Hey guys,
here is what happened.
the car is a 2007 BMW E92 335i AT with 107000KM

i replaced the valve cover gasket, Spark Plugs, and the PCV valve. when i started the car, it went smoothly without any problems.
i turned the car off for 1 or 2 hours and later when i turned it on, it had a long crank, rough idle, and black smoke from the exhaust.

i got these errors on INPA.
1)29E0 - Fuel Mixture Control
2)30FF - Exhaust Fume Turbo Charger, low pressure side - Turbocharger 'A' low boost condition
3)2E83 - Electrical Cooling Pump, Low-Power mode

is it possible that my injectors are damaged due to changing the gasket? what would cause this error.

i took the car to the dealership and they said that all 6 injectors need to be replaced along with the HPFP.

another issue that started occurring recently was the electric cooling pump error. but the car is not overheating and i got the engine too hot message once.

Quick (uneducated) guess if you have a ground issue somewhere, or a low battery.

pull the spark plugs again and see if they have oil on them. when you put them back torque them to spec our cars are very sensitive to this. if you have oil then you screwed up the valve cover job. the black smoke is unburnt fuel. Also make sure the pcv operating correctly.
If all else falls reset all adaptions or unhook the battery for 24 hours
Your dealer is stupid dont listen to them, if they were right you have additional codes

i checked the battery using INPA and the voltage is good. no issues there.

thanks twinboost_MD for the reply.
how can i check the PCV operation?

i did a full adaptations reset using INPA but nothing has changed.
how can i locate the leaking injectors? is it by pulling the plugs and checking which ones have fuel on them?

is it a good idea to get used injectors? im thinking of getting used ones and replace them all and sell the car.
i have paid more than 10K in repairs in 2 years now so i kinda hate it now.
