Hey Folks. 1998 A4 2.8L V6 has been running rough off/on for a little while. Codes always came up as "0" (normal funtion). Tonight the car really started running rough. New code popped up "15.7" which according to my chart means "Air Flow Flap, sporadic block".

Anyone know:
1) Where it's located?
2) How hard to change?
3) How much it costs?

Thanks for the help.

 

"15.7" is not a fault code. Try again!

 

It's the code put out on the AC panel. "Code" is a relative term.

 

oh i c... Sounds like the flap inside the airbox. Take it appart and check it unless someone else has a better idea?
Acutally... Id take it in for an ecu scan. Autozone will do it for free normaly.

 

Good to know. Appreciate it.
How long does that scan take?

 

about 30 seconds. write down the fault code(s) and let us know whats up.

 

autozone is amazing... the second i ever get a CEL i take my baby straight to autozone and in 30 seconds i know whats wrong. Get in the zone, AUTOZONE... and check out whats going on

 

or you could get a vag and not have to go to autozone ever again

 

hmmm so its the blender flap in the aircon your talking about since your quoting A/C codes and your using the A/C to read the codes?? if so you need to use a proper diagnostic tool in the DLC to get engine codes
