ID these noises
Two noises, unfortunately I can only replicate once for one of them. 996.2 Tiptronic C4, cabriolet. Here goes:
- first noise happens occasionally when there is a bit of force moving off or slowing down, coming from the rear. Also when the car is driving across two areas with different heights. It's like a 'clunk' or 'snap'. You can hear that in the video at 00:01. The car was being different into the garage which was about 50mms higher than the driveway. I'm planning to take this to the dealer to troubleshoot. There is no leak etc. From my crude attempt to see whether something is about to fall off, by holding and shaking things, seems that everything is tight and not moving around in an alarming fashion. Perhaps this is a sign that the engine mounts need replacing? Mine should be the original hence it's 13 years old.
- second noise. I had once posted it here with no joy. The dealer and indi had both listened to it, and both could offer no explanation. The noise comes on after the tip selector is moved from P <-> D, or P <-> R or D <->R. You can hear the noise at 00:05, 00:12 and 00:19. I was moving the car in and out of the garage to make the 1st noise again. The transmission pan gasket and filter have just been replaced as the gasket was seeping oil.
Any ideas?
