Is a remap worthwhile on a car of this age?
It depends on engine condition. A well-maintained HDi responds well to a measured map, but remapping does not compensate for wear.
What does the 2.0 HDi gain?
Mainly mid-range torque, which suits a large comfortable saloon. It makes overtaking easier and reduces downshifting when loaded.
Do you work with Siemens SID ECUs?
Yes, the SID803, SID803A and SID201 are common on this model and we cover them comprehensively.
