EVAP capillary leak (0.5mm) detected

Guys,

This problem been bothering lately.

The check engine light does not come on. I can only pick it up when scanning with my Peake's Tool.


I already changed my fuel filter, fuel pressure regulator, and the fuel hose around the fuel filter/fuel pressure regulator.

Additionally, I also changed my gas cap.

No matter what I do I keep on getting this error code. I know .5mm isn;t much but now it is driving me crazy.

Prior to the problem, each time I open the gas cap fill my car at the gas station I will always here a "gushing/vacum/pressure" sound. However, ever since I have the "EVAP capillary leak (0.5mm) detected" error I no longer hear that "gushing/vacum/pressure" sound from my gas tank.

Any ideas?

I am having the same error (also with the Peake tool). But I also have the error 41 (Camshaft sensor - intake cam).

Could you figure out what is wrong??

I had this same prob in summer, and dealer replaced the evap canister valve in rear that syphons fuel between the tanks.. apparently it's common to replace these once in a E46 lifespan..

Maybe this is why.

Prior to this problem: My gas tank would always have the glushing sound (ie...opening a soda bottle) when I am at the gas station filling my car up

After the problem: No matter how low my gas level is I will never hear the gushing sound.

My dealers thought my gas cap was not tighten. That was false. I got so upset that I replaced my gas cap with a brand new one. However, that didn't fix the problem either.

I will tell my dealer evap cansister valve thingy though. Thanks!!!

I second that. I'm pulling two code, both referring to the air pump.

I'd like to see what the service sheet said.

Check the solenoid valve that is on the passenger side rear of the car, on the underneath, behind a black plastic cover. Remove the plastic cover and then unhook the little solenoid (looks like an inductor coil of copper wire with a valve on the other side -- about 1 1/2" long and as big as a quarter around) and then pop the cover off the solenoid, re-grease the rubber seals front and back, and put it back together. The rubber seals and the solenoid are made a lot better than they need to be so don't replace the part. Just refresh the seals with some fresh dilectric grease (which is merely a high quality vasoline grease).

The car does this evap test every other time you drive the car basically. It runs a small pump that pushes air through a .5mm orifice into the evaporative fuel system. It then measures the load the pump encounters and checks it to see if, once it reaches a peak, if it must keep pumping. This shows a leak.

The leak could be anywhere in the evap system, but I would check valves, hoses, and the canister itself.

Error code came back. The dealers order some part for the replacement. I can't remember what he said. However, when I get my car fix (later this week. thursday or Friday) I will post the total price, part number, item discription, and whether or not it is covered under CPO warranty.

P.S. Please remind me to update if I forget. Lots of people on e46 post questions to their problem but are too busy to post updates so that other members can learn from their experience.

Does anybody know the part number of this "evap canister" or another name used for it? Could not find it on realoem.com.
