1.3 Procedure when filling with incorrect
fuel
Caution
Irreversible damage to high-pressure components, espe-
cially the high-pressure pump due to lack of lubrication
though diesel can occur when filling fuel tank with incor-
rect fuel. Damage due to seizure and metal particles can be
expected. These metal particles will probably cause further
damage to pressure regulating valves and injectors.
Note
These instructions are intended to guide you through the indi-
vidual work steps by means of a flowchart, with various situa-
tions being taken into account.

fuel)
– Empty fuel tank as far as possible via fuel filler neck using
fuel extractor -VAS 5190-.
Engine codes CJDA, CJDD
Pull off fuel supply line to high-pressure pump ahead of strainer.
Engine codes CPYA, CPYB, CPYC, CPYD, CPYE
Pull fuel supply line from fuel pump -V393 (Inline EKP)- to fuel
filter off fuel filter.
Continuation for all engine codes
– Put open end of line into a suitable container.
– Perform final control diagnosis, and activate fuel pump,
⇒ Page 89, final control diagnosis.
Note
The fuel pump is now activated.
– Repeat procedure, if necessary, until fuel tank is completely
empty.
– Remove flange cover on fuel tank.
– Check fuel tank for filings according to manufacturer specifi-
cations, and drain any fuel from the fuel tank.
– Perform a visual inspection for foreign bodies and filings in
strainer.
