My 2006 Ford Focus 1.6 TDCi came up with an engine systems failure message today just coming off of a dual carriageway (70mph) accompanied by a red light next to the trip computer. I think it went into limp mode (severly reduced power, unwiling to rev much), so not good when you live at the top of a hill! Two other times when starting the car it has briefly displayed an error message (once it said "steering assist failure", and yesterday it came up with the same engine systems failure message"). Both times I have restarted the car and it disappeared.
The car is a 2006 on an 06 plate, and has currently done 73500 miles. I bought it last may at 65000 miles, and it had a service just before I bought it. As it had just turned 6 years old/65000 miles, I'm presuming the DPF would have been changed then?
Does anyone have any idea what's wrong?
Thanks in advance,
