Volkswagen Touareg 2.5 TDI Stage 1 Remap
On Volkswagen Touareg 2.5 TDI diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. 2.5 TDI engines with 163–174 bhp reach 204 bhp with a Stage 1 remap; the largest gain is +41 bhp (2.5 TDI 163hp). Pick your version in the table below.

About the VW 2.5 TDI (Transporter, Crafter, Touareg)
The five-cylinder 2.5 TDI was used in the Transporter T5, Crafter and first-generation Touareg. Designed for work under load, it benefits from a careful calibration both in pulling power and in fuel efficiency.
How a Stage 1 remap works on the Volkswagen Touareg 2.5 TDI
Stage 1 re-tunes the torque limiter and boost maps with heavy-load use in mind. Hill climbs and overtaking with a full van improve clearly, and holding the same speed at lower revs can help consumption.
Pre-remap checklist
- Camshaft and unit injector wear, the known weak point of this engine.
- Turbo and exhaust manifold crack check.
- Cooling system and oil pressure.
