Seems there's lots about already, but every car's a little different it seems.
My Modus is 5 years old / 66k miles and up until recently I was the happiest person in the world with this car...
Driving to Germany, I suddenly had a 'check emissions' fault - car felt fine though.
However, local garage on first attempt just deleted error message - it came back. Second attempt replaced glow plugs (2 very bad apparently) - it came back. Third attempt replaced
valve - and guess what...
Back in UK they followed the procedure - on first attempt deleted error message - it came back. Then cleaned
pipes (clogged up apparently) - and it's come back!
But also now it comes up with 'check injection' every now and again. I can now actually feel a slight loss of power in acceleration, but nothing major....
The only other two things to mention - I had the battery replaced 2 months ago.
Just before I had the first error message I filled up with some kind of 'performance diesel'.
Maddening - but anybody any ideas...?
Have paid £700 already...
