Hi all,
Just recently my '05 TT started making a strange noise under very specific conditions. When the outdoor air temperature is between roughly 32f and 50f, the car illicits a strange "groaning" sound when I use the brakes while in reverse. When the air temperature is either warmer or colder there is no such noise. And the car otherwise drives normally. I doubt it's anything serious. But, with the weather getting warmer, I'm afraid that I won't be able to reproduce the issue when I bring the car into the dealer next week. So might anyone here have any idea what might be causing this "groan"? Or perhaps know of several things to look at regarding it? I figure it will help with the diagnosis if I can tell the where it might be coming from.
Also....an unrelated question while I have your attention.
Within the past week the car started doing another odd thing -- or rather not doing it. Typically, when you press the "lock" button on the keyless remote, the horm chirps to confirm that the car is indeed locked. However, it has stopped doing so. When I press the "lock" button, the car does lock and the alarm indicator lights begin to flash as they are supposed to. But the horm doesn't chirp. I don't think that it's a case of a bad door sensor, because as I said, the alarm is visibly arming itself when I lock the car. So what could it be? Might I have unwittingly changed a software switch that enables/disables the horn chirp? I'm at a loss.
Thanks in advance for any assistance or ideas you might have.
