Audi SQ5 remap

3.0-litre V6, dyno-verified at our Eccles facility. The SQ5 has been sold with two very different engines under the same badge, and knowing which one is in front of us before we touch the ECU matters. Call 0161 302 5117 to discuss your car, or see the full range of Audi remapping we cover.

The SQ5's V6, by generation

The SQ5 has historically been UK-dominant as a 3.0-litre V6 TDI diesel, the engine most SQ5s on British roads actually carry, sold continuously since 2017. From 2021, Audi added a 3.0-litre V6 TFSI petrol alongside it, rather than replacing the diesel outright, so both generations of engine can be found on UK roads from that point on. The two are different engines with different remap characteristics entirely, and treating them as interchangeable is exactly the kind of shortcut that produces a bad map. Quattro is standard across the SQ5 range regardless of which engine is fitted.

. What is consistent across both generations is that the factory calibration is set conservatively for the same reason it always is on a car sold across multiple markets and fuel qualities. There is real headroom above it, and finding it properly means knowing which engine is actually in the car in front of us.

Why SQ5 remapping needs a specialist

Getting the TDI and TFSI generations confused is the single easiest mistake to make on this platform, and it is one we do not make. Samuel Gunnell confirms the exact engine and generation before any work starts, because a V6 diesel and a V6 petrol calibration are not the same job wearing the same badge. Audi does not have a remote tuning app on this site. The SQ5 is remapped in person via Kess3 and CMD at Eccles, with the ECU read directly rather than a generic file pushed to it.

That in-person approach matters more on the SQ5 than on most single-engine platforms, because a diesel V6 tune applied by mistake to what turns out to be the petrol generation, or vice versa, is not a small error. Confirming the exact car in front of us before opening a session is a standard part of the process, not an afterthought.

Every service available on the SQ5

Stage 1 applies across both SQ5 generations, tailored to whichever engine your car actually carries. Stage 2 is available on the TFSI where supporting hardware is fitted; the diesel generation has narrower headroom and we will advise honestly on what is realistic. An economy remap is a genuinely strong option on the TDI SQ5 in particular, given how many are used for serious motorway mileage rather than outright performance. We remap the automatic gearbox alongside the engine, and a standalone rolling road session is available for a baseline pull without a full remap. Every option here is discussed against your car's actual generation and mileage, not offered as a blanket package.

Automatic gearbox remapping

The SQ5's eight-speed automatic is remapped alongside the engine as a combined service. Shift speed and shift points are adjusted so the transmission suits the power the engine now makes, rather than the factory setting calibrated for the standard output.

Frequently asked questions

Is Stage 2 available on the SQ5?
On the TFSI generation, yes, where supporting hardware is fitted. The TDI generation has narrower headroom for a Stage 2 calibration, and we will tell you honestly what is realistic for your specific car.
Do you remap the automatic gearbox alongside the engine?
Yes, as a combined service. Shift speed and shift points are adjusted to suit the engine's new output.
How long does an SQ5 remap take?
A standard Stage 1 session typically takes a few hours at Eccles, covering the baseline pull, calibration and verification runs.
Will the remap affect quattro or the SQ5's driving modes?
No. The remap adjusts engine output, not the quattro system's mechanical operation or the car's factory drive modes.
Do you cover both the TDI and TFSI versions of the SQ5?
Yes. We confirm exactly which engine and generation your SQ5 has before booking, since the two require a genuinely different approach.
