Help Please!! Engine Suddenly Stop

[farisfazilan]

Hello all sifu. Need help. I have main problem with my car E46 325i. Engine suddenly stop while driving. But most of it will happen at toll (smart tag line) and traffic light when the car will getting slow. Then i try to start the engine back and the car wont pull off as it should.. even though i step on the gas the car will go so slow then the engine will stop back. I sent my car to workshop but the mechanic also no idea what is the problem. Already diagnosed but everthing normal. Can you guys help me on this problem. Kindly seeking sifus over here for assistance. Tq

Most likely cause is the crankshaft sensor or camshaft sensors.

Gosh... im facing the same prob for my e46, year 2000 m43b19 currently....

Once or twice in a month i can feel the car is dying when slowing down....steering is super heavy suddenly.....n die...and after i recrank everything start well again...no warning lights come out nor any error code when diagnosed.

Also facing some difficulties when starting engine in the morning, crank the engine but die.... hv to press gas pedal several times then only back to normal start....

Bro Herbert, besides crankshaft sensor or camshaft sensors, any other possible way could cause this problem?

Bro Honsen, pls check all your air intake piping and manifold. The likely possible culprit may be the ventilation / valve cover piping which is joint to a round 3 in diameter air valve behind engine. The valve may be defective due to torn inside diaphragm. Easy fix.

Good luck,

Many thanks for your info OldmanBM, but i hv js changed the CCV crankcase valve thou, i think it is exactly the one you mentioned (part number 11157501567). So far it doesn't die when driving anymore, but still suffer from hard start up once in a while....hmm....

Just change the crankshaft sensor first.

I faced this problem at my car before. I changed inlet cam position sensor.
