琴日小弟部2011年323I 用車發覺車好震,同轉數錶跳黎跳去,好唔穩定,開車後發覺力水差左好多,同埋發覺引擎故障燈著左,停車開車一踏迫力就好震,因為已經行駛中,冇辦法停車,後來楂左5分鐘又發覺引擎故障燈熄左,行車又順番,咁就照楂去車房,當到達,車房師傳著車時就著唔到,師傳話係引擎入面螺絲斷咗,2個蝴蝶返掩到期,其他野要左檢查,想問下其實我架車依類問題,嚴唔嚴重,要整幾錢度?

反而我初步估係火咀或點火coil問題

車房師傅咁勁, 撻唔到車就知道引擎入面有螺絲斷咗?

Sorry 我講唔清楚,後尾著車俾油俾冇動力,同埋引擎折開偈油蓋有個位係會轉,佢轉唔到,所以話螺絲斷咗,但都係初步睇,今日佢先幫我深入檢查

相中紅圈位置,我只係見師傅開左依個蓋用燈照,話我知俾油時依組野冇變動,咁係螺絲斷咗,要左詳細檢查先知道(圖中唔係本人車,同埋用圖表達清晰d)

叫車房唔好玩啦,引擎組件邊有咁易斷,除非斷 cam帶,但斷 cam帶你又揸唔到去車房啦,快D攞番部車,唔係就唔止斷螺絲咁簡單

with your car, i assume your car is N52N engine, which is newer version of N52...

For your case, I have same situation as yours before, while finally identified is one of the ignition coil goes wrong...

it start driving very rough and engine light turns on after 1 minutes of roughness... and i keep slight throttle over few minutes, and it suddenly become smooth again. and engine light turns off, but the power isn't real good.

when attaching to BMW computer, you should find a cylinder misfire code stored in DME.

For my real case, i found that one of the ignition boot is cracked and causing misfire, there are so many reasons having misfire, my case is just for your reference. (i saw some is valve cover seal leakage, got so much oil stucked inside the sparkplug coil hole causing misfire, etc)

Regarding the oil cap in our N52 engine, we need to push down the surrounding cover in order to turn it over, just give a little power and it should turn, that part is simply a cover does not have any screws inside...

Regarding the throttle body, please avoid changing, as throttling logic in N52 is mainly controlled by valvetronic (VVT) motor, instead of the throttle body(only used as fallback if VVT motor goes aways), so if c-fu asking you to change entire throttle body, that's non-sense.. and probably he don't know much in N52 engine.

As other c-hing suggested, just change a trustable 車房.
