Since couple of last weeks I have been experiencing strange behaviour of my car – loss of turbo in the morning – probably limp mode.
I am getting 2 fault codes 17705 and 17545. When engine was turned off / on – turbo was immediately back.

It only happened sometimes on morning (temp between 2-5 °C) when I drove to the work (8am) – basically after start I had limp mode – 5psi, when I turned engine off/on turbo was back;

It is strange because it never ever happened when I came back from the work at 5pm.

Also car never gone into limp mode when pushed hard.

Car is AUDI TT 1.8T 225 - remapped.

Any idea really appreciated!

Thank you,
