Pre-1981 chassis numbers SS Jaguar, Mark IV–IX, XK120–150, C/D-Type, XKSS, MkI/MkII, Mark X, 420G, E-Type Series 1–3, XJ Series 1–2, early XJ-S and the Daimler range are identified from the chassis number, with their own service data and buyer's watch points. Manufacturer bulletins do not exist for these cars — the archives begin in the 1990s — so that section is shown empty rather than filled with someone else's data.
XJ220 281 cars built, and neither JagRepair nor NHTSA holds a single bulletin for them. The decoder says so explicitly instead of leaving the block blank.
How to find and enter your number
- Modern Jaguar (1981–2026) — 17-character VIN starting with SAJ or SAD. Found on the A/B-pillar sticker, visible through the lower-left corner of the windscreen, or stamped in the boot. Enter all 17 characters exactly as shown.

Help us close the last gaps — especially outside North America
The bulletin corpus comes from NHTSA, which by law only covers cars sold in the United States. Every platform now decodes and returns full service data, but a handful of VIN character codes have only ever been seen on US cars — and the equivalents used on UK, European, Japanese and Australian cars are still unconfirmed. If your VIN decodes with a field left blank, or you have factory spec sheets or a market-specific decode table, send it over. Each confirmed code goes straight into the decoder for everyone.

This decoder is actively being developed and improved. While we strive for accuracy using official factory specifications,
some data may be incomplete or contain errors — especially for rare variants, regional markets, and early production vehicles. Always verify critical information with a qualified Jaguar technician before carrying out maintenance or repairs.

Frequently Asked Questions
What does a Jaguar VIN number tell you?
A 17-digit Jaguar VIN encodes the manufacturer (SAJ = Jaguar UK), market and airbag specification, transmission type, body style, engine emission level, model year, assembly plant with engine variant, and a unique serial number. This decoder reveals all fields using official Jaguar factory documentation.
Which Jaguar models does this VIN decoder support?
This decoder supports all Jaguar models built between 1978 and 2015, including the XJ6 Series 3, XJS, XJ40, X300, X308 (XJ8), X100 (XK8/XKR), X150 (XK), S-Type (X200), X-Type (X400), X350 (XJ), X351 (XJ), XF (X250), and F-Type (X152). Both UK-format (SAJJ) and standard SAJ VINs are supported.
How do I identify the engine from a Jaguar VIN?
On modern Jaguar VINs (post-1995), position 11 encodes the assembly plant and engine variant. For example, "N" = Browns Lane AJ27, "5" = Castle Bromwich 4.2L V8, "L" = Castle Bromwich 5.0L V8. On older European VINs, position 8 directly encodes the engine type. This decoder extracts both formats automatically.
Where is the VIN stamped on a Jaguar?
Jaguar VINs are found in three locations: a sticker on the A-pillar or B-pillar (depending on model), a metal stamp in the boot (luggage compartment) or on the front suspension turret, and a quick-reference plate visible through the lower-left corner of the windscreen. Always cross-check all three to verify authenticity.
Does this decoder support the XJ220 or XJR racing cars?
The Jaguar XJ220 (1992–1994, 281 road cars) has a standard VIN beginning SAJJ with serial numbers in the 220xxx range — this decoder fully supports it. The XJR-15 (1990–1992, 53 cars) was built by JaguarSport Ltd with a non-standard SAB VIN prefix and is outside scope. Pure racing XJRs (Group C race cars: XJR-8, XJR-9, XJR-12 etc.) and historic models (C-Type, D-Type, E-Type racer, XJ13) predate the modern VIN standard and use their own chassis numbering.
What do the letters in a Jaguar VIN mean?
SAJ = Jaguar Cars UK (World Manufacturer Identifier). Positions 4–9 are the Vehicle Descriptor Section: market/airbag code, transmission, body style, engine emission standard, and check digit. Positions 10–17 are the Vehicle Identifier Section: model year letter/digit, assembly plant and engine code, and 6-digit serial number.
What transmission fluid does my Jaguar XK8 use?
XK8 (X100, 1997–2002) with AJ26 engine uses Esso LT 71141 in the Mercedes-Benz 722.6 5-speed automatic, capacity 10.0 L. Later AJ27-engined cars (from approximately serial A25000) use Shell M1375.4 in the ZF 6HP26. XKR with supercharged AJ26 uses Shell ATF 3403 M115, 9.5 L. Enter your VIN above to confirm which applies to your specific car.
How much coolant does a Jaguar XKR hold?
Coolant capacity varies by engine. XK X150 with 4.2L or 5.0L naturally aspirated: 9.5 L. XKR 4.2 SC (to VIN B32752): 12.35 L. XKR 5.0 SC (from B32753): 13.8 L. The supercharged variants hold up to 4.3 L more due to the intercooler cooling circuit. Use OAT-type antifreeze and always check your specific VIN above.
What spark plugs does a Jaguar XJ X350 4.2 use?
XJ X350 with 4.2L V8 uses AJ8 4575 iridium plugs with a gap of 0.9–1.0 mm, replacement interval 60,000 km. The 3.0L V6 variant uses XR8 42795 or C2S 46895, gap 1.32–1.42 mm. The 2.7D TDV6 diesel has no spark plugs. Enter your VIN above for the exact specification for your engine.
What is the firing order for a Jaguar V12?
The Jaguar 5.3L and 6.0L V12 (XJ12, XJS, XJ81) firing order is 1A-6B-5A-2B-3A-4B-6A-1B-2A-5B-4A-3B. Bank A (right side) is cylinders 1A–6A, Bank B (left side) is 1B–6B, numbered front to rear. The decoder shows an interactive cylinder diagram for your specific engine when you enter a VIN.
