Log in as a professionalFrequently asked questions
Is a remap worthwhile on a large MPV?
Yes, especially if the vehicle is regularly full. The extra mid-range torque is most noticeable with a full load or on gradients.
How does the 3.0 CDI V6 respond?
Very well. In a vehicle of this size and weight, the extra mid-range torque means noticeably fewer downshifts under load.
Does it affect the 4MATIC system?
No. The work is done on the engine ECU and does not alter the operation of the all-wheel-drive system.
