Mercedes Benz diagnostic test in Los Angeles

Mercedes-Benz service engine light

We recommend a Mercedes Benz diagnostic test when your service engine warning light goes on.

The same holds true if you are encountering strange driveability issues, like a rough idle or difficulty starting and running.

A Mercedes Benz diagnostic test will quickly identify the cause of the problem by providing a diagnostic trouble code (DTC) for us to investigate further.

At Jack’s Tri-Star Motors we offer a basic Mercedes Benz diagnostic test for free.

However, if more in-depth analysis is required, for an extra fee we will hook up your car to the same diagnostic testing software/hardware used at local Mercedes dealerships.

FREE Mercedes Fault Code Diagnosis

Mercedes Benz diagnostic test

Our FREE Mercedes fault code diagnosis can be usually be completed in 10 to 15 minutes. We use a hand-held diagnostic tool that identifies the DTC.

For many customers this information is sufficient. However, this tool is not as accurate or provides as many functions as our more advanced diagnostic service.

Advanced Mercedes Benz diagnostic service

Xentry Mercedes diagnostic test

When a more advanced Mercedes Benz diagnostic service is necessary, we use Xentry DAS. It is a full diagnostic assistance system for all Mercedes Benz model series.

This DAS has all the functions we need to diagnosis your Mercedes: reprogramming, configuration, initialization, fault diagnosis and guided diagnostic tests.

When we hook up its developer extension, we are allowed more in-depth manipulation of the configuration, data and programs stored inside your Mercedes electronic control units.

We do not offer this more advanced Mercedes Benz diagnostic service for free because it requires our mechanics to spend between 1 to 1.5 hours of their time troubleshooting.
