P1290 ошибка bmw

Коды ошибок по маркам автомобилей

Из чего состоит ошибка

В пятизначных кодах первый знак обозначает принадлежность к системе, в которой обнаружена неисправность:

• Р — неполадки, зафиксированные в работе силового агрегата либо автоматической трансмиссии (АКПП);
• В — неисправности, связанные с функционированием кузовных систем — электрических стеклоподъемников, подушек безопасности Airbag (SRS), центрального замка и т. д.;
• С — коды ошибок в работе шасси или ходовой составляющей транспортного средства;
• U — неисправности, связанные с электрикой или электронным оборудованием, взаимодействием между управляющими модулями, цифровым интерфейсом.

Второй знак обозначает:

• 0 — общая цифра для всех OBD2 кодов;
• 1 или 2 — код производителя транспортного средства;
• 3 — резервая позиция.

Третий знак в комбинации неисправности указывает на тип поломки:

• 1 и 2 — сбои в функционировании систем подачи воздуха либо топлива;
• 3 — неисправности в работе системы зажигания;
• 4 — неполадки, связанные с функционированием систем вспомогательного контроля;
• 5 — сбои в работу элементов системы холостого хода;
• 6 — неполадки, зафиксированные в функционировании электронного блока управления автомобилем или его электролиниями;
• 7 и 8 — неисправности трансмиссионного агрегата.

Последние два знака обозначают порядковый номер неисправности.

1. I’m getting a check engine light and P1290 OBD code that from generic searches is showing to be a faulty cylinder head temperature sensor. Very little information on the part, replacement, or this code number in general so I was wondering if anyone had experience with it. The car is a 2013 328xi. Not much in the way of symptoms, maybe some weaker performance than usual and previously I was getting a bit of hiccup right after I started my car but not much else. Do I need a specialty BMW code read for more information? Anyone ever seen this code?

   Thanks!

2. That’s why generic OBD codes aren’t much help. If you can get it scanned with real BMW software, it’s going to be a lot more specific. It could be a thermostat code, or something else.

3. BT codes show 123401 and 123431, having to do with the electronic wastegate. I’m suspecting a bad actuator, but I am out of my DIY realm now. I will follow back up here in case anyone has the same problem once I get it figured out, since the info on this is still pretty sparce.

4. For reference, it did turn out to be the wastegate actuator. Fixing that fixed the check engine light and improved mpg.

5. Hello Zack.

6. Hi,
   Codes show the same issue on my 125i F21.
   Are there any new information?
   BMW says the turbo has to be replaced.
   Costs about 3k€.
   Whats do you think?

   Regards,
   Fabian

   I have a 2013 328xi also. While driving at about 35 mph, my car suddenly lost almost all power as if I was running out of gas (nothing electrical). I managed to get pulled over safely and saw the check engine light and a display saying �drivetrain malfunction�. This display had come up once before when I pulled into a parking spot and stopped, but the car ran fine. I called the BMW shop and he said to shut the car off wait a while and see if it was on when I started it again, which it was not. The display has come on two more times (usually when parking), and has done that poor power thing once more but not nearly as bad. And in case you�re wondering, I am very careful about making sure my car is completely stopped before putting it in any gear. Anyway, I was wondering how much it ended up costing you to fix the wastegate actuator on your car. Were you able to fix it yourself or did you have to have it done at a shop?
