Best DPF App Available

The Auto connect via Car play is a game changer! The app is the clearest, and easiest to use. With an option for a stand alone screen making monitoring DPF accurate and effortless.

Response from developer

Great to know that the CarPlay functionality is working for you. Thanks for the encouraging feedback. Plenty more fixes and new features to add.

The BEST DPF monitoring app!

Without a doubt the best DPF monitoring app available for VAG vehicles. I’ve tried several over the years, but DPF Companion is on another level. The interface is incredibly clean, intuitive, and easy to understand, even if you’re not particularly technical.

The standout feature for me is the countdown showing the estimated time until the next regeneration. It’s such a simple idea, but it makes planning journeys so much easier and takes all the guesswork out of DPF regens.

The app is reliable, packed with useful information, and clearly designed by someone who understands what drivers actually need.

HIGHLY RECOMMEND!
