Air�intake�system
The�air�intake�system�is�in�principle�comparable�with�that�of�the�N63B44O1�engine.�The�most
important�change�to�the�air�intake�system�is�the�adaptation�of�the�intake�manifold�air�duct�with
regard�to�the�installation�space�in�the�F85/F86�(see�Section�3.1.1�Front).
The�S63B44T2�engine�is�fitted�on�each�cylinder�bank�with�a�hot�film�air�mass�meter,�as�has�been�in
use�since�the�N20�engine.�The�air�temperature�and�intake�pipe�pressure�sensors�before�and�after�the
throttle�valve�are�identical�to�those�in�the�N63B44O1�engine.
Intake�silencer
The�housing�of�the�intake�silencer�in�the�F85/F86�corresponds�in�its�geometry�to�that�of�the�F15/F16
with�N63B44O1�engine.�The�only�differences�are�in�the�lettering�due�to�M-specific�markings.
The�air�filter�element�differs�in�the�quality�of�the�filter�mat�from�the�N63B44O1�engine�and�the
S63B44T0�engine.�This�modification�to�the�filter�mat�design�has�resulted�in�a�14 %�lower�loss�of

The�cylinder�head�of�the�S63B44T2�engine�has�been�adopted�entirely�from�the�N63B44O1�engine.
4.1.6.�Exhaust�turbochargers
As�already�featured�in�the�S63B44T0�engine,�two�twin-scroll�technology�exhaust�turbochargers
are�used.
The�exhaust�turbochargers�are�supplied�with�exhaust�gas�as�in�the�S63B44T0�engine�via�two
cross-bank�four-into-two�exhaust�manifolds,�which�is�required�for�the�special�functioning�of�the
twin-scroll�exhaust�turbochargers.
The�wastegate�valves�have�been�modified�when�compared�with�the�twin-scroll�turbocharger�unit�in
the�S63B44T0�engine.�The�wastegate�valves�can�now�be�opened�further�in�terms�of�their�opening
angle.�This�was�necessary�in�order�to�comply�with�the�requirements�of�the�ULEV�II�exhaust�emission
standards.�The�wastegate�valves�are�opened�fully�in�the�warm-up�phase.�In�this�way,�a�large�proportion
of�the�hot�exhaust�gases�is�diverted�past�the�turbocharger�turbines�and�routed�directly�to�the�catalytic
converter.�Thanks�to�this�further�opening�of�the�wastegate�valves,�even�more�hot�exhaust�gas�can�now
be�specifically�diverted�in�the�warm-up�phase�to�the�catalytic�converters.�This�system�reduces�the
necessary�warm-up�phase�of�the�catalytic�converters�and�complies�with�the�even�stricter�emission
requirements.
One-piece�wastegate�valves�are�used,�increasing�robustness.
4.1.7.�Catalytic�converter
The�S63B44T2�engine�has�one�catalytic�converter�per�cylinder�bank,�each�with�two�ceramic
monoliths.�The�design�of�the�catalytic�converters�corresponds�to�those�in�the�N63B44O1�engine.
Oxygen�sensors
The�established�Bosch�oxygen�sensors�are�used:
•
Control�sensor:�LSU�ADV
•
Monitoring�sensor:�LSF�4.2
The�control�sensor�is�located�ahead�of�the�primary�catalytic�converter,�as�close�as�possible�to�the
turbine�outlet.�Its�position�has�been�chosen�so�that�all�the�cylinders�can�be�recorded�separately.

4.1.10.�Fuel�preparation
The�fuel�preparation�components�of�the�S63B44T2�engine�have�been�adopted,�except�for�the
solenoid�valve�injectors,�entirely�from�the�S63B44T0�and�N63B44O1�engines.
A�new�component�is�the�fuel�low-pressure�sensor,�which�measures�and�monitors�the�fuel�pressure�on
the�low-pressure�side.�The�fuel�low-pressure�sensor�is�connected�to�and�monitored�by�the�DME�2.
For�further�information�on�the�fuel�preparation�system�of�the�S63B44T0�engine,�please�refer�to�the
Technical�Training�Manual�“S63�Top�Engine”�and�“N63TU�Engine”.
The�high-pressure�fuel�injection�valves�have�been�adapted�to�the�requirements�of�exhaust�emission
standards.�Solenoid�valve�injectors�that�support�the�software�function�of�so-called�“Controlled�Valve
Operation”�(CVO)�are�used.
For�further�information�on�“Controlled�Valve�Operation”�(CVO),�please�refer�to�the�Technical�Training
Manual�“S55�Engine”.
Work�on�the�fuel�system�is�only�permitted�after�the�engine�has�cooled�down.�The�coolant�temperature
must�not�exceed�40�°C�/�104°�F.�This�stipulation�must�be�observed�without�fail,�as�otherwise�there�is�a
risk�of�fuel�being�sprayed�back�on�account�of�the�residual�pressure�in�the�high-pressure�fuel�system.
When�working�on�the�high-pressure�fuel�system,�it�is�essential�to�adhere�to�conditions�of�absolute
cleanliness�and�to�observe�the�work�sequences�described�in�the�repair�instructions.�Even�the�slightest
contamination�and�damage�to�the�screwed�fittings�of�the�high-pressure�lines�can�cause�leaks.
When�working�on�the�fuel�system�of�the�S63B44T2�engine,�it�is�important�to�ensure�that�the�ignition
coils�are�not�fouled�with�fuel.�The�resistance�of�the�silicone�material�is�greatly�reduced�by�sustained
contact�with�fuel.�This�may�result�in�flashovers�on�the�spark�plug�head�and�thus�in�misfires.

