Welcome to the forum oldtimer69,
Putting it back on is optional but if you want to know why the CEL is on, putting a scantool on is essential. If you do, then post the codes here for advice on possible causes.
When you get a minute, please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some info about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

"P0455: EVAP system leak detected – large"
Causes:
Fuel cap off
Fuel cap seal defective / missing
EVAP system leak (canister damage, pipework damage)
EVAP Canister purge valve to engine purge pipe: blocked, leaking, disconnected
EVAP Canister purge valve failure (stuck closed)
EVAP Canister close valve failure (stuck open)
Fuel tank leak
The front side of the gas tank has a number of emissions-related components (canisters, hoses, etc.) in the same general neighborhood as the muffler(s). Might be worth revisiting...
