Need to do a leak down test but at this point with 150k miles I'm going to buy a new used motor with 40k miles for $1500. I am pretty sure its valve guides,seats ect..would likely be cheaper to repair head/valves but since I'm doing the work would rather have a low milage motor. I burn a quart every 500 miles!
Probably oil control rings. I've heard the pistons were designed poorly on early models and the drain back holes get coked up with carbon and the rings then get stuck in their grooves. You can have good compression with stuck oil rings it seems. If I swap motors in the future I will likely go with a 2015-2017 Tiguan engine with the best odds of having revised pistons/rings.

Alright heard back from the guys at Metric Autosport.
Definitely the oil seals in the turbo.
