Cheapo blue -20 from Walmart. I don't use Rain-X... it screwed my sensor up in my MKV as VW uses electrodes in the reservoir to sense the level instead of a level float. The Rain-x coats the electrodes causing them to think the reservoir is always empty.
Cheap Blue or you can order VW concentrated and dilute with distilled water in summer time. I think you can find on ebay or Amazon.
The VW stuff does smell good. Like the original tank full that was in car on delivery.
