Get Maintenance and care -> Engine compartment Guide for Mercedes GLE SUV Fourth Generation (2020-2026)

The vehicle can detect if certain wear parts need

to be replaced or if malfunctions have occurred in

vehicle systems. If the Telediagnostics service is

activated, relevant data is automatically transmit-

ted to the manufacturer. If fault conditions are

detected by the vehicle system self-diagnosis, the

system transmits recommendations for action to

the Mercedes-Benz customer centre depending

on the fault detected. The customer centre trans-

mits the data to the service partner that you have

entered on the Mercedes me website at:

www..

For selected faults, the notication that a mal-

function has been detected may appear in the

multimedia system with a request to contact the

Mercedes-Benz Customer Centre. From this mes-

sage, a call can be made directly to the customer

centre for assistance.

The transmission of a notication to the multi-

media system depends on the country, vehi-

cle model and equipment and requires a fast

data connection, over which the service pro-

vider has no inuence.

Reliable fault detection is subject to technical

limitations. Therefore, only a limited selection

of faults can be detected and recommenda-

tions for action transmitted to the customer

centre and the service partners. Mercedes-

Benz AG is continuously working on the

expansion of this service. The fault detection

depends on the country, vehicle model and

equipment.

Data transferred when using Telediagnostics

When the service is activated, relevant data is

automatically transferred to determine the

required scope of maintenance as well as fault

detection and fault rectication.

Details on data transfer can be found in the data

protection information for the Mercedes me con-

nect services. These can be found at:

www. under "My Mercedes me

account", "Terms of use".

The scope of the transmitted data depends on

the vehicle model and its equipment. For

technical reasons, not all data is available at

all times.
