My E46 valvetronic suddenly cannot start..

[eri]

Hi everyone,im already introduce myself in newbie section.Sorry not good in english.My car is e46 318i ,2.0 valvetronic. Pagi tadi semasa enjin sejuk, my car tidak bleh dihidupkan. Selepas cuba 7,8 kali then enjin hidup tanpa apa-apa masalah. Tiada RPM jatuh atau jerking masa bawak kereta.Masalah ni cuma berlaku bila enjin sejuk, enjin panas skali start terus hidup. 2,3 hari sebelum failed to start, bila pagi enjin bunyi macam motorboat dalam 2,3 saat then OK.Tapi still bleh hidup cuma harini saje failed to start.Dah run guna GT-1 tapi fault code cuma cam sensor (exhaust) yg rosak. Already tukar that sensor tapi faulty code tidak boleh erase.Tolong sifu-sifu semua.TQ very much.

Bro BlackCat, already cleaned the MAF sensor with CRC MAF cleaner last night.
Bro B33mEr, cam sensor sudah tukar tapi bila mahu delete guna GT-1, error code still ada. My mech said maybe timing lari. Bateri semua OK.
BTW, my valve cover gasket leaking and last week masa tukar spark plug, satu plug basah sikit. Tu ke yang sebabkan kereta tak boleh start and cause missfire?

Bro problem kereta tak boleh start nie jadi selepas tukar valve cover gasket ke? If so check your plugs again and check your coils ... Diagnosing engine problem over the internet nie is a hit and miss ... My recommendation is to get a 2nd opinion from a reputable bmw workshop and see what they say also ask them if they can clear the error codes for you

Bro B33mEr,thanks for your recommendation. will check the ignition coil. Plug i think its ok because already changed last week.BTW belum pernah tukar valve cover gasket since leaking appeared. Already go to WP Auto and Bomin Auto to check but they cannot confirm. Need to tinggal kereta kat situ at least 1 week.
