Ошибка 29F5 у автомобиля BMW была обновлена 12:34. Определить ошибку в автомобиле BMW можно через диагностический прибор через соединение OBD2. Если у вас определена ошибка под номером 29F5 — тогда прочитайте ее обозначение согласно официальным техническим регламентам автомобиля BMW.
29F5
Засорение катализатора, которое может быть связано со следующими проблемами:
- регулярное использование низкокачественного горючего;
- естественный износ узла;
- засорение сотового фильтра.
Силовой агрегат при такой проблеме начинает работать нестабильно, возможно снижение мощности и отсутствие реакции на нажатие педали газа. На приборной панели появляется индикатор Check Engine, а также увеличивается расход потребляемого топлива.
Для проверки катализатора на предмет засорения можно прибегнуть к одному из следующих способов:
- Посветить на устройство с помощью фонарика. Лучше всего загнать автомобиль на яму и демонтировать узел.
- Попробовать определить засорение на нюх. Если катализаторное устройство забито, из выхлопной трубы будет выходить газ с едким запахом.
- Подставить к глушителю руку. Если узел работает нормально, пользователь почувствует серьезное противодействие. В случае, если катализатор забит, серьезного сопротивления не будет.

Ошибка по лямбде
Комрады, выскочила сегодня ошибка 0029F5 DME: нейтрализация CO2
Якобы одна из вторых лямбд… можно менять. а можно отключить вторые лямбды, выкинуть каты и прошить под Евро3. Обещает быть чуть порезвее… пробег за 200тыс км, поэтому каты ясно подз@ср@ны.
Вопрос: ваше мнение. стоит ли? Не пропадет ли тот самый «подпор» в выхлопной системе?
зы. В принципе, если и буду делать, то каты сохраню… и на край смогу сделать откат на Евро4.
зыы. или просто поменять лямбды?

Getting codes 29F4 29F5 — O2 or Cats?
Not sure if I should replace the cats or O2 sensors. I’m getting the SES light, but have some other Misc codes. Car seems less than quick off the line in normal driving. Car is new to me and was pretty poorly maintained. Only has 82k miles, but needed plugs and filters pretty bad when I got it. I just changed them, cleared all the codes, but these two codes keep coming back
Codes 29F4 and 29F5
What should I do first? O2 sensors? Which ones are more likely to need replacing? before or after cat?
2011 328i N52 auto
Thanks!
-
How many miles on your car? Catalysts have an 80,000 mile warranty.
That said, if the O2 sensors are reading incorrectly, OR if you have crankcase ventilation problems, or other issues which are causing the engine to run less than perfectly, that will certainly cause catalyst efficiency codes.
-
82k miles. If it was the O2 sensors, which ones would be most likely to fail? Pre or post cat?
thanks for the help.

Do not erase codes. Take the car to a dealership, and advise them you’ve been told that the catalytic convertors have failed, and ask them if they will replace these under federal emissions warranty. Do not clear the codes, and do not mention a forum.
Midland’s not that far away. (I lived in Terlingua for 12 years)
-
What maintenance have you done on the car? How old are the spark plugs? What repairs have you had to do?
-
I changed the the spark plugs, air filter, cabin air filter, less than 200 miles ago. Bought a scanner, cleared the codes, drove it. After about 45 mins of driving SES light came back on. I planned on changing the O2 sensors, but didn�t want to waste the money if I was going to have to replace the cats. Car drives fine, but like I said, a mild stumble from a stop.

Even if you end up having to replace the cats, it would be silly to put the old O2 sensors in the new exhaust. Cats don’t just «die». Something kills them, like an engine that’s running too rich or too lean, or dumping oil into the exhaust, etc. If the cats are dead, so are the sensors.
-
Sounds like you�re saying you think the cats are done, and I shouldn�t bother with changing the O2 sensors, right?

No, that’s exactly the opposite of what I said. Replace the sensors first, clear the codes, and see if they come back. If they do, you need cats also.
But know that the cats didn’t die because they were old. If they’re dead, something killed them and you need to fix that something before replacing the cats, or you’ll just kill the new ones.
You might also want to have the latest software loaded into your car’s computers, in case there’s an update relating to this.

Ok I understand. Should I replace all 4 sensors or are the 2 pre-cat sensors or the 2 post-cat sensors more likely to cause this problem?

