Noise from rear

[Mike810]

I often get a thumping noise from the rear of the car on start up. Is this normal? I don’t remember it when I first got the car.

I also hear a similar sound when I turn sometimes. Right when I am turning and finish the turn if I accelerate too hard. Like a faint popping or thumping sound definitely from the rear outside the car. Did I damage something in the rear with my hard acceleration and occasional sliding on turns? I have added more power with the JB4. I will let the dealer look at it at next service.

So many possibilities. I don't think that anything is broken. Last summer when I accelerated while turning out of a parking lot there was a palpable "thump" from the front. I think that the ECS gets into play when making those kinds of demands, resulting in "noises."

Let the poor person out of the trunk.

Haha. This is funny. Nobody in the trunk though.

You may be on to something. I did take the spare and everything out of the trunk several times to disconnect the negative battery terminal. To reset the ecu for jb4 tuning problems. Maybe I didn’t put something back the way it was.
