Audi A4 TDI Remap
The 2.0 TDI is a motorway workhorse, and a properly written file makes it a far more relaxed car to drive — more torque low down means fewer downshifts and, driven sensibly, better fuel economy.

Audi A4 TDI Remap FAQs
Will a remap improve my MPG?
On a steady motorway run, usually yes — a few MPG is typical because you need less throttle for the same speed. Driving style decides the rest.
Does it affect the DPF?
A correctly written file doesn't harm the DPF. If yours is already blocked we'll tell you before mapping.
How long does it take?
Around an hour on the driveway for an OBD job, three to four hours for a bench job at the workshop.
