Всем привет.
Имеется X3 в кузове F25 с мотором N55. Пробег 150.000 км.
Постоянно висят ошибки P112F (Давление во впускном коллекторе/угол открытия дроссельной заслонки — корреляция сигнала, высокий уровень) и 101F01 (Некорректное давление угла открытия дроссельной заслонки).Из проблем, которые есть:
— неустойчивый ХХ
— повышенный расход ( около 18 литров по городу и это в пенсионерском режиме)
— вялая динамика (8,5 сек до 100)
— если авто заглохнет на Автоматическом Старт/Стопе, то завестись с него уже не может, приходится заводить повторно с кнопки.и самая главная — дергается/пинается на сверхмалых скоростях. Т.е при строгании или перед самой остановкой авто подгазовывает и получается пинок.
Что сделано.
— почищены клапана Тунапом
— почищены датчики MAP и MAF
— заменена клапанная крышка на новую оригинал
— проверено все дымогенератором — утечек нетЧто замечено.
На рабочем двигателе сначала отключаю Ванос, двигатель падает в аварию, затем отключаю разъем Вальвотроника и глушу авто. Подключаю Ванос, завожу авто и подключаю Вальвотроник.
После этих манипуляций горит только ошибка по Вальвотронику (135808) и авто начинает вести себя ИДЕАЛЬНО.
Холостой ход ровный, никаких пинков/рывков, турбина дует, авто едет, с авто старт/стопа заводится с полпинка. Но после того как заглушишь авто, все начинается заново.
При всем при этом никаких ошибок по Вальвотронику нет. Адаптацию проходит, углы запоминает, посторонних звуков нет. Когда снимали клапанную крышку обратили внимание, что снимались 2 и 3 свечные колодцы (может Вальвотроник меняли?)Еще. Давление во впускном коллекторе (на ХХ) при работающем Вальвотронике — 90 kPa, а при отключенном — 30-45 kPa.
Может кто то сталкивался с такой же проблемой? Как решили?
Как механически объясняется разница в давлении во впуске и идеальная работа двигателя при отключении Вальвотроника?
Спасибо!

само собой, при нерабочем ввт мотор работает в аварии.

Have had this code for quite some time; intermittent then not so intermittent, now permanent
Many things tried, swap out new throttle body, MAF, new plugs, a pair of matched sensors (which ones escape me at this point)Car now runs poorly at idle (occasional stalls), still ok at rpm though
Codes reveal the p112F always but now usually lists misfires as well.Garage is now telling me they feel there’s a timing issue that’ll be a $$ exploratory mission should I choose to pursue. Very conflicted on my next move.. any thoughts are welcome, but I feel better just writing this and expressing my frustration.

This code can be related to many different issues. Anything from an ECU adaption to a cracked cylinder head.
When I had the code, the dealer replaced my whole intake system. It went away for a bit, but then showed up again.
For what its worth, look for my «N55 adaption» thread and see if that works

Couple things can cause this one, the start of the death of a high pressure fuel pump. Try this first unplug the tank vent valve and let the vehicle idle for 15 mins and plug it back and clear the faults. This will reset the DME adaptations and if the fault stays away its fixed. If it returns the high pressure fuel pump might be the issue and need to be looked into.

101F01 — Throttle angle — absolute pressure suction, comparison pressure too high. I can’t seem to figure out what is causing this code. I believe it first started after having the JB+ installed for awhile. I always had the JB+ turned up to the max. Generally the check engine light doesn’t come on. I only see the code when scanning with Carly. I removed the JB+ for awhile and cleared the code, but it comes back. Over the weekend I replaced the TMAP sensor and installed the JB4. After about 50 miles on Map 2, the check engine light came on. Scanning with OBDII gives me P112F and Carly 101F01. They seem to be the same. I don’t think either JB is causing the error code, but it certainly came up much more quickly this time with the JB4 installed. Maybe something happened from running the JB+ at max for so long? Since the code is there even without a JB installed, what else could be the issue? I saw on another forum about an issue with the the high pressure fuel pump. It was suggested to disconnect the tank vent valve and let the vehicle idle for 15 minutes to reset the DME adaptations. If it comes back, replace the ventilator valve, or even the fuel pump. There seems to be a lot of possibilities that can cause the error code, but I would rather not replace every single suggested part for nothing. Any suggestions on what to look for next? It is a 2013 335 with 46k miles. |

Hopefully this helps, I’m literally going through every 101F01 thread I can find because it had me bugging out until it finally got solved Solution: my mechanic replaced the boost solenoid and so far so good! He also found a boost leak on the inlet pipe (MST hose from turbo to intake tube) as well as a fucking ziptie holding the charge pipe to the FMIC from the wack mechanic who worked on my car before the current mechanic (shoutout to Kings Automotive in Bloomingdale, NJ). He reset adaptations for me several times, wasnt going away. Did a smoke test and fixed said boost leaks. Installed new boost solenoid and so far no problems.

I replaced my MAF, both map sensors and did a smoke test for leaks and I�m still getting this code. (2013 BMW F30 335i 6spd, stock ecu) |

(2013 BMW F30 335i 6spd, stock ecu) I don’t believe I ever got that code no.Although I do believe it was accompanied by 102001 code. Sidenote for this whole debacle: I recently had an open ticket w/ Bootmod3 to figure out the high gear low rpm high load stumble. Halim told me to run logs so I sent him stg1 93 and stock tune logs. Of course half the stg1 logs had the stumble and the stock tune did not. Shortly after emailing logs and before reflashing to stg 1, I turned the car on and got the CEL w/ code 101f01. Reflashed to stg 1 and started again, no more code. Halim eventually got back to me and said its my octane and that I should run the stg1 91 map even though I strictly pour in 93 octane without compromise. At this point, who the fuck knows is where I’m at with it haha. I guess rule of thumb, just don’t floor it under 4k rpm in 3rd gear or higher. Good luck! PS, peep my new video |

PS, peep my new video FYI, Running the 91 map with 93 fuel is quite common especially in areas with poor fuel quality. |

It’s a shame, you would think Shell 93 would be true to what it’s rated at but oh well. Anyone here use octane booster? From what I’ve read, it turns the inside of your combustion chamber as well as plugs orange? Is this a negative or simply discoloration? |

From what I’ve read, it turns the inside of your combustion chamber as well as plugs orange? Is this a negative or simply discoloration? Boostane does that, yes. Some people run it quite frequently, but i would not consider it a long term solution. The discoloration is supposedly harmless, but i would be a little concerned if you run a catted DP. Not sure how much it might affect plug, injector, etc, lifespan. Definitely dont run autopart store octane boosters, you need «legit» ones like boostane, VP, etc. If you just want to dump in a bunch to a single tank to run the race gas map for a track day or something, that’s pretty common, even on other platforms. E85 is the best and most sustainable «octane booster» IMO. |
