Serpentine belt noise. on 2008 Volkswagen Jetta

Took my car in for a fuel line recall & noise problem around the serpentine belt area. Dealer did a sound diagnostic test & said that the tensioner pulley located underneath alternantor was going bad and that both idler pulleys and another tensioner pulley where also going bad. Had both upper & lower idler pulleys replaced & tensioner pulleys replaced by a VW Dealer. Still getting that whizzzing noise somewhere near the AC or Alternator. Any suggestions of what might be causing the noise? Please help.

I would take it back to the dealer and make them explain/warranty why there diagnosis didn't fix in the first place. After all they replaced everything but the kitchen sink.

The work would have had nothing to do with the recall. The 20I4 campaign is to remove a tab from the washer res. that has the potential to rub the plastic fuel line. Have them check the pulley on the alternator or the a/c compressor clutch.
