MK6 GTI Multiple Cylinder Misfire

If the check engine light is flashing you shouldn't drive the car. Bring it to the dealer. Sounds like it could be the classic intake manifold flapper thingy failure and/or carbon buildup which has probly gunked up your injectors as well.

Dealer won't do anything for the manifold warranty unless you're throwing those codes. While they are replacing the manifold have them do the carbon cleaning.

The cleaning is all you should have to pay for. If they replace the manifold and don't do the cleaning, you're car will still misfire and run like poo poo.

Carbon clean should only be like $200 if their already doing manifold under warranty

I dropped the car off at VW last friday, just got news from the mechanic, he says the timing chain and tensioners need to be replaced... could this cause the misfire? I just want to be sure before I drop $1,000

No problem, But at your mileage i would do the timing chain service. However, it wont solve your misfire issues. Hopefully, its carbon build up, Most likely at your mileage if it hasn't been done before. I would also replace the Manifold for the newest revision. The older revision had issues with the flap motor arm. I had a similar issue as you, however my car misfired only on cold starts. Which signified Carbon Buildup, then i also received the intake manifold P2015 code. Had the manifold replaced and carbon cleaned, and has been good as new since.
