Mercedes diagnostics with XENTRY & DAS
When a Mercedes control unit sends an error message, the right software is needed. Friedrich AMS works with XENTRY and DAS, the official Mercedes-Benz professional diagnostic software used in every authorized car repair. No generic OBD2 device, no guesswork, precise error reading at dealer level, and direct discussion of the findings with the owner.
XENTRY: complete fault code reading of all control units (engine, transmission, ESP, ABS, airbag, comfort, driver assistance and more)
DAS (Diagnosis Assistance System): guided fault finding according to Mercedes diagnostic logic
ECU coding, calibrations and software updates
Consultation on the findings directly with the technician – easy to understand, without technical jargon.
ECU coding & calibration
After replacing parts, undertaking modifications, or installing driver assistance systems, coding the control unit is critical. Friedrich AMS performs Mercedes coding and calibration using XENTRY – correctly, completely, and with full documentation. This is especially important for cameras, radar sensors, steering angle sensors, and after replacing control units.
Mercedes transmission service: 7G Tronic and 9G Tronic
The 7G Tronic and 9G Tronic automatic transmissions from Mercedes-Benz are among the most powerful and sophisticated units on the market. Friedrich AMS performs transmission service and flushing for 7G Tronic and 9G Tronic transmissions, including XENTRY diagnostics before the flush, ATF oil according to Mercedes specifications, transmission oil filter replacement, and a mandatory control unit reset.

Mercedes Classics & Collector Cars – W124, SL & more
Friedrich AMS has many years of experience with classic Mercedes models and understands the specific characteristics of older vehicles: different generations of control units, older automatic transmissions, rubber parts that age, and wiring harnesses that require maintenance. From the W124 to the current W213, Friedrich AMS services every generation.
What we do for your classic car
Mercedes W124, W210 & W211
The W124 is considered one of the most reliable Mercedes-Benz models of all time. The W210 marked the transition to the modern electronics era. Friedrich AMS is familiar with both generations: injection systems, older automatic transmissions, suspension problems, and typical weak points. We offer specialized service for enthusiasts, engine inspections, and preventative parts replacement upon request.
Mercedes W211 & W213: current E-Class generations
Friedrich AMS offers comprehensive service for the W212 and W213 models: XENTRY diagnostics, manufacturer-specified inspections, 7G Tronic/9G Tronic transmission service, coding and software updates. This includes driver assistance system calibrations according to ADAS standards.
Mercedes SL & Collector's Vehicles
The SL is the most emotionally resonant vehicle in the Mercedes portfolio. Friedrich AMS services SL models of all generations – Pagoda, R107, R129, R230, R231 – with the meticulous care a collector's car deserves. Collector service, seasonal checks, storage, and preventative maintenance are available upon request.
AMG & High-Performance Vehicles
AMG vehicles place special demands on workshops and technology. Friedrich AMS services AMG models with XENTRY diagnostics, AMG SPEEDSHIFT MCT and DCT transmission service, suspension adjustments, and track day preparation. Experience with performance-optimized vehicles and knowledge of AMG-specific electronics form the basis for expert work, without the AMG dealer markup.
