Hey fellow Jag'sters; ok, so I did some searching on this, but not much came up, so maybe there's not many, to any with this issue (although, I hope so, just to get a resolution)

But the title says it; I engage the button, & nothing happens; no LED, nothing showing on the cluster (I'm assuming it does bc it shows in my RRS ) no downshift when I'm sitting still & engage the button, so,,,, it notta work! Hahaha

Anyone else with this?..

 

Try a hard reset and see what happens.

- Disconnect both battery cables from battery
- Turn on ignition
- Turn off ignition
- Connect battery cables together
- Turn on ignition
- Turn off ignition
- Reconnect battery cables to battery
- Start the car
- Let it idle for about 10 Minutes

Thanks for the reply Don. Funny thing is, while I was typing the original post, I was sayin to myself, "I bet Don B is going to be the 1st to answer".

I was close in my thinking! Hahaha

In regard to the reply, I'm assuming that everything gets reset? & when you say, "connect the battery cables together", I don't know why, but that seems a bit scary to me!..

 

They are not connected to the battery so nothing to worry about. What your looking to do is drain the capacitors in any of the control units/modules in the car. Now of course you wouldn't take the negative or positive cables and touch them to third opposites while one is still connected to the battery. Perhaps this is what you were thinking?

 

Ha! Yeah, I guess that was what I was thinking in some manner. I got what you're saying though. I'll try it later & see what happens. Thanks again!..

 

Did it work?

 

Ha! *confession* I'm a bit leary on trying it [i don't know why] other then the fact nothing else is wrong, so i guess i don't wanna potentially bring other problems to the fold since Sport mode isn't something i need, but just want. (Make sense?) 😐

 

I understand completely......I've been there myself!

 

Really nothing to go wrong but if your uncomfortable with touching the battery cables together you can do this:

Disconnect positive and negative cables.
Turn ignition swith on, position 2.
Leave on for an hour (or so).
Reconnect both cables.

This will allow the capacitors to drain on their own.

 

I'll try it tonite... (the 1st way)

 

Unfortunately that didn't solve it...

 

It may not appear in the cluster (doesn't on S-Types) in which case that would just leave the other telltale - maybe it's blown?

 

It may be. I'm getting my front bushings replaced today, so I'll have them check into the Sport mode issue as well...

 

Ok,,,, so,,,, last night for the 1st time since I've had the car, I decided to give her a good "punch to the floor"!

JEEEZZZZ!!! After doing that, I'm like, "FARK SPORTS MODE"!!! Hahaha

Heck, who needs it when the car is that fast!?!? I'd hate to do that in an XJR or SuperV8. Wowwww!!!

Ok, I just had to get that out!..

 

does this reset also work on the X308?

 

Yes it does

 

thank you for future reference what all does the hard reset effect? Anything i might want to have handy? Radio codes startup procedures after the reset? Anything else?

 

No radio code will be needed , windows will need to be reset though
