Странен проблем с Х3 2.0д
Колата вдига до 2000оборота пуше бяло и прекъсва.
Откачам дебитомера и първия път когато подам газ пак прекъсва,отпускам газта пак давам и всичко се оправя и върви без никакви проблеми.Сменил съм 4 различни дебитомера,софтуерно съм го изключвал и пак същия проблем.Излизлиза посочената грешка.Смених дюзите на 3ти и 4рти цилиндър и все същия проблем.Никой не може да разбере от какво е.Някой ако може да ми помогне ще съм много благодарен.

Re: Странен проблем с Х3 2.0д
Ако питането ти е за двете грешки за дюзите, отговора е:
If an injector is replaced, the following service function must be carried out: Injection quantity compensation.
И процедурата е:
Please note the following information on the diesel engine diagnosis:
Injection quantity compensation
Important: when replacing piezo injectors, observe the imprinted code.
The following must be ensured when piezo injectors need to be replaced:
the imprinted alphanumerical code on each piezo injector must be assigned to the correct cylinder in the DDE control unit.
The BMW diagnosis system has the service function ”Injection quantity compensation”. With this service function, the code for each cylinder can be changed and stored on the DDE control unit. For cylinders that do not need a new adjustment value, the previous adjustment values remain unchanged in the DDE control unit. Injection quantity compensation must also be performed if the DDE control unit is replaced and communication was no longer possible with the old control unit. The codes for the piezo injectors installed must be read off and stored in the DDE control unit.
Mean quantity adaptation
A deviation of the injection quantity is ”learned” in an adaptive characteristic map. This characteristic map is permanently stored in the DDE control module (EEPROM). The characteristic map must be reset (deleted) in EEPROM if any of the following components is replaced:
Mass air flow sensor
piezo injector
Rail pressure sensor
For resetting the data map, the BMW diagnosis system has the service function ”Mean quantity adaptation”.
С две думи да се изтрият адаптациите на дебитомера и да се вкарат нови кодове за дюзите

Re: Странен проблем с Х3 2.0д
Адаптацийте на дебитомера ги изтрих ,а на дюзите си въведох същите кодове които са на дюзите и пак не става нищо.
Re: Странен проблем с Х3 2.0д
Проблема е решен.Изчистих егр-а и всмукателния колектор и всичко се оправи.
