Mercedes-Benz C-Class service history check — official dealer records

C-Class generations and market history

The Mercedes-Benz C-Class has been Mercedes's volume executive offering across multiple generations: W202 (1993-2000), W203 (2000-2007), W204 (2007-2014), W205 (2014-2021), and the current W206 (2021-present, with the C 300 e PHEV and AMG C 43 / C 63 variants). The C-Class is the volume seller for Mercedes-Benz UK alongside the E-Class, with strong company-car uptake. The W206 introduced the EQ Boost mild hybrid as standard and ditched 6-cylinder petrol engines in favour of 4-cylinder turbos with PHEV options.

C-Class-specific service points

Mercedes C-Class records should show alternating Service A and Service B entries via the ASSYST PLUS system. AMG and AMG Line variants follow the same schedule but typically wear consumables (brakes, tyres) faster — verify accordingly. AdBlue service records are relevant on diesel models.

C-Class years with good record coverage

Reliable digital coverage for W204 (2007+), W205 (2014+) and W206 (2021+). W203 records may be partial depending on supplying dealer migration. The C 300 e PHEV records include high-voltage battery health checks; AMG C 43 (mild hybrid) records include EQ Boost system entries.

Year and trim-specific things to check

C 300 e plug-in hybrid (W205 facelift and W206): annual high-voltage battery health check entries are critical. AMG C 43 (W205, W206 with mild hybrid): EQ Boost system entries should appear; oil-service discipline is critical. AMG C 63 S (W205 V8) and new C 63 SE Performance (W206 4-cylinder PHEV): strict oil-service discipline. 9G-Tronic 9-speed auto (W205 from 2015, W206 onwards): oil and filter change every 96,600 km on Mercedes' published schedule is critical. Diesel variants (C 200d / C 220d / C 300d): AdBlue refills and DPF entries should appear regularly.
