So this is going to sound really crazy and I am sure it is "normal", but I have researched and come up with nothing.

When I get in my car for its first drive of the day something pops under the car at exactly 30 mph. Every time!! Sometimes I think I can "feel it" under the driver side floor board, other times I cannot.

The first time it happened I thought I had a rock in a tire that got thrown out, but I have tested that. Also if it was that... it would not do it every day.

Also I know that the doors auto lock, that is not it. Obviously this is a different sound. Anyone here know what it is?

 

Brake system does a check of sorts. Normal. I can't tell you a lot about it though, because some people seem to notice it loudly, others don't notice it at all. I'm in the latter group.

 

Thank you for that info. I figured it was something like that, but I cannot believe it pops so loud. I knew you guys would know...

 

I get the exact same thing except mine sounds/feels like a tiny fart of sorts.

 

i never noticed it until i had my eibach pro kit installed on monday and now i notice that same "pop" when i first start moving after sitting for a while...does that make sense?

 

I've had the same issue (drivers side) since my Eibach install also. I have been under the car checked and re-tightened everything, even replaced the transverse link but to no avail.
I have come to the conclusion it's something shifting possibly the spring and strut seat, even though I took special care to locate the coil within the seat notch.

 

ABS system does a self test shortly after startup. when you start moving, it does a quick engage with the BRUUUUuuuung noise to make sure the systems working as it should. does it even if youre accelerating and not touching the brakes. completely normal, my 3rd gen did it all the time

 

I have the same noise on the passenger side. I came to the same conclusion.

Thanks for the info as some of the newer owners might not know this.
I've owned this car for four+ years so I know very well the noise difference between the ABS self test and the post Eibach clunk I feel in the left front suspension.
This topic has actually been discussed in full on prior forum posts.

 

Great info I never noticed this until I read it and then went for a drive the next day, thanks!
