This is almost always whitelisting. On a server that isn’t whitelisted the vehicles spawn and stay in the world, but the engine is switched off again every time someone tries to start it. That is by design.
  1. Open the dated whitelist log $profile:\CZAutoz_Whitelist_YYYY-MM-DD.log on your server and find the vehicle’s RESULT line.
  2. NOT REGISTERED — that IP and port aren’t on the mod’s whitelist. The line shows the exact IP and port checked: if the port is wrong, fix the -port in your launch parameters; otherwise register the server in #ip-whitelisting.
  3. PORT NOT READABLE — the server’s -port launch parameter couldn’t be read. Add it, then restart.
  4. COULD NOT VERIFY (NETWORK) or LICENCE NOT RE-CONFIRMED FOR 24 HOURS — the server can’t reach us. Ask your host to allow outbound traffic to czautoz.co.uk, and the check will pass on its next attempt.
  5. SERVER CLOCK OUT BY … SECONDS — the server’s clock is wrong. Turn on automatic time sync (NTP) on the host.
Every result and what it means is listed on the Whitelisting page.Once you’ve whitelisted, you don’t need to restart — a vehicle that failed its check tries again the next time someone turns the key, so just hop in and start the car. The check also repeats on its own, and a restart forces a fresh one.
Make sure you’re on the right version for your game: on DayZ 1.30 you need v2.9 or later (see the Vehicles Changelog) — every vehicle is on the 1.30 vehicle system.Separately, on versions before v2.7 some vehicles showed only part of their rear cluster — brake/reverse/tail segments on the boot lid or tailgate stayed dark for other players (the Urus’s brake lights were invisible entirely). The Planted Update (v2.7) fixed the full cluster on every vehicle and colour variant, so if you see dark segments, update.Lights also need the engine running, a working battery fitted, and headlight bulbs in the two headlight slots — so if the engine won’t start (see above), the lights won’t either.
This was addressed across the Handling Resimulation & All-Wheel Drive update and finished in The Planted Update (v2.7) — the whole fleet moved to all-wheel drive, every car’s weight balance was re-checked and corrected, over-stiff springs were softened, and first-gear power was matched to the grip the tyres actually have. Wheelspin, rear-end sliding and loose launches are gone on the current version.Update to the latest version of the pack/tier or single-vehicle mod (see the Vehicles Changelog). It’s a drop-in PBO update — no types.xml or server-config changes needed.
v2.9 or later. v2.9 is built for DayZ 1.30 and will not load on 1.29; v2.8 was the last version for 1.29. Every pack, tier and single-vehicle mod moved to v2.9 together, and the free GT-R 2015 and Golf MK4 moved to v1.9. Update the server and every client together.
Update to v2.9 or later. v2.9 calmed the suspension on 80 vehicles so parked cars sit still, and added real ruined tyres: a destroyed wheel bursts and swaps to a flat, torn tyre until you fit a good one. If ruined wheels pile up on the ground, merge the _Ruined entries from the ready-made types.xml so they get cleaned up.
No. The vehicle mods don’t depend on Community Framework. You can remove @CF from your load order unless another mod on your server still requires it. Removing CF will not affect the vehicles.
A spawn problem is a loot/economy or load-order issue, not whitelisting (whitelisting only affects the engine, not spawning):
  • Make sure the vehicle’s classnames (and its wheels/doors) are in your types.xml or placed via your trader/events.
  • Make sure the mod pack is loaded on both client and server, and the PBOs are signed with a key present in the server Keys\ folder.
No — a pack/tier and a standalone mod of the same vehicle both define that vehicle, so loading both at once will conflict. Run either the pack or the standalone for a given vehicle, not both.
The vehicles use standard DayZ car parts. Every vehicle needs its wheels, a battery and headlight bulbs; most also need a spark plug and a radiator. A few do not use a spark plug or radiator at all — the Black Mamba, Bugatti Chiron, Rayfield Caliburn, McLaren 600LT and the three HEMTT bodies — and the HEMTT runs on a truck battery rather than a car battery. There are no custom part items to add to your economy: only the vehicle’s own classnames, wheels and doors are ours.
