Service Action 53: Retrofit Of The Engine Coolant Temperature Sensor (M17 05 12)

SERVICE ACTION 53: RETROFIT OF THE ENGINE COOLANT TEMPERATURE SENSOR

TECHNICAL SERVICE BULLETIN

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 

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.

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).

PARTS INFORMATION

Part Number	Description	Quantity

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:

1. Emboss your MINI dealer warranty number in the middle of the label (1);
2. Punch out code number 53  (2), printed on the label; and
3. 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.

WARRANTY INFORMATION

The repair described in this bulletin is covered under warranty regardless of time or mileage.
