Default Odd croaking sound from passenger-front corner

Hi All,

I've recently started to hear a somewhat speed sensitive sound coming from the passenger front corner. It becomes prevalent around 30mph, speeds up slightly as I get to 40mph, and then maintains it's cadence around that speed. Can't hear it with music on or windows down.

The sound itself sounds kind of like a muffled frog croaking. Confirming there are no frogs in my area of Utah! I'm taking it for an oil change in the next thousand miles or so, so will get it checked then... but wondering if the brain trust has experienced anything similar?

I have a similar sound that can't be defined exactly. I did a Topix search for this: it may be a sound from the torque converter of the automatic transmission. It also lists a methodology for service to correctly determine that this is this particular fault. Will they disconnect the transmission control unit, etc. It is even stated that it is a fault which does not compromise the use of the car. Only certain series of torque converters do this. I have a 110 P400 MY21/22. Check it out in the US I'm from Europe. I am taking the car to the dealer for service on Thursday this week and will see the result. Bye and keep it running !

Check the A pillar cover. Very well known issue. Many TSB's issued on this
