How does this differ from the other Laguna entries?
This covers the second generation specifically. Our history records the model under several designations, so check them all.
How does the 1.9 dCi respond?
It gains considerable mid-range flexibility from a measured map. It is a robust and well-documented engine.
Is a remap worthwhile on a car of this age?
It depends on engine condition. A well-maintained dCi responds well, but remapping does not compensate for wear.
