Audi rs3 vibration from rear problem

[Lior.s]

hey all
car has no faults in vcds

my problem:
when i drive on comfort everything is ok,
but when i put the quattro to dynamic (or drive in dynamic on d mode) and i drive on low rpm gears 4-7 i can feel on 1500-1800 rpm some vibration (its not all the time)
and i sure its come from the rear diff/haldex beacuse when you put the quattro to dynamic i think its give more power to the rear
so i went to the audi company and they say its normal and they dont feel nothing
i have also some vibration on full lock or turns but they change the diff oil and its feel better now but i also sometimes feel it
car has just 19,000km stook

some ideas ?
thanks

Has the Haldex oil and filter been changed? The Haldex filter clogging is common but not included in the list of work even when the Haldex oil is changed.

The filter not changed just the diff oil
Filter can make this issue?

I've read many posts on briskoda from Skoda 4x4 owners of Haldex problems that have been cured by cleaning the filter - which on inspection has been seen to be totally blocked by gunge.

Will it cure this issue? Can't say for sure, but it's worth trying as it's cheaper than replacing any major components!

I have seen some GEN5 units clogged solid at 20k miles but 19k klicks is a bit low. Most of what was on this one either stayed in the unit or fell on the floor.

So they change the haldex oil and filter
And no change when drive straight
Still little vibration/noise on low rpm high gear just when the quattro on dynamic mode
But i checked when I disconnected the haldex fuse
Everything perfect.
Audi also said they dont feel nothing but its bulshit
Some advice?
Thanks
