CLA45 hesitate to move
Hi guys, I’m driving a 14’ CLA45. Just gotten this car bout a year ago and recently I realise that the car got problem moving off from a complete stop, it’s like the car hesitates to move off but it only happens randomly. Xentry did not show any error. So far I have replaced the MAP sensor, boost sensor and the airflow sensor. PCV hoses has also been replaced... can anyone help??
this only happens around 1-2k rpm. And before this hesitation happens my rpm will hunt

Well you might not want to hear this but the early 45s were known for transmission issues. The hesitation was usually fixed by a transmission replacement. Try changing the transmission oil as well as filter and have Mercedes test the valve body. If there are metal shavings in the oil and filter you may need a new tranny. Did you get extended warranty? If not, think about selling it before it gets worse and you can’t sell it anymore.
