and silicone sealant

As part of injector manufacturing, tolerance ranges for injection

quantity are determined and specified by a six-digit number

combination. These values are used by the DME to compensate for

variations

the individual injectors.

NOTE-

• When replacing an injector, it is essential to carry out an

injector adjustment using the

BMW

diagnostic scan tool.

Working

the HPI system must only be carried out after the engine

has cooled down. Do not attempt to open any fuel lines or

connections

the HPI injection system until the coolant

temperature

below 40° C (approx. 104°

If the engine

not cool, there

danger of residual fuel pressure

spray

the high-pressure system.

When working

the high-pressure fuel system, take particular care

to ensure conditions of

absolute cleanliness and follow the work

sequences described

the repair instructions. Even the smallest

contaminants and/or damage to the threads on the high-pressure

lines can cause leaks.

When working

the fuel system, it

important to ensure that the

ignition coils are not fouled by fuel or oil (especially critical for N54

engines). The resistance of the silicone material

significantly

reduced by heavy

fuel contact. This can cause spark-over and

misfires at the spark

plug.

•

Before servicing fuel system, remove ignition coils and cover spark

plug holes with a cloth.

• Replace fuel-fouled

ignition coils.

When diagnosing engine noise, do not rule out worn timing chain

components. This

especially applicable to high mileage engines

and engines with extended

oil change intervals.

When replacing cylinder head cover gasket, take extra caution when

tightening fasteners and

sealing at metal joining points. (Example:

front timing cover to cylinder head.) There is a small area where

silicone should be applied to seal where the gasket may not seal.

When working around VANOS units keep area clean and free of

silicone sealant. Even a small amount of silicone introduced into

VANOS actuator or solenoid can cause a fault.

Sticky

VANOS solenoid sets cam

position (CMP) sensor codes

Intermittent lifter noise

(N52 engine)

Notes

A sticky or jammed VANOS solenoid can set a camshaft position

(CMP) sensor

fault (tooth error).

The engine may be difficult to start, run rough and have the

MIL

illuminated

with one or more stored faults:

• Cam sensor, inlet signal - signal invalid for synchronization

• Crankshaft-inlet camshaft, correlation - value outside reference

range

• VANOS intake - stiff, jammed mechanically

• Cam sensor, exhaust signal - signal invalid for synchronization

• Crankshaft - exhaust camshaft, correlation - value outside refer-

ence range

• VANOS exhaust - stiff, jammed mechanically

- N52

only: Remove VANOS solenoid, intake or exhaust, depending

on the

fault codes stored and, using shop

air,

gently blow out any

visible particles and

reinstall. If the fault returns, try swapping the

solenoids between banks to see if the

fault follows the solenoid.

- Replace solenoid if

fault cannot be corrected.

An occasional ticking or rattling noise from the hydraulic

valve

adjusters (HVA) elements may occur during cold engine starts or

frequent short-distance driving. This condition can not cause any

damage to the engine, and

usually remedies itself with a longer

driving distance or operating times at

full operating temperature.

this situation, the lifters can bleed down or have trapped air

causing ticking/rattling noise and may require bleeding, as described

below. The

bleed time may take anywhere from two minutes to a

maximum of

30 minutes.

Procedure preconditions:

• Engine running at operating temperature

• Vehicle stationary on a level surface

a properly ventilated area

• Engine oil level correct - not underfilled or overfilled

Bring engine up to an operating speed (no load) of 2000 - 3000

rpm and maintain this speed for three minutes.

2. Let engine

idle for 15 - 30 seconds. Listen for whether the noise is

still present:

If engine is quiet, procedure is finished.

If engine noise still present, repeat procedure; perform steps 1 and

2 up to a maximum of 5 times.

If the noise remains after performing the bleeding procedure 5 times:

proceed by performing the procedure for a

final time, also at an

engine operating speed of

2000 - 3000 rpm, but for a total time

duration of 15 minutes.

If noise returns after multiple bleedings, the

cylinder head may be faulty and require replacement.

Detonation or knock is

erratic form of combustion that can cause

head gasket failure as

well as other engine damage. Prolonged or

heavy detonation can be very damaging. The hammer-like shock

waves created by detonation subject the head gasket, piston, rings,

spark plug and rod bearings to severe overloading. As a first remedy,

try higher octane high detergent fuel or switch brands.

If the faults

center.

The possible causes are: incorrect adaptation values of the high 160

pressure pump control valve or failure of the high-pressure fuel

pump. Begin by resetting adaptations for engine management.

fault codes return immediately after adaptation, the fuel pump may

be faulty.

Replace the

teflon 0 -ring

(arrow)

when fitting and removing the fuel

injector. This also applies to an injector that has just been fitted and

has to be removed again after

engine start.

A new injector with a new teflon

0-ring

should be fitted as quickly as

possible as the Teflon sealing ring could

swell

Also, be sure that the injector is correctly seated when installing. The

injector hold-down must rest

both injector tabs, otherwise the

necessary force is not applied to injector.

Do not clean the nozzle-needle tip of the piezo-injector.

BMW has determined that certain

2007-201 0 model year vehicles

may experience partial failure of the high pressure fuel pump

(HPFP)

on models with the N54 (turbocharged) engine. BMW's emissions

warranty has therefore been extended to cover the high pressure fuel

pump

(HPFP) or 10 years or 120,000 miles, whichever comes first.

Vehicles with a faulty fuel pump may have an

MIL illuminated with

130

various low fuel pressure-related faults stored

the engine control

160

module (DME). Affected vehicles may experience long cranking

times or reduced engine performance (engine

failsafe mode) when

the

HPFP malfunctions.

If the above symptoms are present, contact an authorized

BMW

center for additional information regarding BMW's extended

emissions warranty coverage on the

HPFP.

Notes

On cars with faulty fuel injectors, various fault codes related to fuel

injectors may be stored

the engine control module (DME) with the

MIL illuminated. The engine may lack power, idle erratically, or have

poor

throttle response.

Related faults codes:

o Injector, cylinder 1-6, short circuit or line break

o DME internal fault

o Injector driver circuit failure bank 1-3; bank 4-6

o Misfire faults (faults indicate banks of 3 faulty injectors).

Consult your authorized BMW center regarding injector replacement as

applies to BMW Service Bulletin SIB 12 02

(dated October 2008}.

diagnosing a faulty engine control module (DME), be sure to check

that the

Valvetronic motor was not the root cause of the damage to
