Ford 1.5L Diesel: ECU update solves excessive smoke issue

Ford 1.5L diesel engine's excessive smoke issue has an easy fix.

The Ford 1.5L diesel engine is said to emit excessive black smoke under heavy acceleration. It is a very common problem that most owners of the EcoSport diesel face. But, there seems to be an easy fix to this.

A 2019 Freestyle had a similar issue of excessive dense black smoke at over 2,000 rpm. The owner of the vehicle registered a complaint with Ford, following which the car was picked up by the local dealership.

The issue was resolved with just an ECU remap. The owner reports that there is visibly no smoke at moderate rpms. At engine speeds in excess of 3,000 rpm, less dense smoke was observed. The owner also noted that there was no trace of soot left on the garage door after accelerating.
