How does this differ from the other X-Class entries?
Our history records the model under several designations. Each group covers different units, so it is worth checking all of them.
Can I disable the AdBlue system?
Not on public roads: regulations require emissions systems to be operational. These files exist for specific applications; ask us before ordering anything.
Will I notice a difference when towing?
That is exactly where it shows: the extra mid-range torque reduces the need to change down on gradients with a trailer or a full bed.
