Mysterious Red Light
Driving home from work I last night, I hit a bump on the Interstate and thought I saw a red light flicker around the thermostat gauge. I hit another bump about a mile from the house, and thought I saw it again. It has been a long day and i was tired, sure I wasn't sure.
But coming home from work again, I hit those same two bumps again and it didthe red light! It doesn't stay on...just flashes when I hit those bumps.
What would the light be?

RE: Mysterious Red Light
Honestly Jamey..I don't know what it could be..Look at your OM and see if you can find the corresponding light on the Instrument display per the book....May give one of the Jag dudes here something to go on..Could be a lowCoolant level sensor if the reservoir tank is kinda low..

RE: Mysterious Red Light
It's possible that it could be a loose sensor (ie. trunk open) that just flashes when you hit bumps.
Or, it could be the early signs of a Gearbox Fault failure. Chances are that if it flashes (even for a second) it might be triggering some codes in the system and that would be the only surefire way to know. Your dealer can tell you if any have registered and what they mean.
I actually had this happen to me a while back and it occurred just a few months prior to receiving a Gearbox Fault failure that required a replacement transmission.
I've also heard talks on other forums of a loose wiring harness that could also be the problem and may go overlooked. Either way it sounds like your best bet is to bring it to the dealer.

RE: Mysterious Red Light
Well you can buy a code reader but theres no guarantee that it will show results (or accurate ones) in the case that something is loose.
Not sure what else you can do but I just want to warn you that if it is a genuine Gearbox Fault alert you'll want to make that 4 hour trip to the dealer real fast.
Someone else here might have some more suggestions.

RE: Mysterious Red Light
This exact same thing happened to me prior to getting Gearbox Failure lights. I figured it was something loose as well but the dealer got suspicious when I told them about a red light flashing. Turned out they were right and I got a permanent Gearbox Failure about a month and a half later. They replaced the transmission and I didn't get any more flashes.
Anyway, from the little information he provided it's impossible to tell and like I said the only surefire way is to check the codes!
