P0440 and P2A1A

[Lambobimmer]

Anyone know what could be causing these codes?

I recently installed dp's and the BMW dp fix.

I also recently cleaned my intake valves and I thought that might have left something unpluged or have a pinched hose and I could not find anything.

Car drives great but these codes triggered the service engne light.

Any help would be appreciated.

looks like something related to your fuel tank, a quick search shows that 0440 is a evaporative emission code and 2a1a is a tank ventilation system code.

Check to see if your gas cap is on nice and tight.

P0440 - Tank safety valve malfunction.
P2A1A - Could not find that code. Are you sure its P2A1A?

just as a hint for you guys, try searching without the P in front of the codes when searching sites like bimmerpost and n54tech, you'll find a ton more info.

It appears that I might have pinched the hose shown in this picture when I put my intake manifold back on. What does this hose do and would it throw these codes?

P0440 is loose gas cap. It takes three or four trips after you tighten it before the indicator will clear.

What promoted you to take the heads off and clean the valves? How'd it look in there when you first took them off, bad?

I did not remove the head. I only removed the intake manifold, which is pretty easy. As you know these engines are known to deposit carbon on the intake valves and I wanted to check the condition. They were bad enough that I decided to clean them since I had everything apart.

Oh yeah, doh! My mistake. That's what happens when you take a quick glance from a mobile phone...

That's good, how do you drive it? How many miles are on the motor? Your making me think about doing this...

I have only owned it since December and it has 28k on it. I have had a Cobb tune on it since January. I have a 12 mile to commute to work and I usually get on it once or twice a day. I don't drive it really hard.

interested to see what lambo has to say. i recently had all 6 plug replaced because cylinder 5 was misfiring and the dealer found the other plugs a little fouled up. i'd guess it's due to carbon buildup

It seem as if the pinched hose was causing my problem. I unpinched the hose, cleared the codes and drove it around for 25 miles and no thrown codes. Hopefully it stays that way.
