This is a late response but I just saw your post and it's exactly what happened to me when I took my 2018 GSW 1.8 TSI 4Mo in for the 20k mi service. They filled it with 508 00 0W-20. I didn't catch it until much later and I changed the oil myself at 27k mi with Mobil 1 502 00 VW approved 0W-40 oil.
I did my own oil/filter change at 27k mi with Mobil One European Formula 0W-40, since I'm a little uneasy about 10k intervals in So Ca stop and go traffic and 100+ F heat.
I use castrol in my 2014 cx5.
I've been using 0W40 Euro Formula from Mobil 1 for years in both my cars. You will be fine running it.
I use Castrol Edge European Formula 0W40 for all of my VWs (2005 Phaeton, 2014 CC 3.6, 2017 Jetta SE and now a brand new 2019 Alltrack SE): I buy it from Amazon, for $ 24.47 for 5 qts. The oil has a "European Formula" label on the front and specifically states "VW 505. 00 and 502. 00 " on the back, and is made in Brussels, Belgium.
I got some Castrol Edge Titanium FST 0W40 which is VW502 00 approved. I decided to try this oil as their name is on the oil filler cap, as in the past with other cars I always used Mobil 1 0W40.
As a Mercedes-Benz guy, I've used Mobil One European Formula 0w40 in them for decades. It is very good oil. I have well over a million miles on Mercedes-Benz cars using that oil with the extended (10K-15K mile) change interval with zero issues. Several of my cars have gone over 200,000 miles.
But if you want the short of it:
ANY high mileage full synthetic 5w-30 oil will do great. Mobil 1? Sure. Amazon Basics? Hell yeah. Wal-Mart's Supertech? Send it.
I dropped some 0W-30 Mobil 1 this winter, and my sol with a d15b7 loved it. Made cold starts very smooth, and noticed no reasons not to continue running it.
I had consumption issues with Mobil-1 0W-40 in the W8, and Castrol/Valvoline 5W-40's showed signs of wear at higher mileage intervals when I ran a 10,000 OCI as recommended by VW.
