Проблеми с дюзи 2.0 тди 170hp


termitkoter

Recommended Posts

Здравейте колеги,

 

Установих, че имам проблем с дюзите. Мотора е 2.0 тди BMN двигател. Оплакванията са труден първи старт на мотора (пали като с ритник), грубо гаснене на колата и някакво гадно тресене на празен ход на колата. Демпфера е чисто нов няма как да е от него, 

Ако може някои да ме посъветва и препоръча сервиз, къде може да отида в София за да направят качествена диагностика на тези дюзи. 

 

Благодаря Предварително !

Тези симптоми защо ми напомнят на EGR и дросел. Но знае ли човек.

Отиди да те закача на компютър и сравнете стойностите в Meas. Blocks cъс стандартните такива, за да се ориентираш къде са ти отклоненията и съответно проблемите:

Благодаря ти за инфото. Може ли да ми препорачаш сервиз в София, къде може да ми свършат работа кадърни хора, защото разбирачи и хора които искат само да ти вземат пари има много.

  

Като цяло доста често излиза на компютъра задрасттен ДПФ филтер. Пускаме му регенерация и след една смяна на масло (10 000км) пак илиза че е запушен. Дросела и него го отварчм профилактично. Адки гадна чернилка се затлачва точно на клапата като мн твърд пластелин и се чисто мн трудно, Идва от тръбата от към ЕГРа.. Но като цяло вибрациите и трептенията са на моменти.. Но влезе ли доста разтриса колата и пали буквално като трактор.

За сервиз, не бих могъл да ти препоръчам. Рядко давам на някой да пипа по колите ми и задължително го гледам в ръцете. В това отношение съм отвратителен клиент. Но бих могъл да ти препоръчам диагностик. Аз лично съм впечатлен от него, как за 5 мин. разбра, че е променян софтуера на двигателя, за да се скрият проблемите. Но, той не пипа колите, само им прави диагностика.  За ремонта си търсиш сервиз. Даже отказа да ми налее оригиналния соф, въпреки че имаше щялото оборудване.

Благодаря ти много за информацията. Ще се свържа с човека и ще видим какво ще излезе според него.
