There are several alternative methods to regenerate the DPF in a VW Golf, including driving the vehicle at high speeds or on a motorway for an extended period. This can increase exhaust temperatures and trigger the regeneration process. Additionally, some aftermarket products claim to improve DPF performance and reduce the need for regeneration.
Anyway, it pretty reliably starts the regeneration as soon as it hits 103% (and the van is warmed up). My 2012 works similarly. I bought it used over a year ago, and my DPF level would reach 112 to 116% and then start regeneration. It would regenerate "100%" down to 12 to 16%.
