Mercedes Benz Catalytic Converters

Mercedes Benz Catalytic Converters are classified as foreign catalytic converters and have very distinct numbering for their serial numbers. It is essential to look at and send all the codes on the converter when looking to get a price, as more information from you leads to quicker prices from the team at

While Mercedes Benz’s are expensive- their catalytic converters could be both low and high value. These cars typically have 1-2 catalytic converters, and Mercedes does an excellent job of having serial numbers stamped right on the units.

This allows them to be easily recognized as OEM (what’s that?) units and have multiple serial numbers listed at a time. This part could be confusing, but we always ask for all the numbers listed so our team can locate the correct one quicker and quote it out sooner. Mercedes cats rarely contain O2 sensors and are almost always labeled to make things much more manageable.

What does a Mercedes Benz Catalytic Converter Look Like?

Depending on where they come from, they could have a brighter color and generally always have the Mercedes logo. There are a lot of diesel cars that Mercedes produces, and many times those cars will have 1-2 catalytic converters on them – and those catalytic converters could have mixed values.

Some of the diesel units are called DPFs (Diesel Particulate Filters) and have little to no value other than scrap steel pricing – the team at will be able to tell you which unit you have and will be able to help you identify those DPFs that are very valuable in scrap.

Everyone thinks Mercedes Benz catalytic converters or other European catalytic converters always have a high value. Still, many of these could be foil cats and be less valuable than their ceramic ones. To be sure, send us pictures and the serial numbers of your Mercedes Benz units for an accurate price quote.


Mercedes Benz Catalytic Converter Traits:

Below are some general tips for identifying the Mercedes Benz cats you may have.

  • They have 8 to 11-digit serial numbers.
  • 2-3 sets of numbers/codes will be listed.
    • Example:  KT0121 = different ranges. 
    • Often people send us messages with the letter “O” instead of the number “0” (zero). Not only on Mercedes Benz but all cats, the “0” you see will be zero instead of the letter “O.”
  • Some Mercedes Cats look like catalytic converters but are resonators/mufflers and have a serial # on them that we can run and help you learn.
