I own a 05 plate focus - 1.6 TDCI
It has done 80k miles and had its last service in June
For the past few weeks I keep getting the red warning light come on and the display reads "engine systems fault"
As I was on holiday my mum took it it the garage and two fault codes were returned
P2585 and P2458
The mechanic said it was down to the fuel additive regeneration container being empty.
What I wanted to know was is this something that should have been checked at the service, and also since it was empty is there any damage that could have been caused to the car?
Thank you in advance
