Sport button on gearbox not working?

[paulb3190]

Good morning everyone,
I recently bought a 2004 XKR convertible and I love it. 60K miles with few owners and seemingly very well cared for.

However, the sport button on the gearbox is not working. The button itself works and clicks into either the up or down position but when pressed nothing happens.
I know there's probably a number of different things it can be but I'd be interested to hear from anyone who's experienced the same issue and to know what was causing it for them.

It's also very nice to be back in a Jaguar. I haven't had one for the last 10 years since selling my 1986 XJ6 4.2.
I loved that car too and foolishly sold it in a moment of madness.

Thanks for any suggestions or assistance.

Welcome to the club, Paul.

Having a s type 2.7 diesel I find that when using the S button it does give an extra boost when accelerating. However, when cruising it makes little difference other than keeping the engine revs a little higher.

Have you noticed any difference in the engine revs when you press the button?  An increase in revs tells you that it is working.

Regards,

Peter.
