HELP NEEDED !

I own audi c6 2011 3.0T, gear is dual clutch 6 speed.

I get a strong knock (Almost like the car wants to jump) and one knock sound only when shifting from Park to Drive position. First couple shifts from P to D are very hard on the car, it gets better if you drive the car for a while. I will try to post a youtube video later today.

It does not happen when I shift to reverse, and the gear shifting while driving (1st, 2nd, 3rd, etc gears) are fairly smooth.

My engine mounts were recently changed.

Please advice is anyone experienced similar issue, or what do you think the problem is.

Thanks !

I'd be checking the snub bushing, on the front of the engine at the bottom of the
the radiator framework. That bushing wears over time & allows "slop" in the drivetrain. The bushing is relatively inexpensive & easy to change.
If it is due for a replacement, get an OEM unit, unless you're an aggressive driver. Then, get a polyurethane one. They're a little harsher at idle dampening.
I put in a poly one, & wish that I had done an OEM replacement.

Thank you for the advice, I actually changed my snub bushing last week, it was completely missing, I was almost 100% sure this will solve the problem, it however DID NOT ...
