99 c230k cutting at 140km/h (80mph)
 

My couzin's benz is cutting at 140km/h.
He scanned the car and it said p-flow valve needs to be changed. (I find it weird it says p-flow but wtv)

He claims when he hits around 140km/h the rpms go up to 6000rpm, and it cuts. (regardless of gear he is in)

Does anyone know the problem?

I have a P flow problem myself, and the doctors can't fix it?:D Sorry but I can't help you, I don't even know what a P flow valve or wtc are?

pressure flow maybe.

but at 6000 rpm, the transmission is still engaged. it still should accelerate.
