Vag-Com Adapter: Compatible with New Audi A3?

Hello.
'About a year ago, I bought an original adapter (from VW with a built-in serial interface) on eBay. With it, I was always able to log into my old Audi A3 (year 2000) without any problems using VAG-Com. Can I use this adapter to log into my new A3 (which I have ordered)? It is known to have a CAN bus. Or does that not matter?'

Then, another question:
Since I had problems with my old car's VTG after about 2 years, I would be okay if the EGR valve were to fail . Is it possible to use the methods described in the forum for the 1.9 TDI engine of the new A3?

Sure!

Best regards, Hüso.
