my td6 has a annoying habit of being powerless when first started but gets better as the car warms up, i have just put a new maf on which has stopped the codes coming up, any advice please

Get a diagnosis. Not all error show on the dash.

How long does it need to warm up to be respectable?

Has the fuel filter been changed recently?

no faults on machine and its ok after about 10 minutes,fuel/oil/air filters just done and engine and gearbox oil changed to, fingers crosses i may off fixed it today, took egr valve off and it was full off carbon and seized up, i will see if it better in the morning but it does seem to go better now only a 30 minute job to
