Hi, So I own a 2019 Golf r which means I unfortunately have the GPF filter. I've been looking around online and seen an example of a car with a backbox delete and i'd like to get it done myself as it's a fairly cheap option. What are the negatives of doing something like this when it comes to warranty ? And also will they be weird with me at VW when I come to take it in for my free service? Any info appreciated, cheers
