[Rinos]

Hi guys
I need some help
I have an E92 320i
--- Last November i got the engine management light and the car was shaking immensely
It was still within warranty so they changed an ignition coil and was fixed.

--- Around march i got the engine management light again and took it in. The mechanical engineer said it was probably because i had too little gas in the tank and the car might have sucked air.

--- The last month i was getting huge hesitations and lately with the A/C on i could not drive the car. I took it to the dealers and picked it up today. They changed the following:

1. Knock sensor
2. One ignition coil
3. NO2 sensor

--After just a month the car is again kaputt

Can anyone tell me if there is a Service Information bulletin concerning this problem?

Thanks, appreciate any help
