I have just looked on the Forscan Forum site, and there is a fair amount of entries about coding for the 1.6TDCI (DV6), so it looks like Forscan can do it. The Seimens/VDO injectors on the Mk2 Focus 1.8TDCI apparently are not individually coded, so no factors need to be entered. The ECU just adjusts.
Ford Year: 2007. UK/Ireland Location: Cumbria. Posted March 26, 2013. Help required, I have a 2007 Focus 1.8 tdci. The car started on Saturday morning then cut out. An Engine Systems Fault message came up on the dash board. I continued to try and start the car without any success.Posted June 24, 2013. the flashing light can indicate an issue with the charging system the truth is diagnostics will have to be done really it can be glow plugs faulty wiring injector faults etc. Quote.
