How does the 1.9 JTD respond?
It is a well-documented common-rail engine that gains considerable mid-range flexibility, noticeable on a large estate.
What is the difference between the 8V and 16V versions?
They are two cylinder-head configurations of the same block, with different output ratings. Both are present in our catalogue.
Is a remap worthwhile on a car of this age?
It depends on engine condition. On a well-maintained example it responds well, but remapping does not compensate for wear.
