I have a manual transmission Golf 7 TSI from 2015 and when shifting in the lower gears(1->2, 2->3, 3->4) there is an audible clunk when engaging or disengaging the clutch. This however only happens when the engine is warm. For about the first 20 minutes of the drive there is no clunk. The clunk is not loud but audible when you are paying attention to it. I tried recording the sound with my phone but that didn't work.
I don't know if this is related but the clutch pedal also starts making creaking noise when the engine is hot.
I googled for a bit and most of the search result suggests the motor mounts or dog bone mount is loose. This would make sense to me if the sounds was present from the start, but on my car it only starts when the engine is hot.
What could be causing this?
