Well recently the car started having light vibrations when idle,and the most i noticed it was when im idle in neutral and i press the gas pedal and then i release and it vibrates on release 

I change all 4 fuel injectors,replaced both engine mounts,cleaned the EGR valve,changed the fuel and air filter

I dont think its the flywheel because it shifts nicely into gears and the car dosnt shake at all when im moving  and when i press the clutch the vibrations are still the same 

And as far as the driving is concerned, it's flawless, pulls  from low revs, it works great, it starts right away , only those slight vibrations when idle, I can't get rid of them at all, and I noticed that when I turn off the car i hear a slight vibration aswell really small one like an engine shake 

 

were the mounts you changed similar to these inner ones..https://www.ebay.co.uk/itm/276272658622?fits=Car+Make%3AAudi|Model%3AA4&epid=19033743447&hash=item40532238be:g:jtQAAOSwLdRlnBkK&amdata=enc%3AAQAIAAAA8Dm7JESF4DgpvNz3BLl7e%2BPBzCXCz7LEPnY2kV1cWXK21ABRYCnl%2Bq5TOqZUAiM2KDhPcnAl9Dy5Du1lShERJEG9Ln6sTLXBFSaEk%2FO329T%2FCYFuBkIUldlQwZWzHIHihkWBSQsjUXXr%2BT01a4vIhSApG%2Ba8tv6aSv%2B1nmQ4D79GO%2BXFlfWisguxW7qQp8JnwPXOXDU3kq4hUHVpMntDSwEopXg%2FoW62RtRQMSFG5gdEi9D8TSkgHJ3w4MbP3hYG6A%2B70QJUKx0%2F5ZWQzfH1eTvhLHZeTHntQ54seMiNEXECEGsRRL2RRHzsjDnSMkENiw%3D%3D|tkp%3ABk9SR4TBsbedYw..

Ugh i cant tell u excatly cause the mechanic bought the mounts for me and replaced them i remember he showed me the old one they had like an orange connector 

and i payed 200$ for both thats all i know

Hey, I an having similar issues with my '11 A4 Sline 2.0 TDi. Just like you, my vibrations are clear when i accelerate and let go. Sometimes, the car will shake when cold, when it's warm it will still shake but ever so slightly. Had it serviced, did the same procedures as you and no luck. Any updates on yours? Thanks!
