engine starting

Hi all, Firstly hoping you are all keeping well amidst the corona pandemic! I have encountered an issue with my VW Eos. I have plugged a fault code reader into the car, and received the following fault code -> 0065 (Turbo/Super Charger Underboost)...

My 2010 EOS (automatic) had the 45K service last Thursday. I didn't drive much until Saturday when I was going out for shopping, etc. To my surprise, the car became hard to start (never like this before)! It took me 3 tries to start the engine. And I drove for over an hour, parked a few times...
