GTI 1.8T - Cold Start Secondary Air Pump Sound

[@Kl3mo]

Thank you so much for this. I went to the mechanic multiple times trying to figure that sound out. Changed my belt and tensioner earlier than i needed. Turns out the mechanic didn't know either

Been looking forever to find what the loud whistle then sealing sound was for a long time. Thanks for posting this up.

My skoda Octavia vrs (same engine 180bhp) does this every time I start it for about 3 minutes always has done it's normal!

Its not normal. The pump needs repairing. Just take the pump off and replace the 6 rivets with 6 bolts and its sorted.
