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 Audi A6 C5 2.5 TDI 180hp
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.
This section is based on Prime Chiptuning workshop experience; the power and torque figures come from the catalogue measurement above.
