About This Tune

3.0 TDI. Stage 1 + TCU.

The Audi A5 3.0 TDI is one of the most capable V6 diesels in the VAG range, effortlessly quick and beautifully refined, yet left deliberately conservative from the factory. With a custom Stage 1 ECU calibration combined with a ZF8 TCU gearbox tune from DC Remapping, the platform is finally dialled in properly.

This A5 arrived producing 291bhp and 619Nm, and after our Stage 1 custom dyno calibration combined with the TCU tune it left delivering a strong 352bhp and 749Nm. The result is huge mid-range torque, sharper throttle response and effortless acceleration that makes the car feel significantly more responsive in everyday driving.

All work was carried out live on our dyno, with full health checks and detailed data logging throughout the process. No generic files, no shortcuts, just precision VAG tuning done properly, with the ECU and TCU developed together as one cohesive package.

Gearbox Tuning

ZF8 TCU Calibration.

The ZF 8-speed Tiptronic fitted to the A5 3.0 TDI quattro is one of the finest automatics in the industry, strong, smooth and quick. From the factory, however, it is calibrated conservatively, holding back shift speed and torque to keep things gentle.

Our TCU calibration unlocks the full capability of the ZF8. Shift speeds become noticeably quicker, torque management is optimised and gear logic under load is far more decisive, letting the drivetrain safely and fully utilise the increased output from the Stage 1 ECU tune.

The result is an A5 that feels cohesive and genuinely rapid, with the engine and gearbox working as one. Fully reversible at any time.

Sharper Shift ResponseNoticeably faster shifts in Sport mode. The gearbox reacts immediately to throttle inputs rather than pausing to decide.
Raised Torque LimitsFactory TCU torque limiters increased to correctly handle the Stage 1 engine output without unnecessary intervention.
Optimised Shift PointsSmarter shift logic across Comfort, Sport and Manual modes tailored specifically to the A5 3.0 TDI.
Smooth at All SpeedsRefinement retained in Comfort mode. The tune improves performance without compromising the A5's everyday usability.
Fully ReversibleFactory gearbox settings can be restored at any time. Your ZF8 TCU is not permanently altered.

This is not my first time with DC Remapping and every time I've had a csr to remap, the owner has not only out done himself, but has made sure the maps are safe, reliable and plenty of power! My first Audi A5 3.0tdi did 60k on stage 1 and never had any engine issues from it. …

FAQs

Audi A5 Tuning Questions

How much power will a Stage 1 remap add to my Audi A5?

Our Stage 1 maps are custom-built on our in-house 4WD dyno and tailored to your exact Audi A5, never a generic off-the-shelf file. You'll see a substantial, fully dyno-proven gain in both power and torque; the headline figures for this platform are shown at the top of this page. Because every map is refined over multiple runs, the results are realistic, repeatable and safe.

Is remapping my Audi A5 safe and reliable?

Yes. We tune strictly within the safe mechanical limits of your Audi A5's engine and gearbox, monitoring temperatures, pressures and torque loads across multiple dyno pulls. We've spent 15+ years tuning these platforms, so our maps prioritise long-term reliability alongside performance.

Will a remap affect my warranty or insurance?

A remap is an aftermarket modification, so it's the owner's responsibility to declare it to their insurer. Our maps are fully reversible, we can return the Audi A5 to its factory software whenever you need, for example before a main-dealer visit.

Is the remap reversible?

Completely. It is fully reversible: your Audi A5 can be put back to its factory software at any time.

Will tuning improve my Audi A5's fuel economy?

We tune for performance, not fuel economy, so we don’t promise or guarantee any MPG saving. How much fuel the car uses comes down mostly to how it’s driven, and using the extra performance will use more.

How long does it take, and do you tune on a dyno?

Most Stage 1 tunes are completed within a few hours; allow up to a day for combined ECU and gearbox work. Every Audi A5 is mapped on our in-house 4WD dyno in Warrington, never on the road, so the result is measured and consistent. You're welcome to relax in our customer waiting area while we work.
