new W205 'Pop' from undercarriage when accelerating from stop

6 posts in this topic

Hi all

 

Seeking some advice from experienced folks here. Have a month old 2018 W205. Car cranks and moves off from parking without much issues. However, shortly after moving off from stop (i.e. traffic lights), it'll have a distinctive 'pop' or 'spring-like' metallic sound that seems to come from the undercarriage.

Problem goes away after driving for a few minutes though, and it is usually observed after car have been parked for some time or during cooling weather.

Any guys here facing such issues? Appreciate all feedback.

Thanks for the reply. May I ask if you turn off the eco start stop as well as the auto parking mode?

Came across a topic similar (somewhat) to your question. FYR..

Two likelyhood:  1:  the auto start-stop activating the engine, or 2: auto releasing of the brake-hold.
