How does this differ from the main Laguna entry?
This covers the third generation specifically. Our history records the model under several designations, so it is worth checking both.
How does the 2.0 dCi respond?
It gains considerable mid-range flexibility from a measured map, which suits a mid-size saloon covering high mileage.
Which output levels do you cover?
The 130, 150, 175 and 180 hp versions of the 2.0 dCi are all present in our catalogue.
