What The Z's Mean

VINs outside North America, and the VINs found stamped into the rain tray of all Cabriolets, contain four "Z"s. For North American Cabriolets, these are merely filler digits. The rain tray VINs were standard issue as the cars rolled off the initial phase of the assembly line; the only difference between these standard-issue model-year VINs is the sequential production number. Locations outside of the USA & Canada do not require the same VIN information (many locations, including Europe, still require only a 13-digit VIN) and, therefore, use filler digits during stamping to make the initial assembly process easier and faster.

Build Sheets

For example, if 30,000 Cabriolets were built for the 1985 model year, the first Cabriolet built for that year would have WVWZZZ15ZFK000001, while the last 1985 Cabriolet would have a WVWZZZ15ZFK030000 stamped into the rain tray. As the cars went through final assembly, they received their official, individual VINs based on their destination; it was at this time that North American Cabriolets obtained their non-"Z" VINs, while cars destined for sale in Europe received the "Z" VIN on the door plate, the dash plate and on the build sheet. Using the same example, that first 1985 Cabriolet was destined for, let's say, the USA; it's official VIN would be WVWCA0158FK000001 (the internal check code varies and may not actually be an 8). The last Cabriolet for 1985 was destined for, let's say, Italy; it's official VIN would be WVWZZZ15Z030000. Two build sheets are shown here (with the last 4 digits blurred for security reasons), so that you can see the differences between these official VINs.

VIN letter

If you doubt the above information, it was all verified by Volkswagen AG: tap the thumbnail to see the official letter. (Thank you so much to Gail W. for providing this letter and its translation! Gail had an issue in being able to transport her Cabriolet from Germany to the USA because of the VIN "discrepancy". This letter was issued to Gail from Volkswagen AG, providing official verification regarding the "Z" information outlined above.)

Chassis Number

Many times parts are dependent upon your car's chassis number, which is VIN-dependent. Your car's chassis number is the sequential production number for your car's model year. An example of this would be the 1984 mid-year change: If you own a 1984 Rabbit Convertible, you'll need to know the chassis number in order to know if your car uses an in-tank fuel transfer pump. The chassis numbers would be listed as follows:

The "15" is not always used. The "To E-11290" would indicate the part is for all Rabbit Convertibles up to 1984 (E) with VIN sequential production number of 11290.

UK "Regs"

In the Cabriolet's era, UK registration (license/number) plates were issued year identifiers based on when the cars were first registered, which did not always occur when the cars were initially bought. These registration year identifiers are letters. The UK's registration method can create some confusion when it comes to the car's model year. For instance, let's say (for example's sake) that a 1985 White Edition was not bought until September 30, 1985; it was a leftover that is now sitting with new 1986 models at the dealer and offered at a steep discount that couldn't be passed up. The owner registered the car a week later on October 7, 1985. We now have a 1985 model year car that has what is, technically, a 1986 model year registration identifier on it. Thus, saying simply "I have a C-reg Cabriolet" does not quite get the job done. It is far, far better (and more precise) to use the model year (10th digit in the VIN) when discussing the car.

Sequential Production Number

Check Digit USA Canada

Step 1: Assign numerical values to all digits. Numbers 1-10 retain their values. Letters are assigned the following numerical values:

Check number value

Step 2: Assign a weight value to each digit based on its position.

Check weight value

Step 3: Multiply each digit's numerical value by its weight value.

Check weight value

Step 4: Add the results (products) from step 3 and divide by 11. The resulting remainder is the VIN check digit; if the remainder is 10, the check digit becomes an "X" in the VIN.

In the above example, the result is 346 / 11 = 32 with remainder of 5. The 5 is the VIN check digit.
