2011- 323i. The automatic transmission stopped working last night. I pulled up at a traffic light and when the light changed I tried to accelerate and the car would not move. Just before this happened I heard a pop and thought a tire had burst. The car will not go forward or reverse. Had to get the car towed. No warning lights or engine codes and the car was running fine up to the stop light. Any ideas of what the problem could be ?

[@Itsallaboutthebuild]

Oh man, sorry to hear. Maybe something happened with the torque converter? Maybe have a transmission shop take a look.

[@jamesweber4938]

@@Itsallaboutthebuild It was towed to a garage.

[@Triplaajat22]

Can you tell me where the sensor is located? I've been looking for two days and I haven't found it :(

[@Itsallaboutthebuild]

@@Triplaajat22 which sensor?

So I'm now subscribed. Thank you so so so so(and many more) much.

[@Itsallaboutthebuild]

Glad you enjoyed the content. We're having fun with the BMW now that it's working. We plan to continue releasing more BMW content 🙂

[@dhalsim-1]

Just curious, shouldn't the throttle body valve open a bit more than that when accelerating?

[@Itsallaboutthebuild]

Depends on how hard you push the throttle…

[@YootubeUK]

Nice and thorough vid! Just had my 328 go into limp mode and came across your video. My throttle body was sticking shut a bit ( the car doesn't get used much) so I think some cleaner and start there. I had both rubber boots between the mass airflow sensor and the body split too which won't have been helping!

[@Itsallaboutthebuild]

Thank you very much. Figured we go through all the things we checked before we found the culprit. Glad you found your issue 👍

[@YootubeUK]

@@Itsallaboutthebuild I'll let you know but I'll definitely keep your video as reference. Yours was a nice methodical piece where most people would just start throwing new parts at faults.

[@Itsallaboutthebuild]

@@YootubeUK much appreciated. BMW parts are expensive. We can’t afford to just replace parts that aren’t bad 🤣🤣🤣

​@@Itsallaboutthebuild Even being in Europe when you need to buy genuine, ouch! A liberal squirt of my throttle body butterfly with some carb/erg cleaner this afternoon has made a lot of difference actually! It binding when fully closed after being snapped closed by the spring.

Does it matter which pin u connect the alligator clamps? Is there specific side for negative or positive?

[@Itsallaboutthebuild]

If you’re testing voltage with a multi-meter then it will show negative value if they are switched.

[@lucindajohnson4471]

I need one the reference books. For 03 z4 3.0.. where could I get that plz?

[@Itsallaboutthebuild]

From what I understand Bentley didn’t release a BMW z4 manual. You may have to search for the Haynes Manual for BMW z4 instead 👍

[@gamestompper03]

I haven’t checked but would it still be the pressure, if it acts like it’s pouring gas out faster than I put it in, won’t shift 5-1 won’t drive unless I gas it and aid i floor it the don’t even act like I’m flooring it

[@Itsallaboutthebuild]

Oh wow. Not sure if that’s the fuel pressure. Might be or maybe the fuel pump or fuel filter???

[@ImSlySnipes]

My BMW 2005 325xi has code P1635 and code p0341 and it’s been put into limp mode with the fault codes and I’m not sure on how to fix the p1635 code

[@Itsallaboutthebuild]

Strange. Not sure what could be wrong if you checked the same stuff so showed in the video. Only thing I can suggest is to check all systems related to P1635 and P0341. I’d look for ways to test components one at a time instead of just replacing parts that may not be bad. Falling into that trap will set you back loads of $$$ and possible still not fix the root cause.

[@gtagamer799]

Hello i have bmw e46 with eml light problem but the eml and check engine light pops up when engine get working temperature cold engine runs fine without any lights. If you turn off car and turn it again rev it it just go to the limp mode again imediatly.

[@Itsallaboutthebuild]

Take it over to any auto parts store and ask if they can scan for codes. Once you have some more engine codes, that might clue you into what to look at next 👍 How long has the problem been happening???

[@Somebody-ln1ni]

does anyone have idea what could it be with my car it its in limp mode for months, pre supply fuel pressure low (changed pumps) and last week well it cracks but wont start only with starter spray then drives (in limp mode) BMW E39 525d M57 engine

[@Itsallaboutthebuild]

Check for codes to help narrow down what to check

[@-zargati-]

Im experiencing limp mode as well, but the codes im getting are P0171, P0174, and P0305… lean codes and misfire on cyl 5… wondering if new pre-cat O2 sensor and new MAF will fix it.. any input??

[@Itsallaboutthebuild]

Misfire on cly 5…maybe check the basics of ignition system related to cly 5. Cly 5 spark plug, spark plug wire, ignition coil stuff….The best advice I can give is test each component instead of replacing parts. If you can find the bad part, you’ll save tons of money.

