Limp mode with no fault codes

[JustMeLel]

Hi guys i was hoping you could help me with some info on this issue i have been having lately.

One day after i made around 1000k plus km when i got onto the autobahn i did around 200 , and suddenly limp mode happenend , which it never happened before.

It completly cuts the turbo and some good amount of power but it only happens over 140 km/h , it is random because some days i hit 180 and it doesn't trigger limp mode.

I was thinking it could be some turbo issue.

One possibility is a failing battery. I suggest you get it professionally tested. Do not rely on a simple voltage reading to indicate the state of health of the battery, nor should you rely on its starting ability. If the battery proves to be in good condition we need to investigate other possibilities.

I had it tested a few months ago it was fine

In that case we need to find a way to diagnose the fault, which is going to be nearly impossible just on written descriptions. Perhaps the best way forward is to get a diagnosis on a different machine. Code readers differ greatly in their abilities.