Well, that’s a difficult question. The primary sensors certainly live in a more difficult environment…AND they contribute more to the fuel mixture decisions made by the computer. On the other hand, the secondary sensors are the ones which are sending the information that the catalysts are not doing their job, because they’re measuring the efficiency of the cats.
Personally, I think you’d be best served by having a little more hands-on professional diagnosis done by a BMW specialist shop. It’s not normal for a car to be having catalyst efficiency codes at this mileage. Perhaps the engine’s burning oil, or perhaps it’s running too rich or too lean (which should set other codes), or maybe BMW’s even got more recent software for your computers that will have a «fix» for this issue.
Your oxygen sensors are very expensive — the catalysts even more so. I have to again recommend proper diagnosis of causative faults BEFORE throwing parts at it.
-
O2 sensors and cats are probably quite OK, since both banks are reporting the error simultaneously.
I am having the same problem on an N52B25 in a 525xi (Europe model). So far, I have eliminated other error codes that might have been causing the cat errors, including Vanos solenoid exchange and both DISA valves renewed, new sparkplugs and airfilter.
Due to excessive oil consumption, I even had a major engine overhaul done with new piston rings and crankcase ventilation and a total overhaul of the cylinder head and valves. It seemed to cure the oil consumption but had nothing to do with the cat error codes.
“My” BMW expert mechanic has found the brake booster is leaking air. And that air — he explains — ends up in the intake via the crankcase ventilation. And the electronics cannot measure that air and thus it gives the wrong air / fuel mix, which in turn may be causing the cat error codes.
And he is right that it leaks air: For about 20 seconds after I stop the engine, I can hear a hissing sound and after that there is no pressure left to assist me in applying the brakes. And if I push the brake pedal while stopping the engine, the hissing sound is delayed until I release the brake. I.e. the valve in the brake booster closest to the brake pedal is leaking air.
I hope he is right about this vacuum leak causing the cat error codes. He also claims that failing cats on an N52 is not a common problem. But the error codes are. And they are usually caused by a fault in either the intake system or the fuel injection.
I have ordered a new brake booster.
JimmyJam83: What did you do to solve your problem?
-
Some body needs to do the correct diagnostics before changing any parts
-
New brake booster mounted. It made no change to the error codes. But the brake booster is now working as it should. So no money wasted, but still left with catalyzer errors.
Next up is examining the internals of the cats with a camera.
-
You rebuilt your engine because of excessive oil consumption. All that oil went through the cats, which is very likely to have ruined them. Oil, coolant, rich mixtures or lean mixtures will all destroy catalysts very quickly.
-
That is absolutely correct. The camera revealed ruined catalyzers. They have now been replaced and the error codes are gone. Or at least there are no error codes after 600 km.
I am just mad that when I bought the car, I asked BMW how much oil such and engine may consume. Their answer was one liter for every 1000 km. And at that time, the car “only” consumed a liter for every 3500 km. So I was left with no possibilities for complaining where I bought the car, even though I bought the thing with 3 months guarantee.
After a couple of years and 40.000 km more, the oil consumption had worsened and was a liter for every 1500 or 2000 km. I.e. never as bad as BMW’s “specification” for what makes a bad engine. But obviously more than enough to destroy the catalyzers.
-
If the cat codes are efficiency faults then cats are done or you install this spark plug adaptors on the o2 sensors to pull the sensor out of the exhaust stream and the faults might not return. Of course the cats would still be bad but the light would be off.

Hi all sorry to be a pain
I have a BMW 1 series 2009 116i which kept cutting out when driving happened once 6 month ago and then recently started again and jumping when driving. Long story short I took it to a garage who did a diagnosis and the codes were:2A26/Present — DME catalyst converter in stratified charge mode.
29F4/Not present — DME catalyst converter Conversion
23C1/Not present — Oxygen sensor emissions control.The garage said a new converter is needed which is fine … estimated a few hundred pounds. I decided to save some money and fix it myself(the garage arent very reliable and I can’t drive it far as its stuck on limp mode) however there are TWO catalyst converters on the car (manifold and the exhaust) the garage haven’t told me which.
I’ve search google/YouTube etc. Any ideas?
Currently have a manny cat on hold at a party dealer so I have to get sorted soon! Any help or ideas would be really appreciated!
Thanks in advance!!

Hey i have the exact codes well 2 of them 2a26 and 29f4… i have changed the o2 sensors but it didnt work.. did you fix your if so which catalytic converter was it the manifold or rear one and did it work after replacing ?

Всем привет!
Посоветуйте, как поступить с забитыми катализаторами на N52B30? Горит ошибка, забиты катализаторы. Кто сталкивался? Если снять выпускные коллектора и выбить катализаторы? Какие плюсы/минусы по мощности/расходу и т.д.? Потом необходимо прошить под безкатализаторную я так понимаю? Существует ли такая на 530XI (CU19393)? Что еще необходимо сделать что б забыть про катализаторы?
Заранее благодарю за любой толковый совет!
-
Выбивать их нафиг и ставить пламегасители…Все решаемо и с прошивками…..Ну или менять.Ценник не порадует.

Катализатор можно уморить не по пробегу, а заправляясь где попало… По сабжу, конечно выбить и решить вопрос с прошивкой или поставить прокладку под лямбду.

Пробег меньше. Про каты сообщили на станции после чтения ошибок. Ошибку стерли. Загорелась снова. Купил шнур. Установил инпу. Прочитал следующее:
29F4 Catalytic-converter conversion
29F5 Catalytic-converter conversion (bank2)Стер в воскресенье вечером. Катаюсь, пол дня не горит Ждемс…
Кто-нибудь может пояснить эти ошибки? Верно ли приговорили каты или проблема может быть в другом?

