Audi SQ7 (2016) 4.0 TDI V8 429 hp — premium diesel engine of the passenger segment of the Volkswagen Group (VAG) group (Германия, 1909). A diesel built in 2016 — the Tricore ECU era; OBD flash works on most production revisions.
Audi's petrol range is badged TFSI, and the diesel range TDI. quattro is Audi's signature all-wheel-drive system, introduced in 1980. The four rings in the Audi logo are a legacy of the 1932 Auto Union merger of Audi, Horch, DKW and Wanderer. Audi S models with a diesel engine use an electrically driven compressor to eliminate turbo lag. The factory calibration of Audi diesels is conservative, leaving headroom for Stage 1. Audi is the originator of mass-market TDI passenger-car engines in Europe.
Within the VAG group, ECUs are standardised, so a single file often fits a dozen models across Audi/VW/Skoda/Seat. APR and Revo are the leading tuning brands for Audi, right up to Stage 1+. On Audi, Stage 1 usually fits within the standard turnaround time. RS engines are a proven base once supporting hardware is added (downpipe, intake and intercooler). Top-tier Audi Sport engines (RS models) sit at Audi's power ceiling; the gain is significant. APR and Revo are the leading tuning brands for top Audi engines. A Bench read is standard procedure on modern RS engines.
