[QUOTE="MetroPoLs, post: 722891, member: 44044"] I've a BMW 3.18i N42( Vin last 7 digit: CK02302) and there's a problem that i can't solve. In the morning when i run the cold engine, start properly. After warm up phase when the temperature gauge at the beginning of the blue area, if the gear position at "P" the engine is stopping suddenly either the position "D or R" the engine is shaking like crazy and intermittent cutting during 3-4 seconds and shortly after engine is returning the normal and working properly. When i unplug the eccentric shaft sensor (near the oil cap) and start the engine this problem is not. In the video that I recorded with DIS. You can see the issue at the "Operation mode : transition throttled" phase (from "throttled, warm up" to "valvetronic operation") the engine is intermittent cutting during 3-4 seconds ) [B]Video link:[/B] [URL="https://www.youtube.com/watch?v=YTLyAa3SUcQ"]https://www.youtube.com/watch?v=YTLyAa3SUcQ[/URL] [I]Replaced parts[/I] [I]Spark Plugs[/I] [I]All Filters[/I] [I]New tpye replaced chain tensioner[/I] [I]Vanos adjustment unit, inlet camshaft[/I] [I]Cylinder head cover profil gasket[/I] [I]Vanos Solenoid orings[/I] [I]CCV valve and pipes[/I] [I]Cranck sensor[/I] [I]Temperature sensor[/I] [I]Both Camshaft sensors[/I] [I]3 Lambda sensor before catalyst[/I] [I]Vanos timing controlled with special tools and Eccentric shaft sensor, Valvetronic actuator motor and DME relay( in the black box) were swapped by another car is running properly[/I] While searching this issue on the net i found a link about that problem ( my car is not affected production range but the problem is very similar with my car) and i reprogrammed the DME with Winkpf program using SP Daten Files v50.2.
