VW T5.1 (Euro 5) 2.0 CR TDI Engines

VW Transporter T5 Remapping / Tuning

The T5.1 comes with a 2.0 common rail diesel (CR) engine available in 84, 102, 115, 140, and 180 bhp. The 84, 102, 115, and 140 bhp models are mechanically identical, differing mainly in their gearboxes. The 140 bhp models have either a 6-speed manual or DSG (automatic) gearbox, while the lower bhp variants have a 5-speed manual. All these models feature the Bosch EDC17CP20 engine control unit, which is ideal for tuning. Six-speed or DSG models handle up to 420 NM of torque, while five-speed models need torque capped below 350 NM, peaking smoothly around 3000 RPM. Improper tuning can lead to costly issues like clutch, flywheel, or gearbox failures. We have perfected our tuning process to ensure good power output and drivetrain safety, backed by hundreds of hours of software development. We've tuned over 500 Euro 5 T5.1s to industry-leading standards, with 100% customer satisfaction. Our reputation attracts customers nationwide, and many T5.1s we’ve tuned still run smoothly beyond 300,000 miles.


BITDI 180 BHP Models:

The BITDI 180 bhp variants require careful tuning due to their lower reliability compared to single turbo models. Common issues include particle filter clogging, EGR cooler failures, and low engine compression. Contact us for more information or research "CFCA Engine EGR cooler issues" before booking your BITDI model for tuning.
