    1.6 eHdi Hesitation / 'missing' - worse in higher gears

    My 1.6 eHdi has just starting playing up; feels like its missing, but as its a diesel I assume its a injector problem - Seems fine in 1st and 2nd, goes through the rev range reasonably well; 3rd feels a bit off around 2,500 rpm but 4th is worse at 1200+ rpm. Feels like your trying to go up hill at 25mph in 4th rather than 40mph on the flat.

    My first thought is a fuelling problem but I would of thought this would be across all gears and rpm ranges. There's no warning lights or messages, I won't be able to get it to a diagnostic until Monday... Any ideas / suggestions before then?

    What's the mileage on it and what sort of journeys do you do in it?

    At a guess it could be fuel issue but I think that would log a fault code and the EML light would come on or I'm thinking it's more likely to be a EGR valve issue.

        Not many miles under its belt.

        Do you use supermarket fuel or branded station?

          Branded (shell), has a fuel cleaner in it at the moment, halfway through the tank so far.

          Had a long run recently, so I would think that should rule out the dpf too... Read a bit on this forum about people having a similar problem and being told it was an active regeneration cycle causing it (doubt that's considered normal).

            DPF ? Particulate filter needs a good blasting?

              Was a thought, but I don't like the idea of that being a normal thing...

              Went back out last night when the traffic had died off to see if it was just a blip or still there. Was still the same felt rough in 3rd at 2400rpm, worse in 4th at 1600rpm... Felt close to a stall / fighting feel.

              You could push through it to higher revs, 5th was the same as 4th... So drove it for a while at high ish revs (a little above the normal gear change), after about 10/15 mins it seemed to improve. Drove this morning and its as normal now.

              Makes it sound like a dpf or blockage somewhere that cleared. Again though, don't like the idea that anyway normal for a DPF clearance...
