Technical Service

PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL
AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY
ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
SUBJECT

Service Action: Retrofit of the Engine Coolant Temperature Sensor
MODEL

R60 with manual transmission (N16 or N18 engine)
SITUATION

Internal corrosion could form in the engine coolant temperature sensor. This corrosion leads to internal
bridging of the contacts, which can cause an inaccurate engine temperature reading. This false reading
could lead to difficulty in the engine starting and/or a “Service Engine Soon” lamp being illuminated.
AFFECTED VEHICLES

This Service Action involves R60 MINI Cooper/Cooper S vehicles with either N16 or N18 engines
which were produced from 8/2010 to 3/2012.
In order to determine whether a specific vehicle has had this Service Action completed or is affected by
this Service Action, first check the B-pillar label for code 53. If code number 53 has been punched out,
the campaign has already been performed. If code number 53 has not been punched out, it will be
necessary to utilize the "Service Menu" of DCSnet (Dealer Communication System) or the Key Reader.
Based on the response of the system, either proceed with the corrective action or take no further action.
PROCEDURE

This procedure requires the replacement of the upper coolant hose with a modified hose that houses a
new engine temperature sensor. An adapter harness needs to be fitted to the car to utilize this new
sensor.
Remove the fresh air intake tube and the intake tube from the air box to the turbo to gain access to the
coolant hose.

Remove the coolant hose (1). This hose
will not be reused.

female connector (2) of the adapter
harness into the engine thermostat.
Plug the 2-pin female connector (3)
from the adapter harness into the
engine temperature sensor of hose P/N
17 12 9 811 352.

Secure the connector (1) with a cable
tie to the engine wiring harness.

Reinstall the intake components and vent/refill the cooling system (Repair Instruction 17 00 039).
