SUBJECT

Service Action: Retrofit of the Engine Coolant Temperature Sensor
MODEL

R60 with automatic 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

The existing engine temperature sensor will be bypassed electrically, and a new engine temperature sensor will be
installed remotely and wired into the vehicle’s engine harness. The new engine temperature sensor, with integrated
wire harness, will be installed in place of the thermostat bleeder screw.
Note: This Service Action does not apply to any N16 engine that had a thermostat replaced with P/N 11 53 7
534 521. Vehicles equipped with the N16 engine may have had repairs performed prior to this Service Action, so
installing this remote sensor and hose or the sensor in place of the bleeder screw is no longer required.
The 11 53 7 534 521 thermostat would need to be installed in conjunction with an engine electrical wiring harness
replacement. This thermostat already has an updated, replaceable engine coolant temperature sensor.
If the vehicle is in the workshop for this Service Action and also requires an engine wiring harness replacement:


Replace the engine wiring harness with the 11 53 7 534 521 thermostat.



Do not install the remote engine temperature sensor. Claim the labor operation “Check for 11 53 7 534 521
thermostat installation” in the Warranty Information section of this bulletin.



Affix the Service Action label to the B-pillar.

Checking for the updated thermostat:
The 11 53 7 534 521 thermostat has a
replaceable engine temperature sensor
(1).

Remove the fresh air intake tube and the intake tube from the air box to the turbo to gain access to the coolant
hose.

The improved sensor (P/N 13 62 8 603
908) includes the temperature probe
(1) and insulating sleeve (2), a two-pin
female connector (3) for the map
thermostat, and a four-pin connector
(4) for the engine harness.

Relieve the coolant pressure by
removing the reservoir cap, and then
re-tighten.

Remove the bleeder screw (1) from the
thermostat. This screw will not be
reused.

The back of the temperature sensor is
slotted to accept a bladed screwdriver
(1). Install the sensor into the bleeder
screw hole, and torque to 2Nm.

Slide insulating sleeve (1) onto the
temperature sensor. The sleeve must
completely cover the sensor.

Install the two-pin female connector
(1) into the thermostat and the four-pin
male connector (2) into the engine
wiring harness.

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

Secure the wiring from the temperature
sensor (1) with a cable tie.

Reinstall the intake components and vent/refill the cooling system (Repair Instruction 17 00 039).
Note: This repair procedure involves draining a small quantity of coolant; refill the drained quantity with new
MINI Long-term Antifreeze/Coolant (50/50 mixture). Do not reuse the drained coolant.

LABEL INSTRUCTIONS

This Service Action has been assigned code number
53. After the vehicle has been checked and/or
corrected, obtain a label (MD20–040) and:
A. Emboss your MINI dealerr warranty number in
the middle of the label (1);
B. Punch out code number 53 (2), printed on the
label; and
C. Affix the label to the B-pillar as shown.
If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the
old one. Do not affix one label on top of another one because a number from an underlying label could appear in
the punched-out hole of the new label.
