The complexity of starter removal depends on model (see below for more details):
* In case of [[4Matic]] complete exhaust system has to be removed.
* In case of S400 CDI/S600/S65L AMG right catalytic converter has to be removed.
* In case of S600/S600 PULLMAN front right exhaust system has to be removed.
* In case of S280/S320/S320 CDI/S350/S430/S500 starter can be removed without major problems.

Removal/installation on S350

Starter is attached to transmission and crankcase with two E14 torx bolts. Starter can be removed from underneath the vehicle - only plastic shields have to be removed. Since there is not much space the process is not very convenient but is possible.
