Service

Please read the entire work procedure before starting the actual work so the scope and number of the
repair options are understood completely.
If the event memory entries listed in the workshop findings are found in the diagnostic log, perform the
following:
1. Follow Guided Fault Finding for the DTC and if the result of the test plan states to replace the Parking
Lock Solenoid N486 then proceed with this repair.
If Guided Fault Finding prompts “Is a TPI available for this error?” the response “No” must be
selected otherwise the analysis process will not continue.
If Guided Fault Finding recommends a different repair this TSB does not apply.
2. If the result of the Guided Fault Finding test plan was to replace Parking Lock Solenoid N486 the next
step is to remove the Mechatronics unit per the Elsa Repair Manual.
3. After removing the Mechatronics unit remove the intake filter (Figure 2, positions 8 and 9) to access
one of the filter bolts and perform a visual inspection of the installation of the bolts for pressure filter 2
(Figure 2, position 10 and 11). This is the smaller of the 2 canister filters installed to the mechatronics
unit with 3 bolts attaching the filter to the unit (Figure 3).

Technical Service Bulletin
Option 1
One or more bolts are loose (Figure 4).
You may also see the securing ring is not
flush to the valve body which would mean
the bolts are loose.
If the bolts are loose, replace the cover (with
seal) along with the bolts as described in
ETKA and the Workshop Manual. Claim
Option 1 in the Warranty Table below.

Technical Service Bulletin
Option 2:
One or more bolt heads are broken off or
missing (Figure 5).
Remove the cover for the high-pressure
filter. Attempt to remove the remaining
pieces of the bolts by hand (without tools). If
possible, then install a new cover (with seal)
and the three securing bolts as specified in
ETKA and the workshop manager. Claim
option 1 in the warranty table below.
Only if any of the bolts cannot be removed
by hand, replace the Valve Body per ETKA
and the Elsa Repair Manual. Claim Option 2
in the Warranty Table below.
Figure 5. The bolt head is missing.
Option 3:
All 3 bolts are tight. Replace the Parking
Lock Solenoid N486 and the Pressure
pipe for the N486 (Figure 4) per the Elsa
Repair Manual. Claim Option 3 in the
Warranty Table below.

PHEV Models require transmission
removal which requires the HV system
to be deactivated. Read and follow all
of the Elsa Repair Manual steps and
safety precautions.
