I believe it is the clutches engaging. When your foot is on the brake the clutches are disengaged. Try it and see. Put the car in neutral and keep your hand on the gearshift. Press & de-press the brake. I'm sure you'll feel the click through the gearshift.

It happens ONLY when the auto door lock engages. If you drive for a long time (in a parking lot, for example) at a speed low enough for the auto door lock not to turn on, you don't feel the vibration in the pedal until such time as the Auto Lock engages. I now notice this on mine every single time I drive it.

I turned off the auto lock from the MMI to see if it was the auto lock. The click/quick grinding on the gas pedal still occurs.

I stand corrected. Still probably nothing to worry about though since we all seem to be getting it

I finally had a technician at a dealer hear/feel the click while driving my Q5. He agreed that it's an ABS check and said it was normal.

Personally I think it's way too loud and grinding to be normal. Plus, I've driven plenty of cars with ABS and never heard/felt this on any of them (including the multiple other Q5s I've driven recently).

Please understand that if you haven't experienced this, it really is a bad feeling and even though I now know what it is, it still makes me cringe every time it happens b/c it feels like something is so very wrong.

Has anyone had this 'problem' and had it disappear (either on it's own or via a dealer fix)?

Thanks.

my G35's ABS check is even louder. its a 2003. I've noticed that the ABS systems in cars have evolved a lot over the years. they used to feel weird but they no longer make the pedal feel mushy and grindy noises. i like it and i think the check lets you know its ok!
