The chassis number for these model its composed of an initial fixed letter which is B, followed by a number that can go from 1 to 756 and finally two letters of which the first one determines the series of the model.

Depending on the first letter of the last two letters of your chassis number you can determine what series your car is and look up any modifications done through the range.

(Left hand drive models have an L preceding the last two letters)
