Hi all,

My BMW X5 e53 has got a strange symptom: when start most of the time’s after few seconds of smooth work it starts to sound like it’s not working smoothly anymore, like a misfire. Felt lost when put in gear, whole car shakes!
This does not affect the performance. Also after a while of driving this symptom goes away.
Any ideas what can it be?
Thanks!

Could be a number of things including the torque converter not locking up, you really need diagnostics.
