    Drove to and around Belfast from Dublin and towards the end get engine warning and no limp mode but not that powerful

    He connected it up and wiped the error and said EGR filter or the like (hard with low speaking and accent), thankfully good enough to charge 20 pounds

    Says if giving me trouble to take out the DPF and when I said NCT checked it, he said some can cut it and stich it up so still "there"

    Said I need to drive it harder in higher revs

    Has anyone THE solution as becoming a money pit but don't want to sell as secondhand market crap and I've fixed a lot of long-term items (2010 so SOME items will go I know)

    Ford focus 1.6 TCDI

    Thanks for help etc

    Go to halfords, buy stp diesel cleaner - ask the staff - puy in your fuel tank before or after putting fuel in. And drive it normally, or for best result blast it up the motorway sunday morning, or drive it at 3rd or 4th gear 3k rpm for 10 minutes.

    I would put a blanking plate on the EGR valve and get it mapped out from the ECU to prevent a fault being logged.

    Or, what I did with my diesel Astra was just fit the blanking plate and get a cheap scanner to delete the fault warning light before driving to the NCT centre. Worked great for years whilst I owned the car, and I believe it is still going strong with the new owner.

    Make sure to give it a decent drive on the motorway at higher rpm to get the DPF to regenerate regularly too.

    The dpf and egr valve work in conjunction I believe. You can delete the dpf and leave the egr, but you can't delete the egr and leave the dpf. It won't work properly.

    Well, you can and I did. 😉

    Whilst they are not mutually exclusive, they both serve different purposes ultimately.
