Introduction to the new
Maserati GranTurismo

DATE: APRIL 26 2023
The new Parts & Service mission aims to ensure a unique customer experience. A few important guidelines
for the technical management of the New Maserati GranTurismo are set out in this bulletin. The GranTurismo
coupé combines high performance, typical of a sports car, with comfort suitable for long journeys, setting
the benchmark and fully embodying “The Other Just Travel” concept.
Developed at the Maserati Innovation Lab and made at the Mirafiori Plant in Turin, the GranTurismo is 100%
entirely made in Italy and an expression of the trademark Maserati "Italian luxury performance” concept.
The new coupé is equipped with a revolutionary Neptune V6 engine that comes in two versions, namely the
Modena version equipped with the 3.0-liter V6 Neptune Twin Turbo delivering 490 hp, and the highperformance Trofeo version based on the same engine, which reaches a peak output of 550 hp.

1 Vehicle maintenance and periodic battery checks
The specifics on the maintenance of the vehicles in stock are reported as usual in the dedicated circular
letter which undergoes periodic updates (MAS003441 and its subsequent revisions). In particular, the
new Maserati GranTurismo features require more restrictive 12V battery charge status control logistics
than other models in the Maserati family. The checks involve:
-

Performing a Battery test using the E-XTEQ MAXIMUS at PDI.
Performing a Battery test using the E-XTEQ MAXIMUS during the entire storage period.

1.1

12V Battery Inspection at PDI

Performing a Battery test using the E-XTEQ MAXIMUS at PDI.
Result = Battery is Good:
• Voltage 12.6V or above = PROCEED WITH LOGISTICS MODE REMOVAL
• Voltage 12.5V or below = RECHARGE THE BATTERY
Result = Battery is Bad:
•

1.2

REPLACE BATTERY

Check/ restore 12V battery State Of Charge (SOC)

Performing a Battery test using the E-XTEQ MAXIMUS during the entire storage period at Intervals
outlined in “MAS003441 - Management of Maintenance of vehicle in stock”. (To be released soon)

TECHNICAL SERVICE OPERATIONS

2 Best practices in the workshop for GT service
The following chapter includes a list of best practices and technical notes for Maserati GranTurismo
Service; this vehicle’s features require precautions that may otherwise not be noticed or highlighted
while the car is undergoing normal operations in the workshop.

2.1 Lifting the vehicle.
The position of the lifting points is indicated by an inverted triangle stamped on the edge of the body;
there are also vehicle side pads for interfacing the axle positioning.

Front pad

Rear pad

Be careful about the axle geometry to prevent damaging the vehicle during the lifting operation. We
recommend removing all possible loads from the vehicle (passengers, luggage, spare tire, etc.) to
increase the distance from the ground (in case there are no air springs).

We recommend using plates with a diameter no greater than 125mm for the front axle and centering
the plate on the lifting dowel as well as possible to prevent contact with the car’s floor trim.

Transmission Park Release

TECHNICAL SERVICE OPERATIONS

2.6

If you need to move the car with the engine off, the “Car Wash” mode can be activated
as shown below:
-

The car must be on a level surface, not moving.
Put the transmission in N (Neutral) by using the control on the dashboard.

-

Turn the engine off by pressing the START/STOP button

The driver’s door must be shut during these steps. This condition must be maintained for about 15
minutes, after which the transmission moves to P (Park).
If this solution is not possible or if there are other transmission problems, the transmission can be
released manually as follows:
-

Lift the car just enough to be able to reach the inside central area
Identify the automatic transmission and the release actuator lever

Warning: the transmission park release lever actuator is not in the car: you need to use an
M6 screw at least 32.4 mm long.

3 Pre-Delivery inspection checklist
On the launch of the new GranTurismo, the inter-functional Technical Team consists of personnel
belonging to the Product Support, Engineering, Quality, Spare Parts, Customer Care, and RAM
departments. In addition to introducing various innovative technical contents, GranTurismo represents
the model we expect to generate an important increase in sales volumes and an important challenge

and effective investigation of all reported anomalies.

On the launch of the new GranTurismo, the inter-functional Technical Team consists of personnel
belonging to the Product Support, Engineering, Quality, Spare Parts, Customer Care, and RAM
departments. In addition to introducing various innovative technical contents, GranTurismo represents
the model we expect to generate an important increase in sales volumes and an important challenge
to guarantee maximum satisfaction to our customers. The Technical Team aims to provide maximum
support for correct diagnosis and resolution at the first intervention of cases in the network and a rapid
and effective investigation of all reported anomalies.
Within the first 6 months after the start of the sale, a BOL must be submitted before any work is performed
even if a solution is available. Please review bulletin MAS003088 “New Blue On Line Policy Update” (and
or its subsequent revisions). For further details.
During this period, and before carrying out any service intervention related to an alleged product
quality problem, any anomaly must be reported to the Technical Support team by opening a Blue On
Line report as "Information to the Factory".
If a BOL was opened as "Support Request" or " Request of authorisation to claim” by mistake. Then, a
refund may be requested equal to 0.2 hours of labor when entering the report as "Information to the
factory" by entering the warranty claim of the operation code 0.20.001.A - Information to the Factory 0-3
MIS (0.2 h).
ALL Blue On Line reports must be detailed, complete, and include; Parameters, DTCs, Videos, Images,
etc., and must document the complaint/fault(s) so that Technical Support can assist effectively and
promptly. For hard-to-diagnose concerns, Product Support may coordinate with the technical Support
Team to arrange on-site diagnosis by sending a TA to the site as a last resort.
To monitor the correct progress of the vehicle repair, maximum care is required in manually setting the
Service Entry status. Please also remember that the Service Entry status is automatically set up in
"Awaiting Spare Parts" when the parts to be replaced are related to interventions covered by the
contractual warranty and ordered in VOR mode. With a view to product improvement, and to allow
Maserati to improve the diagnostic effectiveness, you will also need to analyze promptly the defective
components replaced. For this purpose, applying the following indications for the entire duration of the
Technical Team is required:
1. The warranty claim must be entered within two working days of closing the Service Entry
2. The components replaced and requested for urgent return must be sent within two working days
of receiving the request and by the operating procedure indicated in Warranty Bulletin
MAS001556.
