Audi S4 2011 Front end tap

[Bob123456]

Hi All
New to this but need some advise.
Currently have a S4 2011, I don't know if this is a common problem but when pulling away slowly in drive and the car goes from 1st into 2nd gear (driving slow) I get a single tap? sound from the front end (it's annoying now as I keep hearing it) and if I select manual and keep in 1st gear I get the same noise @ 1500rpm.
Have taken to Local Audi dealer, took the engineer out for a listen and he agreed to the noise, now after a couple of days of investigating from Audi I have been told it needed a software update on the gearbox then to be told it's a common thing on these models but could not test this as they don't have one.
All I ask is can anybody who has this model please test it to put my mind at rest.....
Kind Regards

I had something similar on my 61 plate S4. I noticed it the most when the windows were down and it was more of a rattling sound. Turned out to be something on the exhaust that was "excited" by the engine revs and gear change. Exhaust replaced under warranty and the noise was gone! However, this was a rattling, ticking sound so may not be the same thing.

Hi, the tap? Sounds like it's from the gearbox but you only get it when you are (stationery) pulling away slowly, if in manual 1st gear I get the sound about 1500rpm if in drive 1st going to 2nd (slow) it happens again???
