VIN Decoder Fail

[masster]

Here is a typical Vehicle Identification Number (VIN) for Skoda Felicia: TMBEEA613V0419133. It is taken from the registration certificate and from the metallic tag located near the lock of the bonnet. We all know that we are asked for it each time we order parts. And each time we get the same answer: Invalid VIN: Failed Checksum. That is because the 9th digit of VIN is a checksum that doesn't match the result of the algorithm.

There are many VIN Decoders online that issue the same error. So my question is: does anyone know why Skoda Felicia VIN numbers are not valid?
