Problems, ESP and Whine

Now ive had 2 x A4 avant (B6's) TDI's and 2 x VW Caddy TDI's so strange VAG faults are common for me, but my new b8 avant has the ESP coming on regular and stays on saying ''take me too your dealer'' (not really) but similar.

But then i read the post about the alternators causing esp faults, now my turbo sounds like a electrical whine and no other TDI ive had sounds like this, i thought it was because of the better sound proofing causing me too here turbo whine more, but i put 2 and 2 together and thought that mybees its my alternator im hearing?