катализаторы не выполняют свою функцию. но это не значит что они забиты. достаточно перевести машину на евро2, и ничего не резать

Ошибка пока не горит…Уважаемый GUNhed, поясни пожалуйста — перевести машину на евро2 — это и есть так сказать безкатализаторная прошивка или это понижение требований к работе катализаторов? И если у меня каты не выполняют полностью своей функции или забиты, а я переведу машину на евро2, без каких-либо вмешательств в сам катализатор (не вырежу его), как это отразится на мощности мотора и расходе топлива?

На другом авто, мотор N54 записаны ошибки DME:
2C9C
2CAA
2CA6Вот как у меня получилось расшифровать ошибки:
2C9C Oxygen sensor heating before catalytic converter
2CAA Lambdaprobe before catalyst, temperature
2CA6 Oxygen sensor heating before catalytic converter, functionПосле того как стер ошибки, занова выскочила только 1 ошибка: 2С9С
Кто может пояснить эти ошибки и как определить на каком из катализаторов ругается лямбда? Как определить где bank 1, а где bank 2?
-
ОЙ 2С9С ЭТ ОШИБКА ОТСОХ НАГРЕВАТЕЛЬНЫЙ ЭЛЕМЕНТ КИСЛОРОДНОГО ДАТЧИКА ДО КАТИКА ПОНЯТНО ДАЛЕЕ БАНК 1 ЭТО РЯД ЦИЛИНДРОВ 1 2 3 БАНК 2 РЯД ЦИЛИНДРОВ 4 5 6
-
Спасибо за ответ! Т.е. проблема лечится заменой лямбды перед катом 1-3 цилиндров?
-
Можно ли из этих ошибок определить bank 1 это или bank 2?
С чего это я взял, что bank 1 Сам уже запутался… Поясните кто может.

Катализаторы могли ославиться , что привело к потере мощности. Вырезать поставить обманку и будет счастье.

Забились значит поменять надо
-
На 525 прошил безкатовую прошивку, каты не трогал, через неделю эксплуатации начало вонять паленным, надо обязательно вырезать каты если будешь переходить на евро 2
-
Спасибо за отзыв! Вот и я думаю, какой смысл в безкатализаторной прошивке без вырезания катов? Ведь они если мешают мотору работать, то будут мешать и при прошивке… А перепрошить просто ради лампочки чек энджин не серьезно))

Если каты не забиты — зачем лишняя работа. См.пост 10.

Codes 29F5, 29F4 I get fault codes 29F5, 29F4 every 500km after I delete them. What available actual values should I be looking for in the BT tool to torubleshoot the problem. What voltage or other values should i be looking for to see which O2 Sensor it is or even worse which Catalytic converter it is. Codes 29F5, 29F4 with Service Engine Soon light on. |

If i remember correctly bank 1 is the front 3 cylinders and bank 2 is the rear 3 so this would imply that both something is not working correctly in both exhaust pipes/both cats/both O2 sensors. Check the rear O2 sensors for both pipes as these are the ones that measure emissions. mithiral67 will always have these codes because he has no cats… Does the vehicle have a completely stock exhaust system? And what do you mean when you say brand new cats? As in the car is brand new, or it has had cats replaced? __________________ -2006 325xi — DD — 75 shot nitrous |

I don’t know how BMW warranty works but I am the second owner and the car was bought from insurance auction so I am assuming that there is no warranty. That’s why it hard for me to believe that the cats are bad. I know i can fix this problem myself with some help from the users on this forum. |

I changed the post-cat O2 Sensors. I reset the light. Drove 120km. Stopped filled the tank then drove another 5km then the light turned on. Could this error be caused the Activated carbon filter which filters the gas tank vent. It’s the oldest part of the car. I installed a used on because the original was damaged when I bought the car. The error doesn’t suggest that it has anything to do with it. |

I would check with BMW first just to be sure its still under warranty and ask the dealer to work on it. Insurance auction or not, i’m pretty sure its still covered. |

Maybe the cats are clogged? Floor it a few times to get clean then out. If a bunch of black smoke flys out of the exhaust then you have some carbon buildup in the exhaust. __________________ —Marcelo |

I get these codes on my e89 N54 Z4 35i. Codes 29F4 29F5. I have not seen a warning light on the dash/idrive and when I check the idrive it says no faults. Car drives fantastic. I believe it could be caused by BAD FUEL since both cats give the fault code. BTW my car is brand new — only 3500km done — so chance for BOTH cats to have gone bad at the exact same time is very slim. |

I get the same codes on my e89 35i z4, I think it might be the E85 mix I am running. __________________ 2015 F80 M3 DCT : JB4 : Gintani DP : METH : BMS INTAKES : Upgraded Turbos : GTS DCT Flash |

These codes appear with no aftermarket hardware (ie downpipes). I noticed they happen only on certain brands of fuel. BP seems to be the best so far for not triggering the codes. Again no loss of performance/idle/odd smells etc noticed. |

Anyone know the exact cause of these codes for cars without catless dp’s or exhaust mods (ie stock)? |
