hi everyone my vw jetta has been losing power for the last week,,, it only happens when i get up to a certain speed of about 110 kph,, it like the turbo stops working but there isnt any smoke etc.. if i turn off the engine and turn it back on it works fine until i get back upto that speed.. the engine managment light came on today so i brought it to my friend house who has a basic diagnostic kit.. the codes that showed up are 05658, 05659, 05661 and 00564

he was able to erase them however the car is still acting in the same manner..

is there anybody who knows what it may be. and how to remedy it

The car is going into limp home mode and turning off the engine resets it .
The father had a 01 passat which did similar .
They were well known for mass air flow sensor to give trouble.
If you disconnect the mass airflow sensor and the issue disappears the MAF needs replacing
