2003 A6 V6 - fault code P0441 / 16825 - purge valve replace (pics)
 

2003 A6 V6 automatic (no turbo, no quattro)
71,700 miles

Check engine light on.
Car runs and drives o.k. and fuel consumption normal.
The only things which does not look normal are:
- idling about 50 RPM higher
- when coming to stop, still in drive, RPMs go down a little and then idling about 50 RPM higher then normal.

Checking with ross-tech cable and software shows:
16825 - EVAP emission control sys
P0441-002 - incorrect flow - intermittent - MIL ON

I purchased purge valve from Auto Parts Warehouse for $60; part was aftermarket replacement, identical with OE, made in East Europe.

Engine Light after refueling. Any Idea's?
 

Thanks for the in site. I have a 2006 A8L 4.2 that gives me an Engine Light every time I refuel.
The purge valve has been replaced by the previous owner, so I was told.

Check engine light remains on or is off after a while ?
If it stays on, you have to check the fault code to be able to try to track what it is wrong.
Some Auto Zone shops do this for free.

Thanks, I am waiting for my VAG diagnostics to arrive to do just that. The light stays on. I have had my mechanic reset it once. That is when I found out what was causing the engine light. I may have a leak. Thanks again.
