Volkswagen Car Diagnostics
Volkswagen vehicles (Golf, Passat, Polo, Tiguan and others) support the OBD2/EOBD standard and can be read with AutoMulti via an ELM327-based adapter. VW's TSI/TDI engines commonly show carbon-buildup and timing-related codes.
Where is the OBD2 port?
The OBD2 port is usually under the steering wheel, near the fuse box or in the lower driver-side panel; on some models it's hidden behind a small cover.

Coding and hidden features
The VW/VAG group has the richest ecosystem for software 'hidden feature' activation: needle sweep, daytime running lights (DRL), mirror fold, coming/leaving-home lights, video-in-motion and more can be coded. Approved coding is on AutoMulti's roadmap.
