Plugged in a durametric to check my fans were kicking in properly after I found a stone jammed.

It's identified a fault code on my car (C2S) which I need to understand.

P1682 - Secondary air valve final stage

Any idea where I can look this up or what might be the trouble if any - No problem with the car that I am aware of.

 

Anyone has info on this? I can't even find the part on the PET.

Thanks.

 

Using the search function I found this: https://rennlist.com/forums/997-gt2-...sb-re-rms.html go to post #7.

 

FWIW:

P1682
Electric exhaust flap

NOTE
Only for Carrera S increased performance (X51).
Short circuit to B+/ground or open circuit in the control line

Diagnostic conditions
---Power supply voltage > 7 V
---Engine running
---Switch exhaust flap on and off with button

Possible fault causes
---Open circuit of power supply to exhaust flap solenoid valve
---Exhaust flap solenoid valve faulty
---DME control module faulty

 

Thanks, but I saw that and unfortunately my car is just a regular 2007 C4S without X51 package, no PSE.

I could definitely can hear a clicking sound by the alternator (much like a switch doing intermittent on/off cycles). Additionally, the noise goes away AS SOON as the RPM rises above idle. Lastly, the noise is intermittent, and comes on as soon as the car warms up.

So far, we think it is part #2 on the diagram below.

 

Would you mind letting me know where your error code description came from? My Durametric shows as:

P1682
Secondary-air valve final stage.

thx.

 

i have a pdf with (most) all the porsche 997.1 DME codes. i got the download link from somewhere on here a while ago along with a workshop manual and wiring diagram. i think renntech may also have a listing.
