Range Rover TDV6 (L405) Remap Dorset

This guide is written for the Land Rover Range Rover with the TDV6 L405 (approx. 2012 to 2021). We do not drop a generic download. Your file is built around ECU family, gearbox, mileage and how the 4x4 is used on Dorset and Hampshire roads and tracks.

Earlier torque for hills, loads and dual carriageway work. Headline figures only matter after the hardware proves it can take them. That is why every appointment starts with diagnostics and a clear go or no-go decision.

• Earlier torque for hills, loads and dual carriageway work
• Pre-flash diagnostics with live data where useful
• Factory map backup on supported control units
• Custom in-house calibration for the TDV6 L405
• Mobile service across Dorset and Hampshire from £249

Land Rover and Range Rover remapping around Dorset is about torque for hills, towing and confident dual carriageway pace. 24Tuning maps common Ingenium diesels and selected petrols after confirming the vehicle is mechanically ready. Mobile coverage of Dorset and Hampshire starts from £249; call 01202 503 328 with your VIN era and gearbox details.

Discovery, Defender and Range Rover Sport owners often want quieter, stronger mid-range without unsettled air suspension behaviour or gearbox hunting. We build Stage 1 files that respect transfer case and torque converter limits, using Alientech, Autotuner, Dimsport and MagicMotorsport where protocols allow.

Off-road capability stays intact when the base map is honest. Dynocom 4WD dyno work suits these platforms when you want measured verification. Stock files are backed up, software warranty covers the file we supply, and we will not sell UK road-illegal emissions deletion as a remap package.

Engine notes we keep in mind

• Ingenium 2.0 diesel: core of modern Discovery Sport and Range Rover Evoque; Stage 1 for usable torque when DPF load is normal.
• Ingenium 3.0 six-cylinder diesel: strong towing platform; maps prioritise sustained pull and thermal composure.
• Older TDV6 and SDV6 units: still on local roads; readiness and service history guide whether mapping is appropriate.

• 4x4 and towing focused Stage 1 philosophy.
• Mobile Dorset and Hampshire appointments from £249.
• Factory backup retained before every supported write.
• Dynocom 4WD dyno available for measured before and after.

Use this table as a planning guide. Your TDV6 L405 will not match a brochure line for line, and that honesty is deliberate.

If you want measured proof on a suitable vehicle, ask about Dynocom 4WD rolling-road time. Many owners are happy with road manners alone after a clean flash and verify.

Owners running the Land Rover Range Rover between Bournemouth, Poole and Southampton often want stronger mid-range so overtakes and slip-road merges need fewer downshifts.

Towing and payload with the TDV6 L405 decide the file. Stage 1 is aimed at usable pull on Dorset hills, not peak vanity figures.

High-mileage Hampshire drivers sometimes ask for an economy-biased Range Rover calibration after we confirm the platform is healthy enough for either path.

Weekend users still benefit: a composed throttle map makes the Land Rover Range Rover feel sharper on A-roads without turning an SUV into a track toy.

4x4 remapping in Dorset suits Discovery, Defender, Hilux, Ranger and similar tools that face hills, wet tracks and weekend towing. 24Tuning builds torque-led Stage 1 files after checking the vehicle is healthy enough for extra load.

We keep the main Remap Bournemouth overview on the homepage. This page stays focused on the Range Rover TDV6 (L405) Remap Dorset search intent so you are not reading a generic county brochure.

Trust is saying no when software is the wrong tool. These are common Land Rover Range Rover realities we discuss before booking a flash:

• Ignored service history, wrong oil grade, or overdue fuel filter changes
• AdBlue crystallisation or NOx sensor faults that need hardware attention first
• Chronic short trips that never complete Range Rover DPF regenerations
• Existing EGR or intake soot related running faults on the TDV6 L405
• Worn injectors or a tired turbo that already struggle at stock power

If the scan raises a red flag, we would rather reschedule than force a map onto a sick TDV6 L405.

Diesel Stage 1 at 24Tuning starts with diagnostics, not a blind flash. We read fault codes, look at live fuel rail pressure, boost, EGT related indicators where available, and DPF differential pressure so we know the engine can accept a stronger calibration. Only then do we back up the factory map and write a custom file.

The aim is more mid-range torque for overtakes, towing and dual carriageway pace, with injector duty and smoke limited to sensible levels. Mobile appointments cover Dorset and Hampshire from £249. Call 01202 503 328 to book.

• Diagnostics and readiness checks before any write
• Factory map backup retained on supported ECUs
• Custom Stage 1 torque focus for UK roads
• Alientech, Autotuner, Dimsport and MagicMotorsport tooling

A remap cannot repair a clogged DPF, failing AdBlue dosing module or worn injectors. We explain that clearly. If regeneration behaviour or NOx control is already struggling, we recommend fixing the hardware first.

Healthy aftertreatment plus a refined Stage 1 is the combination that lasts. We will not sell UK road-illegal deletion as a substitute for proper repairs.

On the Land Rover Range Rover we apply that thinking to the TDV6 L405 specifically, including how you actually drive in Dorset and Hampshire.

• DPF load reviewed in live data where possible
• AdBlue system health discussed before mapping
• No deletion-as-fix sales pitch for UK roads
• 4 year software warranty plus 30 day money back (T&Cs apply) on the file we supply

A typical Land Rover Range Rover appointment is about getting the process right, not rushing a write.

1. Discuss typical load, towing and tyre setup before any calibration targets are set.
2. Inspect for leaks, faults and gearbox behaviour under light load.
3. Back up stock software and confirm ECU protocol with Alientech, Autotuner, Dimsport or MagicMotorsport.
4. Flash a torque-led Stage 1 suited to 4WD drivetrain limits.
5. Loaded road test where safe, then sign off with aftercare notes.

Tooling is chosen for the ECU in front of us: Alientech, Autotuner, Dimsport or MagicMotorsport as the protocol allows. You should leave knowing what changed and how to reach us if something feels off later.

Our remapping is built on experience and documented results. We show our working: scan results, backup confirmation, and a calibration rationale tied to the TDV6 L405 rather than a social media horsepower graphic.

• Professional flash platforms matched to the control unit
• Mobile coverage so the Range Rover does not need a wasted day off the road for a simple Stage 1
• Optional Dynocom 4WD dyno when numbers matter for development or proof
• 4 year software warranty plus 30 day money back (T&Cs apply) on the file we supply
• Clear talk on insurance declaration and MOT emissions for UK road vehicles

Stage 1 on a healthy Range Rover is intended for stock hardware within sensible margins. Declare modifications to your insurer. MOT emissions rules still apply for UK road use.

If your use case is towing or commercial duty cycles, tell us up front. Duty cycle changes how aggressive the map should be.

This page is for owners of the Land Rover Range Rover (TDV6 L405, approx. 2012 to 2021) who want a careful Stage 1 with diagnostics included. It is not for anyone hunting a cheap blind flash, or for UK road users seeking illegal emissions deletion.

Book a 4x4 Stage 1 from £249 with factory map backup included.. If you are still comparing platforms, read the related guides below and then book when the Range Rover is serviced and ready.

Stage 1 for the Range Rover starts from £249. Booking online usually takes a £50 deposit. Call 01202 503 328 if you want to talk through engine codes first.

Aftercare means you are not abandoned after the flash. If a dashboard light appears that relates to the work, contact us with the registration and a clear description. 4 year software warranty plus 30 day money back (T&Cs apply) covers the file we supplied when the vehicle remains in the supported configuration.
