Complete Service Manual coverage for late
model year Mercedes-Benz vehicles requires
four individual manuals:
Service Manual, Engine
Service Manual, Chassis and Body
Service Manual, Automatic Climate Control
Electrical Troubleshooting Manual
Throughout these manuals, the vehicles are
identified by their chassis and engine numbers.
These numbers are made up of the first six digits
of the respective serial number. For the actual
location of chassis and engine numbers, see
page 00-015/l. In cases where the repair
instructions apply to all versions, only the first
three digits of the respective number are
referenced.
For example, chassis 124 applies to all 124
models. However, chassis 124.128 would apply
only to model 3000 2.5 Turbo.
