Hello together and a happy new year! I have a problem with my VW EcoUp (BJ 2015, 110.000+ km, regularly waited) and hope one of you has an idea: When starting or starting, especially with a cold engine, occasionally a strange noise occurs. Here you can listen to it:https://youtube.com/shorts/vQYw8PEf4mQ?si=yfApNLI3c6BYzn6T I was already on the lift – all axles, wheels and moving parts were checked, except for the hot exhaust. Unfortunately, n The sound could not be reproduced at that moment either, since it does not always occur. A few observations: In idle one does not hear anything, even if I give gas. The sound occurs more often when the engine is loaded, e.g. when it is starting up uphill. However, it remains silent. I am at a loss and uncertain how to proceed best. If someone has had similar experiences with his VW Up or a conjecture about what it might be. Thank you in advance!
