Hi again -
What is the mileage - ?

Hi again..
Thank you for that info.. I need to get as much info as I can you understand without being able to see it / test it.
-- Given all that you have said and described re the fault you have, the most likely issue here is a partially clogging injector -or, sticking pintles on one or more of the injectors. Very often this will show up after a service several weeks or so later --
Given too there are no fault codes or even an engine system fault light showing - this tends to rule most else out - certainly any components etc.. so again, its looking like the above.
Too - the mileage is about right for this sort of issue on some - so what I would suggest you do as it all adds up is - renew the fuel filter - regardless of if it was changed on the recent service.
At the same time, obtain a couple of cans / bottles of a good make of Diesel injector / system cleaner..
On fitting the new filter - fill that with Diesel inj cleaner -and then fit it.. Put the rest of the two cans in the tank - so it will work as you drive.
WIth having filled the fuel filter with cleaner it will put a nice virtually undiluted mix straight through the injectors - cleaning / freeing the injectors internally and cleaning the pintles as above.
This is often a good idea done on every other service or so on a diesel to prevent just the same problems as you have arising but most don't do it -- it can prevent what you have - and make for long lasting of the parts.
In your situation, it is the best thing you can do short of having the system professionally seen to - ultrasonic cleaning etc and very often will ward off you ever having to do that , saving a costly job.
This should restore your performance and correct your faults. Again , it will work as soon as you start up - and as you drive -as its in the tank - so give it time to work as well.. that will vary depending on your use / mileage.
IF the problem should arise again - rather than fault code testing ( as there is nothing wrong on those area ) - you would then be best to have the car to a Diesel Specialist who can test the performance of the fuel system / injection pump and so on and would find any other fault that way. But this is certainly worth a go - the best / cost effective way forward as its not so bad at the moment to get this sorted.
Let me know how you go..and / or let me know if you need anything further on this..
