Car jolts sometimes when i acceperate

[amebb]

Hi there

I have an issue with my BMW X5 (e53 automatic Diesel 170k) when i am driving.


If i am gently accelerating and then lift my foot from the accelerator pedal and let it drive for a few seconds before i accelerate again, I get a clunk sound/jolt.
its hard to explain as it almost feels like someone has driven in to the back of you and you get a jolt moving forwards.


This does not happen all the time. I have noticed it happening when i drive hard and then slow down.



Has anyone else experienced this issue and what can it be?


Any help much appreciated.


Thank you
