port Air Valve
34 - Solenoid, Bypass Air Control (BAC) Valve
38 - Solenoid, Accelerated Warm-up System (AWS)
42 - ???

Maybe i need to double check that last one..

 

i would check the air temp sensor on the engine, code 11 that is important. the other codes are the ones it'll throw when you remove the emissions equipment.

 

according to alldata for code 42

Malfunction Code No. 42 Duty Solenoid (Turbo Boost Pressure Control)

 

Thanks for your help, guys. Maybe the code 42 will clear if i get rid of the FCD
