How do I compare the OE number?

What is an OE number anyway?

The car manufacturers name each part with a distinctive article number, the OE number (Original Spare Parts Number or Original Equipment Number), which is almost always used in the aftermarket as a reference to ensure that it fits the vehicle perfectly.

Where can I find these numbers?

Each original part is provided with the respective OE number. These are usually engraved or printed. Some parts are installed in the vehicle in such a way that the OE number can be read without dismantling, but there are also many parts that are not easily accessible or visible.

Every car manufacturer has its own parts program, which - by stating the chassis number - provides information about the installed parts You can obtain information free of charge from the parts service of your dealer.

Also we, as automotive parts experts, have parts programs to identify almost every original part. You are welcome to contact us! We will of course help you to find the right part.

Note: In order to find the right part quickly, we need 2 details about your vehicle: key number and chassis number.

How are the numbers structured?

Many car manufacturers hide the model name in the article number behind specific parts. For example:
Mercedes-Benz:                A2113200304 fits Mercedes E-Class W211
VW:                                         7L
0616007A fits for VW Touareg (7L)

However, this is only a rough insight into the use of the spare part, no use can be identified with certainty.
Important: The number to be compared must match exactly. A deviation from the last letter, for example, can lead to the part not fitting!

Good to know: Optimization, adaptation or the existence of different variants results in several OU numbers for one and the same part. So do not get confused if there are several reference numbers for one part. It is important that your required OE number is available in the list.
