Default Is there a rev limiter on my XF?

Hello
I just got my new XF R Sport 2.0 Diesel on a 16 plate, I was wondering is there a rev limiter to prevent over revving the car by accident on this model?

Many Thanks

I think you will find all cars have a rev limiter set into the ECU nowadays.

Not meaning to sound smart or clever but without access to the ECU the only practical way would be to find a nice empty straight stretch of road and floor it.
Caveat-All suggestions acted on are at the owners risk

Usually it's limited in P and N to 3K or so.

All modern Jags have an N or P rev limiter of either 3,000 or 4,000 rpm.
In Drive it varies depending on the motor and gearbox and software controlling them.
On the 2.0 Ingenium diesel I would guess the rev limiter is set at around 5,500 rpm, and as we know it's not much point revving a diesel much over 4,500 rpm.
