rquinley

Every time I drive my new A4, I first get the "clunk" from the door locks (normal) as soon as I start forward motion but then, always when the car reaches 25 MPH, there is a double "clunk" sound coming seemingly from the car's underside or perhaps from under the hood. Anybody else with a 2017 A4 notice this and if so can advise what causes it (normal?)?

Normal. They all do it. I believe it has to do with the ABS

And with it not being explained at delivery.

I think this forum definitely needs a sticky thread and this should be the first entry. :-)

I wonder if it's in the owner's manual...

... but yes, this is probably THE #1 'complaint' about the car around here.

No clunk from my car anywhere near the areas that rquinley is referring too. If it loud enough to be heard from under the bonnet or underside that must mean it is very loud.

Maybe it's a North America only thing, but the car will "click" the first time it hits 25MPH/40km/h in each drive cycle. I don't think it's a big huge deal and it's not especially loud, at least if you have music playing, but it is audible.

If the non-North American cars don't do this, that would be very interesting.

(Random question: folks with North American manual transmission cars, do your cars do it too?)

I have a manual transmission and I do get the "clicking". It's something that I hardly notice anymore, though.

Me too, USA, 25 MPH click. I sort of feel it in the steering wheel pedals but to a lesser or greater degree each time and other times not at all.
