SUBJECT

Service Action: N14 Engine Check Timing Chain Tensioner and Timing Chain
MODEL

R55
R56
R57
With the N14 engine
SITUATION

The timing chain tensioner applies pre-tension to the timing chain guide rail mechanism. In some
cases, the tensioner spring force may be too low. Depending on the severity of the wear, it may lead
to a rattling noise when starting the engine cold or when the engine is idling.
CAUSE

The timing chain tensioner internal tolerances are not consistent.
AFFECTED VEHICLES

This Service Action affects certain MINI models equipped with the N14 engine, produced from
11/2006 to 5/2009.
First check the B-pillar Service Action label for code number 61.
If code number 61 has been punched out, the campaign has already been performed and no
further action is necessary.
Vehicles which require this Service Action to be completed will show it as “Open” when
checked either in the "Service Menu" of DCSnet (Dealer Communication System) or with the Key
Reader.
PROCEDURE

Inspecting the Chain Tensioner:
1. The timing chain tensioner will need to be inspected before removal. The timing chain
tensioner is visible from above, inside the engine compartment, between the intake tube and

air filter housing. One of the following timing chain tensioners may be installed. Do not
remove the timing chain tensioner for the inspection.

Item 1: Protruding boss – Not OK

Item 3: Drilled head – OK

Item 2: Flat head, no markings, no holes, no machined
edge – Not OK

Item 4: Machined edge in
head – OK

2.

If the engine is fitted with a timing chain tensioner that has a drilled head (item 3) or has
a machined head (item 4), do not replace the timing chain tensioner. No further repairs are
needed. If the chain tensioner has a protruding boss (item 1) or a flat head (item 2), proceed
to step 3.

3. Remove the right-hand wheel arch trim to access the crankshaft central bolt.
4. Disconnect the battery and remove the ignition coils and spark plugs. Turn the engine in
clockwise direction by hand to move the flywheel approximately 90° before TDC. Rotating
the engine counterclockwise may cause an incorrect measurement.

5. Install the locating pin (Special

Tool 11 9 590) to lock the
position of the engine.
Note:
Do not remove the cylinder
head cover! Do not install the
camshaft locking tool during
this procedure. To achieve an
accurate measurement, the
camshafts need to rotate.

Remove the chain tensioner and collect the residual
oil with a shop towel.
6. Fit the chain tensioner (Special
Tool 11 9 340) without the
seal ring and with the lock nut
loose. Pretension the chain
tensioner with Special Tool 00
9 250 to 0.6 Nm. Fingertighten the M10 lock nut on
Special Tool 11 9 340.
Note:
Gently turn Special Tool 00 9 250
while applying the torque. Quickly
rotating the tool will provide an
inaccurate measurement result.

7. Remove chain tensioner
Special Tool 11 9 340 from the
engine, with the lock nut still
tight. Measure the distance
(A), as described in the
illustration.

8. If distance A is less than 68 mm, replace the chain tensioner with sealing ring P/N 11 31 4
609 482 (refer to parts list A).
9. If distance A is 68 mm or greater, replace the components below, found in the Timing Chain
Repair Kit P/N 11 31 8 623 601 (refer to parts list B):


Timing chain tensioner



Sealing ring



Timing chain



Guide rail



Tensioner rail



Sliding rail



Sprocket on the crankshaft



Bearing bolts for the tensioner and guide rails

Refer to Repair Instruction 11 31 051, “Replacing timing chain N14.”
During the replacement of the timing chain module (guide rails), inspect for missing or broken
parts. If portions of or the entire guide rail(s) are missing, it is very likely these component
fragments have migrated into the engine oil pan.
In this case, remove the engine oil pan to retrieve the component fragments and replace the engine
oil and filter.
Note: If the engine oil service is showing “Recommended” or “Due,” reset the CBS data.
Refer to Repair Instruction 11 13 000, “Removing and installing, sealing or replacing oil pan
(N14).” (Refer to parts list B and C.)
Do not replace the front crankshaft hub seal unless it is found to be leaking or damaged.
Refer to the EPC for additional onetime-use parts as required, e.g., gaskets, seals, bolts, etc.
Do not replace the hydraulic valve lifters (HVA), intake camshaft VANOS adjustment unit,
or the exhaust camshaft sprocket for this repair. Refer to the Warranty section of this
bulletin for more details.

LABEL INSTRUCTIONS

This Service Action has been assigned code number
61. After the vehicle has been checked and/or
corrected, obtain a label (MD20–064) and:
A. Emboss your MINI dealer warranty number in
the middle of the label (1);
B. Punch out code number 61 (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 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.
