Read the reviews after purchase
Read the reviews after my purchase and I’m so confused by the bad reviews. Seems some customers are getting companies names mixed up as my experience was great. A shame that false reviews seem to be posted.

What Are Mercedes Mileage Blockers?

A Mercedes mileage blocker is a vehicle-specific electronic module designed to control mileage recording while the device is active during controlled testing applications. Mercedes vehicles use different chassis codes, generations, and electronic configurations, so the correct module depends on the exact vehicle application.

Smelecom supplies Mercedes mileage blockers for supported models including C-Class, E-Class, A-Class, GLC, GLA and GLE. Before selecting a module, confirm your chassis code, production year and dashboard configuration to identify the correct fitment.

Mercedes Mileage Blockers Start With Your Chassis Code

Mercedes model names alone do not always confirm compatibility. The same model badge can cover different generations, body styles and electronic systems, which is why Mercedes chassis codes are an important part of choosing the correct mileage blocker.

For example, a C-Class W205 and another C-Class generation are different applications, while an E-Class W212 cannot be treated as the same vehicle as an E-Class W213. The chassis code helps identify the correct module before considering other details such as dashboard configuration and production year.

Smelecom provides vehicle-specific Mercedes mileage blockers for supported chassis applications, including:

  • C-Class W205/V205/S205/C205/A205
  • A-Class W177 and W176
  • GLC W253/C253
  • GLA X156
  • GLE C292
  • E-Class W212/W207 and W213/A238

To know which chassis code applies to your Mercedes, check your vehicle information or contact Smelecom with your model, year, and dashboard details before ordering.

Choosing the Correct Mercedes Mileage Blocker

Selecting the correct Mercedes mileage blocker requires more than choosing the model name.

Before ordering, confirm:

  • Mercedes chassis code
  • Production year
  • Body style
  • Instrument cluster/dashboard configuration
  • Product compatibility information

Mercedes vehicles can receive updates during their production cycle, meaning two vehicles with the same model badge may require different applications.

For example:

  • A C-Class W205 module is designed for supported W205-family applications and should not be treated as suitable for every C-Class generation.
  • An E-Class W212/W207 module is separate from the later W213/A238 application.
  • A GLA X156 and GLC W253/C253 require different modules despite both belonging to the Mercedes SUV range.

Choosing by chassis code first helps avoid selecting a module designed for another Mercedes configuration.

Mercedes Models Covered by Smelecom

Smelecom provides dedicated Mercedes mileage blocker applications for selected models and chassis configurations.

Mercedes C-Class

The Mercedes C-Class W205 mileage blocker covers supported W205, V205, S205, C205 and A205 applications from 2014 to 2021. Because Mercedes C-Class vehicles are available in different body styles and generations, confirm your chassis and dashboard configuration before ordering.

Mercedes E-Class

The Mercedes C-Class W205 mileage blocker covers supported W205, V205, S205, C205 and A205 applications from 2014 to 2021. Because Mercedes C-Class vehicles are available in different body styles and generations, confirm your chassis and dashboard configuration before ordering.

Mercedes A-Class

Mercedes A-Class vehicles are available across different generations, including W176 and W177 applications. The chassis code and production year should be confirmed before ordering, as newer and older A-Class models use different vehicle systems.

Mercedes GLC

The Mercedes GLC W253/C253 mileage blocker is listed for supported 2015–2022 applications. Check your vehicle dashboard and product details before ordering to confirm compatibility.

Mercedes GLA

The Mercedes GLA X156 mileage blocker is designed for supported 2013–2019 applications. The GLA uses a different platform from other Mercedes SUV models, so a similar-looking vehicle does not necessarily use the same module.

Mercedes GLE

The Mercedes GLE C292 mileage blocker covers supported 2015–2019 applications. Confirm your GLE generation before selecting a product.

If your Mercedes model is not listed, do not choose a similar-looking module. Contact us with your chassis code, model year, and dashboard details so compatibility can be checked.

Plug-In Mercedes Applications

Smelecom Mercedes mileage blockers are developed for specific vehicle applications, with each module matched to the supported chassis and electronic configuration. This means the fitting process can differ between Mercedes models, even when vehicles belong to the same model family.

Always use the installation instructions supplied with your exact product to ensure the correct fitting method is followed for your Mercedes.

Still finding out which module matches your Mercedes? Provide Smelecom with your model, chassis code, production year and dashboard details before ordering.
