The elusive on again -off again Sport Mode
I was embarrassed to share this sometimes works , some times doesn't work Sport Mode on my 2005 X100 XKR vert tale. I got advice from change the switch below the J-Gate (didn't help) to the pull the contactors off the side of the ZF 6 speed and clean the contactors (didn't help) to change the associated computer module (didn't help and they took it back, less labor to the ignition harness wire contacts cleaning (didn't help).
You're all thinking it must be the ABS sprockets on the wheels then (first thing checked, didn't help). Nearing the end of my pride and about to ask the forum, I had the pleasure of watching my supercharger being removed and replaced to change a leaking coolant hose at the Jag dealer when I spoke to the Service Manager, Frank at 320 E. Fletcher Ave. Tampa , FL Jaguar Land Rover and told him about my mystery. He said maybe I should look at the ABS Rotors again. He was squeezing me in and did not have the time during the Grand Prix weekend to look.
Guess what? That rotor is press fit on the rotor. A severe pot hole can jar it enough to loosen it. If it slips, all manner of interesting messages present themselves. My favorite is the worry free TRANSMISSION FAULT" with an amber light as I try to add up the numbers guess on a new tranny. Sure enough, it was a slipping rotor. SN Barratt came through for 69.00 usd on a 272.00 Jaguar USA part for the new ABS Rotor. It looks like Jaguar Merriam at 352.00 will be the supplier of the new lh rear hub, since Field's Jag back in my Wisconsin homebase is at 506.00 for the hub.
If your s mode is intermittent, check rotation of the tires, excuse me tyres to you Brits, and if you hear a bearing beginning to go out sound, it could be the ABS rotor.

The vibration I experienced was similar to a wet rotor warp being sanded flat by the EBC reds. It was only braking at high speeds, when the DSC and ABS sensors come into play. Also, driving in a quiet fenced lane, I heard the faint rubbing sound like a early stage of a wheel bearing failure that suggested something was rubbing that ought not to be doing so. Hope this helps.

The sport mode button and the J-gate shifting are affected at the same time. Sport button LED turns off and the car will only shift as an automatic regardless of whatever gear I put it in.
Being an older post, I am curious what the result was? You mention it is high on the suspect list but no followup about whether or not this ended up being the problem and if it was resolved?
