A6 1.9tdi turbo runs ok when engine cold.

Hi everyone, I've owned my A6 Avant 1.9tdi se for 4 months now.After 1 week noticed no power at speeds of around 80. A 19 test and tune diagnosed air mass flow meter and changed same with reconditioned one.All seemed ok until I noticed that the kick in the back feeling is not there, only when running from cold. When warm the engine revs ok but there is no power.
I love the car to bits. But please anyone what is the cure?

Hello and welcome.

1.9tdi wont give a kick in a heavy car like the a6, it will also be naturally slower when warm because of heat in the engine bay.

also do not rev when cold when oil is cold it can not lubricate the turbo and will lead to premature failure
