Jaguar XJ8 (X308) Radio Code, CODE or PLEASE WAIT
The code belongs to the radio, not the car — a code looked up by the car's details fails if the radio has been changed. I'd look for a code on the casing, or read the serial from its label. Many North American cars never ask for one.
How bad is it · Safe to drive
Safe to drive — only the radio is locked
Nothing else is affected. But a code prompt without any battery work, together with lost seat or mirror memories, means the supply dipped — test the battery.
Which one applies to yours depends on your symptoms, your model year and what has already been done to it.
Likely causes, most common first
Read the check cost before the odds: a free check that rules a cause out beats a likely guess that costs money.
The radio has been replaced — a code by the car's details won't fit
Dealers look codes up by the car, which gives the factory radio's code. If the radio has since been swapped, that code fits a radio that's gone.
A dealer or online code is refused with a beep; the car has had more than one owner.
Take the radio out — the console slope and control panel come off. Look for a code written on the casing; failing that, the serial on the label.
Use the code on the casing, or one generated from the serial's last five digits.
A North American car — the radio may not be coded at all
UK and European radios are always coded. Most US-market radios are set to North America, which asks for no code after power loss.
A US or Canadian car; no code on record; none in the handbooks.
If you must disconnect the battery, just do it and see — presets can survive intact. The region is a setting: hold AM/FM and Tape Eject together to enter setup, press 1 and check it reads US (Jaguar TSB 415-06); a radio set to Europe or Australia will want its code.
Nothing to fix. Keep any code you find — the radio can still decide it wants one.
The original radio — the code from the dealer or the serial
No backup battery: lose the permanent feed and it wants its four-digit code. For the factory radio, the car's details or the label serial give it.
CODE after a battery disconnect, on a radio never changed.
Look for a plastic code card in the handbook wallet and a number written under the bonnet.
A dealer, with proof of ownership, or Jaguar's customer line; with no records, the serial on the radio's label.
A code prompt with no battery work — the supply dipped
If battery voltage sags far enough, several modules reset at once, the radio included.
A code prompt after standing, with seat and mirror memories lost — mirrors tilted down, for example.
Get the code, then have the battery charged and tested.
Enter the genuine code — a guess can leave PLEASE WAIT for hours, eight for example. Replace the battery if the prompt returns.
The order to check them in
The point of the order is money: each step either rules a cause out or makes the next one worth doing. Green is free, amber costs a little, red is the one to arrive at last.
Don't guess
A wrong entry or an internet 'bypass' combination leads to PLEASE WAIT; pulling the battery won't clear it.

If unsure, go by the radio: code on the casing, serial on the label.

freeNext battery change: keep it powered
A booster pack or charger on the leads keeps the code; many smart chargers give nothing without a battery. Never swap it with the engine running.
