My Golf R 7.5 creaked badly after the first year, sound came from the back of the car it seemed, mostly when reversing slowly and turning, they replaced some mounts but never fixed the issue completely, creaking was better but still there.
Now my MK8 Golf R is doing the same thing, when driving forward at slow speeds you hear a creak now and again from both front doors it seems, only slightly when moving forward, but in reverse the creaking of the doors are much louder. It could be from the chassis or somewhere else, hard to pin point but odd it sounds like its coming from both doors. Doesn't always do it and VW said pop in to demonstrate which could be a waste of time based on experience. Seemed to be worse when the car was hotter with the weather. This morning its colder and car did not creak!
