Hot Idle Stall and rough idle E93 2007 N53
Hello, this is my first post here
Unfortunately, I'm having a headache solving this issue. I have an Auto 2007 e93 with the N53 engine. On cold start the car starts fine and drives fine - always However consistently after the car has warmed up after about 30-40 minutes of highway driving or hot day etc - when i approach stop start traffic/the car is idling - the Check engine light comes on and the revs drop to 0. It used to previously rough idle for a bit but now it just drops to 0 and stalls. If i immediately try to restart the car there may be a long crank and CEL may still be on with a really rough idle and poor acceleration otherwise if i restart it may just start as usual and i can continue driving. Normally after a restart or waiting a bit it resumes back to usual and i get scared seeing red lights... I just had the all the injectors changed to index 11, all new coils and all new plugs. They were previously all mixed indexes from 2,9,11 and all the coils and plugs had been fouled with oil, carbon build up after not being changed for ages and plastic seals had swollen around the coils. We thought that was the cause. Yet after a 45 minute drive today and sitting at a bus stop in park for 10 seconds the engine cut out with the CEL again. I called up the local indie bmw specialist and they said they were disappointed the fix didnt work and it could be camshaft/eccentric sensor (i forgot which one he said) as I mentioned the long crank. I plan to bring it on monday. What sources could there be? I have a video i filmed when this happened too. Most recent codes are NoX Sensor and Low pressure fuel sensor but I don't have any code reader myself - any help would be useful. I found a way to circumvent this was to just stop the car at every traffic light and turn it on when i wanted to move which is really annoying! Thank you for the help |
