I have a 2001 XKR convertible. I was putzing around in the car today and found a Jaguar sticker stating that the car has been reflashed/approved by Jaguar. Is anyone familiar with this ? Ive owned the car for less than a year.

 

What "reflash" was performed? If you provide the string of letters and numbers referenced on your paperwork, someone here will be able to tell you exactly what was done....

 

I just checked the sticker and all it has is factory authorized and reflash written on it. I have no paperwork on the reflash.

 

Reflash means the software of either one (or more) control modules or the ECU itself was updated. There are a number of scenarios

• An updated purge valve was installed and the new version requires an accompanying code change
• A control module was replaced and ran a newer version as compared to the original module. The ECU had to be told to trust it (VCATS logic)
• The ECU had to be replaced and reprogrammed for your country and for the modules actually installed in your car.
• A prior owner complained about something and the ECU was updated to run a later version
• A prior owner installed the cabin air filter and an accompanying code change was done to up the A/C fan air flow
• (less sure of this one) The shifter light module was replaced with the later reman model requiring updated CAN messages

I am sure there are others...

 

Thanks.
The reflash was done in 2002 so it wasn't long after the original owner bought the car.

 

Probably 303-49 or 303-53

 

That is what it probably is. The dates line up. Thank you.
