My daughter drives a 2010 1.6D 90,000 miles and her car cuts out at 2000 rpm. If the revs are gently increased to 2000 and held there the engine constantly misfires and runs very rough then if the accelerator is pressed a little further the engine runs perfectly with loads of power. There is no engine management light has come on as yet and I have used the Autocom diagnostics which shows no recorded faults. So far I have changed the fuel filter and cleaned the EGR valve (which was only slightly sooty). Has anyone else had this problem? Could it be as simple as a faulty accelerator pedal?
We can't wait for some suggestions and help.

might be injector ie the rail pressure rises the harder the engine is rev.d and would force the injector to fire normally as such, need to do a leak off test see whats being bypassed within the injectors, also a compression test needs doing. the piezo injectors if blocked or nozzle damages will cause miss and no codes, but live data run would should show which cylinder etc,

I had a similar fault in my Astra diesel misfire between 1700 & 1900rpm turned out to be a bad injector. Learnt my lesson about buying exchange parts from Euro Car Parts on that one. If you need an injector use a diesel specialist to replace or rebuild it. I ended up paying for 9 injectors and only go a refund on one.
