Renewing seals on injectors
Note
♦ Injectors from different manufacturers are used. For alloca‐
tion to the engine, refer to ⇒ ETKA (Electronic parts cata‐
logue).
♦ In the case of version -B- injectors (with bead -arrow-), an
M8 washer must be fitted onto the injector before installing
the seal. This prevents the calibration sleeve from being
pushed up behind the seal.
Special tools and workshop equipment required
♦ Tool set for FSI engines -T10133C-
♦ M8 washer, only for version -B- injectors
Note
♦ In this section, the work procedure for the combustion cham‐
ber seals (Teflon ring seal) is described.
♦ The combustion chamber ring seal must always be renewed
prior to reinstalling the injector.
– Clean injector carefully.

Cleaning injectors
Note
In this section, the work procedure for injectors (combustion
chamber) is described.
Special tools and workshop equipment required
♦ Ultrasonic cleaning unit -VAS 6418-
♦ Mounting plate for injection modules -VAS 6418/1-
♦ Cleaning fluid -VAS 6418/2-
Cleaning
– Close drain tap -arrow- of ultrasonic cleaning unit -VAS
6418- at right-hand side of housing.

– Fill ultrasonic cleaning unit with 2120 ml of water which was
allowed to stand for a while and with cleaning fluid -VAS
6418/2-.
Mixing ratio for cleaning fluid
•
2100 ml of water which was allowed to stand for a while and
20 ml of cleaning fluid -VAS 6418/2-.
– Remove injectors ⇒ page 427 .
– Fit mounting plate for injection modules -VAS 6418/1- onto
cleaning unit.
Note
♦ Before starting ultrasonic cleaning unit -VAS 6418-, it is es‐
sential that the safety information described in the operating
manual is observed.
♦ The ideal fluid level is reached when the cleaning agent is
approx. 1 to 4 mm above the base of the mounting plate.
The ultrasonic cleaner -VAS 6418- could become damaged
if the fluid level is too low.
– Insert injectors into guides of mounting plate for injection
modules -VAS 6418/1- as far as stop.
– Switch on cleaning unit by pressing on/off button -C-.

– Set rotary knob -B- to a temperature of 50°C.
– Press button ► -D- to start the cleaning process.
Note
♦ Temperature-controlled cleaning is now activated. During
the warm-up period, ultrasonic waves are activated to mix
the cleaning fluid. Once the preselected temperature is
reached, the ultrasonic waves are switched to continuous
operation.
♦ The cleaning time must be at least 30 minutes and cleaning
only starts at a temperature of at least 50°C.
– Each time after cleaning injectors (combustion chamber),
renew combustion chamber seal (Teflon ring seal) ⇒ page
435 .
– Install injectors (combustion chamber) ⇒ page 427 .
