Loss of power at 70mph

[Perry1150]

Hi.
Wonder if anyone could advise or point me to a thread already underway.

I have a VW T6 2017 32. It’s an old AA van converted to abit of a day van/camper.
It’s got around 107000 miles on it.

So issues wise since I got it I have been ok really. I had an engine management light come on in May and then cancel when I stopped to explore.

Since then the van will not accelerate over 70mph. It performs fine through the gears and accelerates normally then at 70 it’s like it has a limiter on.

I’ve used Carista and there’s no alerts or warnings.

There’s no specific noises or any leaks from what I can see looking into the engine bay.

I feel like I’m about to start an expensive exploration.

Anyone had this problem before? If so any ways that I can diagnose visually and remedy myself before sending her into a professional??

Thanks so much

Ex-fleet vans do tend to have a limiter on

it has driven over 70mph before.
Can this limiter come back on if there is a fault that resets itself?

Is there a way of checking if a limiter is in place through Carista??