[@-zargati-]

@@Itsallaboutthebuild i changed all spark plugs and all ignition coils as they were pretty shot, i also did valve cover and VCG, since both were cracked… still no fix :( i will test them again though, i appreciate the response🤝

[@Itsallaboutthebuild]

@@-zargati- no problem. Hope it’s not something really bad. You could do compression test to see if cly 5 has something wrong with it too.

[@-zargati-]

Check all your vacuum hoses first 👍

[@iniixi-562]

@@Itsallaboutthebuild that’s exactly what I thought as well

[@Itsallaboutthebuild]

@@iniixi-562 if you had engine/transmission replaced it’s very likely that something could be missing or maybe you have a vacuum leak somewhere. After that check DME codes and test each component before you replace it 👍

@@Itsallaboutthebuild the code popping up is P1611 and I can’t figure it out. I changed the module and still nothing and the air bag light is on as well. I seriously need help

[@Itsallaboutthebuild]

@@iniixi-562 if you look up p1611 it mostly has to do with transmission computer not able to communicate with engine computer. If you had both engine/trans swap it’s possible that the transmission computer and engine computer are not matching up. Research if a shop can get this right for you, I’m not sure how to fix that type of issue…

Dang, were all the items we went through in the video good for you?

[@DonovanWalker-xd3ul]

oh the hunt for the source is actually just begun. I cleaned the maf sensor and no luck. but it's running lean codes for both banks so I have a feeling I need to replace the maf and then do a smoke test to diagnose where and how many leaks are in the hoses ​@@Itsallaboutthebuild

@@DonovanWalker-xd3ul good plan

[@ZIEVAX]

I have a 99 328i and it only goes into limp mode when I put the pedal all the down but once it's into limp mode I have to constantly turn it on and off until it goes away and my check engine light will go completely off and it drives fine certain times. The only thing I could think it could be is battery is done and it can't pull enough power for car to maintain as I've recently got oil change and oil service reset as I thought it was that but nope. Any help is really appreciated 🙏

[@Itsallaboutthebuild]

If you think it may be the battery, you should be able to have an advance auto, auto zone, or oriellys do a battery test. They can also check to see if any engine codes are thrown. That will help troubleshoot the problem. 👍

[@Itsallaboutthebuild]

We didn’t have any transmission issues with our LIMP mode. If it’s going into LIMP mode due to possible transmission issue, that may be a much larger and more expensive job.

[@abeledwards9643]

I have a 2007 328i and all of a sudden the car would accelerate very slow and wouldn't past 4000 rpms, any idea on what this could be?

[@Itsallaboutthebuild]

Sounds like a form of limp mode. Get yourself an OBDII scanner or if you can make it to a parts store like advanced auto ask them to check what codes are being thrown. The code or codes can help narrow down the potential issue. Good luck

[@joneich1591]

Dsc?

[@Itsallaboutthebuild]

DSC is BMW's dynamic stability control. In the e46, this will actually decrease throttle when the ECU detects wheel slippage. You can read more about it here: www.bmwblog.com/2009/02/06/what-is-and-how-dsc-works/

[@joneich1591]

@@Itsallaboutthebuild I believe a 2005 bmw 325xi has this issue. It came to me in limp mode, 127k on it. Random missfires and lean condition. It was way over due for all the vacuum lines, coil packs, plugs, ccv, so I replaced it all. Runs great for about 15 minutes of driving, then shuts down into limp mode. Reset the light, runs great again, until you drive it. The traction control light is on. It must be this problem, because everything else is good? Any thoughts?

[@Itsallaboutthebuild]

@@joneich1591 I would check for what codes are being thrown with an OBD II scanner. This will help pinpoint if there’s a bad sensor causing the issue. I believe DSC pulls readings from a few sensors. When I’ve experienced DSC making adjustments, it doesn’t put the car into full limp mode, but only reduces throttle response while it detects wheel slippage. Also make sure all your vacuum lines are good.

[@joneich1591]

@@Itsallaboutthebuild replaced all the vacuum lines, along with intake manifold gaskets and ccv. It only happens when driving and above 2500 rmps. The light trips, and goes immediately into limp mode, no power at all. Reset the light, and idles perfect. The round light is on constantly. It must be the dsc causing this issue.

[@Itsallaboutthebuild]

@@joneich1591 Yeah, could be a sensor related to DSC. Maybe a bad wheel speed sensor or something else. 50sKid channel has some good content on what to check out with DSC related issues kzbin.info/www/bejne/eafch3ateKarZ7M. Hope you’re able to find what’s wrong 👍
