Just replaced the evap N80 but still get incorrevt flow. Does this mean the purge valve is crap or there another leak somewhere. It passes the leak test but fails and says evap is not ok

We need more information. Please post the complete Auto-Scan. If you are using VCDS-Lite the button will be labeled [Copy Results] rather than [Copy] in that video.

You already had a Auto-scan posted!

Did you ever check this (below) from your other post (btw, I would not start multiple threads , for obvious reasons, for the same vehicle concerns). Members and RT employees , post #2, are joining in repeating all the same questions.

Much better. That one is readable.

If it were mine, I think the first thing I would try is pulling the oxygen sensors and swapping them from Bank 1 and Bank 2. Give them a cleaning while they're out. The ECU will flag CAT efficiency based on oxygen sensor behavior and it's not unheard of for an old sensor to be just lame enough to cause such a fault without the ECU flagging the sensor as bad.

While you have the sensors out, you might want to stick a borescope camera in there and visually inspect the CATs for obvious damage. If the matrix is has visible damage, then it's probably replacement time. At 130,000 miles it's not inconceivable to have a bad CAT, especially if the engine has had misfire issues at some point during its life.

Problem is OEM CATs are expensive, and aftermarket ones generally don't work well enough for the ECU to be happy with them for very long.

-Uwe-

Yea trying just see where these sensors are is a nightmare let alone trying to attempt to get them out. Obviously designed so you cant do it yourself and have to take it to a stealer. What a joke.


Yes, you bet, this can be challenging work! If you are not comfortable with it or do not have the necessary tool collection, you may have to take it to a private shop or dealer.

Ultimately, you are going to have to do some disassembly and testing and then let the forum know what you find.
