The prerequisites to be observed when checking and
adjusting CRI Piezo can be found in the test instruc-
tions for CRI Piezo in ESI[tronic] 2.0. These test in-
structions do not form part of the scope of delivery.
ESI[tronic] 2.0 can not be installed on the EPS 200.
Procedure:
1. Clean the CRI Piezo (see Sec. 4.3).
i
Perform the "leak test" before fitting the injection
chamber (fig. 21, item 6) on the component.
2. Attach the CRI Piezo (fig. 21 item 7) to the clamp .
!
To avoid twisting and premature wear, do not
connect the high-pressure hose directly to the
CRI Piezo.
3. Connect the high-pressure hose with the connection
adapter (fig. 21, item 8, 9) to the CRI Piezo.
!
The connection adapter must be tightened to a
torque of between 25 Nm and 30 Nm. If the connec-
tion between the connection adapter and the CRI
Piezo is leaking, the screw connection is not to be
re-tightened. In the event of a leak, unfasten the con-
nection again, clean the sealing surface and re-con-
nect the connection adapter applying the correct
tightening torque.
4. Connect the hose 1 680 703 078 to the return of the
CRI Piezo and to the "CRI Piezo return inlet" (fig. 21,
item 1).
5. With a Bosch piezo CRI, plug the adapter with check
valve into the "test connection for return quantity"
(fig. 21, item 3).
!
Do not use the adapter with check valve with
third-party piezo CRIs.
6. Connect the hose assembly 1 680 703 079 to the
"piezo CRI return outlet" (fig. 21, item 2) and the
adapter with check valve or, with a third-party piezo
CRI, to the "test connection for return quantity"
(fig. 21, item 3) of the .
7. Connect the injector-specific adapter cable
(1 684 465 669, 1 684 465 671) to the CRI Piezo
and to the "Socket" (fig. 21, item 5).
!
Route the injector-specific adapter cable such that it
does not come into contact with the hot hoses.
8. Insert the inlet filter in the "Test connection for
injected fuel quantity" (fig. 21, item 4).
9. Close the guard.
10. Perform the test.

i
After the "leak test", fit the injection chamber on the
component and connect the hose 1 680 712 362
to the quick-release coupling of the injection cham-
ber (fig. 21, item 6) and via the inlet filter to the
"Test connection for injected fuel quantity" (fig. 21,
item 4).
