Jaguar XK8 CD Changer E-01, NO DISC or Stuck
On the XK8 a changer showing E-01 rarely needs replacing: usually it's a jammed magazine, a corrupted disc inventory or dry gears. I'd free the magazine by hand, then reset with an empty magazine, then grease the mechanism — a refurbished or even new changer can fail the same way.

Safe to drive — only the discs are at stake
Forcing a stuck magazine out with the wrong tool can bend the trays, so go gently.
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.
A jammed magazine — release it by hand
A disc caught half-way between magazine and player blocks the magazine. The changer reports E-01 and won't eject, though nothing is broken.
E-01 appears suddenly and the green eject button does nothing. Earlier episodes may have cleared by pulling and refitting the magazine.
Ignition on, hold eject and slide a thin stiff strip — credit card, letter opener, a thin steel rule about 1/2 in wide — 4–5 in under the magazine, then push it towards the front of the car; or tap the changer firmly with a screwdriver handle. It may take a few tries.
Once the magazine is free — levered with a letter opener, a small screwdriver or a knife, or knocked loose with taps — the changer plays again. If a single disc is stuck rather than the magazine, a couple of fingers through the opening can reach it; failing that, the cover comes off and the disc comes out by hand.
The changer has lost track of its discs — reset it with an empty magazine
The changer keeps an inventory of each slot. When that list is corrupted it keeps throwing E-01 whatever you clean or replace.
E-01 keeps coming back: one disc plays, then the error. Cleaning and lubricating help only for a while.
Take every disc out, insert the empty magazine and select CD. Let it step through each slot until each reports NO DISC.
Then reload the discs — the reset cures a recurring E-01 where a new magazine doesn't.
Dry or loose parts in the mechanism
Grease dries, slides get dirty, small parts work loose — a set screw locking a small gear, the nut on the worm gear. The changer searches and gives up, reporting NO DISC with a full magazine.
NO DISC with six discs loaded while you hear the mechanism searching — so it has power. A disc that never spins can't be read either — the fault may still be simple once the cover is off.
Take it out (boot trim off, a few bolts). Look for a gear locked by its set screw or a loose worm-gear nut.
Clean the slides with alcohol, lightly grease slides and gears, loosen a locked gear's set screw until it clicks free, and re-tighten the worm-gear nut with thread-locker. Tapping the small drive motor can help too.
Home-burned discs and the wrong magazine
The original changer is fussy. Burned discs differ slightly in thickness and stick; two styles of magazine exist with different latches, and the wrong one jams more often.
Errors that follow certain discs, or started with a second-hand magazine. Check too that no disc is loaded upside down — the changer won't recognise it.
Load only pressed retail discs for a week. Compare the latches under the magazine with a known original.
Worth trying: pressed discs only, and a genuine magazine in place of the wrong one — that can clear an -01 error. Magazines from 4.0-litre cars generally interchange: XK8 1998–2002 and XJ8 1998–2003.
A weak battery
The mechanism needs a solid supply to load and eject. On a tired battery it tries, fails and stops.
The changer tries to load for a few seconds and gives up; the magazine won't come out. The battery is original or old.
Try a booster pack first. Disconnecting the battery for about 30 seconds can pop the magazine out on reconnection.
Worth trying: replace an old battery, even one that seems healthy.
A dirty or worn laser
Discs load but can't be read, so each is rejected in turn.
NO DISC or skipping within discs, with the mechanism moving normally.
Try a lens-cleaning disc first. If that fails, open the changer and clean the lens with a long swab and alcohol.
Cleaning may be enough. If not, a rebuilt or used changer is the realistic answer — from a breaker or online; a rebuild runs about $270. A worn mechanism that skips within discs is cured by a replacement unit.
Discs skip on rough roads: a loose mechanism or a tired plug
The mechanism floats on rubber bushings inside the case, and the factory changer has no anti-skip memory, so some skipping on bumps is built in. Aged bushings or a poor contact at its plug make it worse.
Skipping on rough roads, with the discs reading normally on smooth ones.
Pull the side carpet at the rear of the boot and feel whether the mechanism is loose in its case.
Worth trying: contact cleaner in the changer's plug and socket helps for a while. For skip-free music, a player through a cassette adapter.

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.
Hold eject and slide a strip under the magazine
Ignition on. A credit card or thin steel rule 4–5 in under the magazine while holding the green button, pushed towards the front; or firm taps with a screwdriver handle.
freeReset the inventory with an empty magazine
All discs out, empty magazine in, select CD, let it report NO DISC for every slot. Then reload.
freePressed discs only, and an original magazine
Rule out the media before the machine. Discs the right way up, and a magazine from a 4.0-litre car.
freeCheck the battery
A booster pack or a brief disconnect is a free test — keep the radio code to hand.
freeChanger out: clean, grease, look for loose parts
It lives on the right-hand side of the boot, under the side carpet, racked together with the amplifier. Grease gears and slides, free any locked gear, tighten the worm-gear nut.
free, an afternoonOnly then a used changer
It's powered through the lead from the head unit, with no separate fuse; to isolate it, follow its short lead to the connector behind the boot trim. Don't plug in a generic Alpine changer as a test — it can blank the whole sound system until the original goes back.
