It's changing - manufacturers are definitely cracking down. This particular person did all of his own oil changes and kept good records with receipts of part purchases. Claim was ultimately denied due to insufficient evidence, but the dealer was able to workout a goodwill arrangement that covered most of the repair.The only issue I've ever heard was for the older 1.8T that VW had issues with sludging due to the small sump...VW wanted receipts but everything I read/heard said they just wanted to see oil changes...the type of oil wasn't so much of the issue.
