• SES — P1415 Secondary Air Injection System Bank 1

1. SES — P1415 Secondary Air Injection System Bank 1
   

   So this light came on a few months ago…brought to BMW dealership and they replaced air pump and a couple other things, but the light came back on a couple days later (meanwhile the CPO warranty had run out.) So I scanned the thing myself and the error code is P1415. The gas mileage has also dropped from about 25 average to 21 according to the in dash gauge. The more I research this online the more confused I get, but my guess based on the information I have is a problem with the pre-cat O2 sensors.

   I brought the car to a non-BMW dealership and they scanned it and told me the MAF sensor needs replacing…however I know all they did was run a scan and the car has not had any performance issues… no stalling, rough idling, or anything like that. I also tried cleaning the MAF but the light still came back on after a few driving cycles.

   Thank you for any advice you might have!!

   Oh yeah, and I drive a 2003 z4 3.0i. I couldn’t find any guide to replacing the O2 sensor online for this car, but I found one for the e46…are they similar enough?

2. From my experiences with Benzes, anytime you get a fuel trim malfunction code its usually the MAF, and sometimes a secondary air injection code may lead to a MAF, but that is after a small bit of troubleshooting. Dirtracer will more than likely chime in, and he seems to understand some of these quirks rather well.

3. P1415 doesn’t have anything to do with the MAF, except possibly if the cause for that fault lies in the vacuum hose that operates the valve. in which case you could have an intake leak and thus a mixture upset.

   When the pump was replaced was the valve also replaced? A problem with the valve or a hose could result in a fault on only one bank. Another possibility is that the pre-cat O2 sensor on that bank is causing the fault. The pre-cat O2 sensors have a useful life of not more than 100k, so if that applies they need to be replaced whether or not they are a player in this fault (they may be a player in the reduced mileage).

   The car makes it possible, but the driver makes it happen.

4. +1. Check that vacuum hose to the valve, it lives just above the exhaust, and falls apart. But if you have a Secondary air code, your problem lies within that system, not at the MAF.
   Perhaps Jim will enlighten me how the O2 sensor sets a secondary air code, (but no mixture code) — not that I disbelieve you Jim — I just want to know how that works?

   ---

5. I could be completely wrong about this, but my theory is that this fault is set as a result of the DME not seeing excess oxygen in the exhaust when the SAS is running. The only way the DME could sense that would be via the pre-cat O2 sensors. A lazy pre-cat O2 sensor might not respond well enough to tell that sufficient air is being added to the bank it monitors.

6. Hmmm….. maybe, but since the SAS runs for 90 seconds at cold start, seems to me the O2 sensors might not even reach operating temp in that time.. But I don’t know for sure that’s true, since I have seen O2 sensors come on line in a minute or so. And since I’ve not been able to figure out how an SAS code can be given for a single bank, it seems likely that it must involve the O2 sensors; so your theory must have truth…..

   ---

7. That is the only way I can think of that you could have an SAS fault on a single bank. There are no sensors in the SAS system, so it seems to me that fault indication would have to come from O2 sensor data.

8. Hey guys, thanks for all the help. You’re apparently much better at this than my local shop. I guess I’m off to replace the O2 sensors…hope that’s the last I see of the SES light.

9. was this ever resolved? if so what was the issue? I have the same code and cant find the answer…. Thanks.

10. Same problem with O2 sensor and air injection P1415?
    

    My 2007 X3 (just under 50,000 miles) started off having big drop in gas mileage (25-26 down to 20 or less) and was throwing a code for the pre-heater on the bank 2 oxygen sensor. Took it to the dealer and they confirmed. Replaced the bank 2 O2 sensor. Then the car immediately started having idling problems, mileage was even worse, and now it is throwing code P1415. The short-term fuel trim at idle is quite high (29.7% on both banks) and the long-term fuel trim at idle is about 8% on bank 1 and about 15% on bank 2. Sounds like a very similar problem to what you guys have been describing. I also thought the old O2 sensor that came out of bank 2 was unusually sooty. Whaddaya think? I’m 300 miles from being out of warranty and the closest dealer is 300 miles away.

11. Having the same problem , anyone tell me what is the result??? Going crazy finding an answer

    ---

12. I am having the same problem. I have an 06 330i e90. My codes are p1415, p0174 and p0171. I have replaced all 4 o2 sensors and the MAF! Now what? Can anyone help me? I can’t even find the secondary air pump anywhere?

    Get it towed like 50 miles and drive the other 250. Lol

    Did you ever get this resolved? I’m getting these same 3 codes on my 2007 X3. The garage wants to replace the MAF.

15. I found this thread after changing the oil in my wife’s 07 X3 and immediately having a poor start / stumble and P1415 code. After a drive and inspecting for oil leaks as always, I found that the oil filler cap was slightly mis-aligned and not fully seated. Upon securing / re-seating cap I was able to clear the code and all was good.

    I share this to make everyone aware that codes can sometimes be indicators of very simple yet critical, small issues

    Had an issue with my wife’s car and this was the trick. Thank you for sharing.

17. Old thread, but helpful. Car started running rough this morning. Had the first frost last night, figured my car just didn�t like the cold. Got code p1415 on the way to work. After much internet research, found this thread. Checked the oil cap (opened it when I filled up last night) and it wasn�t seated right. Put it back on, car starts and runs great.

18. This is an old thread but still applies. My 07 Z4 3.0i was running rough at idle. Eventaully threw out p1415, p0171, and p0174 codes. This thread had the solution. Turns out I had had the oil changed but had not really driven more than a few miles then parked the car for a few weeks. Took it out yesterday and it gave the codes. Found this thread and the good old oil filler cap loose was the culprit. Good as new after tightening it and clearing codes. Thanks.

19. I had the car scanner code P1415 come up after adding oil into my 2008 BMW X3. My car was instantly running rough @ idle and at low rpms while driving. I thought Damn! Here we go again into the shop!$$$ But then after reading this BMW forum thread on the P1415 scanner code I saw that several people stated that this code was caused simply by the oil fill cap not being threaded on correctly causing some type of vacuum leak. So I thought Hmmmm! I just put oil into my motor and bam! this all happened to me! So I got off the computer went out to the garage loosened / took off the oil fill cap retighten the cap back on twice just to be sure it was on tight and correctly. Took the car out for several short test drives and BAM! immediately started to run better. And after driving the car for 3 short test drives shutting the motor off and then back on after each run…Bam! The «service engine soon» button / light on the dash TURNED OFF! (= the code P1415 disappeared! Man! Was I Happy! This BMW forum Kicks Butt! Peace!
