Well, I knew it would happen sooner or later- of course with my luck, it was sooner. (2002 XJ8 76,000)

So, I am on my way tomorrow to AutoZone to buy the code reader (Innova2 F). I suspect it is going to be a very used item.

The question I have is this- is this light most likely a fairly minor thing or could it be a catastrophic engine-about-to blow? Since I have never seen other dash lights, I am not sure if other, worse warnings will come on.
The engine is purring like a kitten and the drive is as smooth as silk, nothing out of the ordinary at all. The only odd thing I noticed was the check gas cap light came on almost at the same time as the engine light, then, after a couple minuets, went off.

Would you feel safe to drive this car 45 miles to work? I kinda' do not feel like having my car go to pieces on the interstate. I will get the code reader at lunch.

Sure is hard to locate a shop willing to work on Jaguars. I have been calling around, no luck. Figure I will need one before long. I saw the check list of "to do" things for this model. Guess I better be ready.
Thanks!

 

Cheap tool with live data is best bet, such as elm327. Could just be the gas cap. I'd drive, sure. Most codes are faults but not even vaguely disastrous.