•
Before�making�any�modifications�to�the�fuel�system,�remove�the�ignition�coils�and�protect
the�spark�plug�shaft�against�ingress�of�fuel�by�covering�with�a�cloth.
•
Before�reinstalling�the�solenoid�valve�injectors,�remove�the�ignition�coils�and�ensure�that

The�S63B44T2�engine�again�uses�two�electric�auxiliary�coolant�pumps,�as�on�the�S63B44T0�engine,
for�the�charge�air�cooling�low-temperature�circuit.�But�unlike�on�the�S63B44T0�engine,�which�had�for
each�cylinder�bank�an�additional�auxiliary�low-temperature�charge�air�coolant�radiator�and�thus�also�an
additional�electric�coolant�pump�for�the�charge�air�low-temperature�circuit�in�each�case,�the�S63B44T2
engine�utilizes�a�pump�for�the�feed�and�a�pump�for�the�return.�The�indirect�charge�air�coolers�are
connected�in�series�to�the�respective�circuit.
Both�50 W�pumps�have�self-diagnosis�and�dry-running�protection,�which�can�lead�to�fault�code�entries
in�the�DME.�If�the�engine�speed�is�increased�by�15�minutes�over�a�period,�the�auxiliary�water�pumps�are
switched�off�and�a�fault�code�is�stored�in�the�DME.�The�expansion�tank�does�not�have�a�coolant�level
switch�and�does�not�automatically�detect�when�the�fluid�level�is�too�low.
If�the�electric�coolant�pump�is�removed�and�then�to�be�reused,�it�is�important�to�ensure�that�it�is�set
down�still�filled�with�coolant.�Drying�out�may�cause�the�bearings�to�stick.�The�upshot�of�this�is�that�the
electric�coolant�pump�may�possibly�not�start,�which�in�turn�may�result�in�engine�damage.
Before�installing,�turn�the�pump�impeller�manually�to�ensure�that�it�moves�freely.

complete�drivetrain,�resulting�in�an�even�sportier�driving�experience�and�reduced�fuel�consumption.
The�power�transmission�capability�of�the�torque�converter�has�been�adapted�to�the�increased�torque
of�the�S63B44T2�engine.
In�the�F85/F86�the�“Idle�coasting”�feature�known�from�the�non�Motorsport�vehicles�is�not�used.
However,�the�M8HP75�supports,�the�“ConnectedShift”�function�which�is�used�in�the�BMW�AG

5.3.2.�Transverse�dynamics�management
Integrated�Chassis�Management�ICM
Integrated�Chassis�Management�(ICM)�is�the�transverse�dynamics�system�network.�This�control�unit
coordinates�the�interaction�between�M�Servotronic�(EPS),�DSC,�VDM,�engine�control�and�Dynamic
Performance�Control.
Dynamic�Performance�Control�(QMVH)
Dynamic�Performance�Control�is�the�further�development�of�the�intelligent�four-wheel�drive�xDrive.
To�date,�the�drive�torque�could�only�be�distributed�between�front�and�rear�axle.�Dynamic�Performance
Control�now�also�allows�a�distribution�of�the�drive�torque�at�the�rear�axle.�The�familiar�rear�axle
differential�is�extended�with�two�variable�ratio�transmissions,�each�comprising�a�double�planetary�gear
and�an�electric�multiple�disc�brake.�The�system�is�already�known�from�the�E71.
The�settings�of�Dynamic�Performance�Control�are�coupled�to�longitudinal�dynamics�management:
•
DSC�On�=�QMVH�Comfort
•
DSC�MDM�=�QMVH�Sport
•
DSC�Off�=�QMVH�Sport
For�further�information�on�Dynamic�Performance�Control,�please�refer�to�the�Technical�Training�Manual
“F15�Complete�Vehicle”�and�“E71�Complete�Vehicle”.
5.3.3.�Longitudinal�dynamics�management
Longitudinal�dynamics�management�is�performed�by�DSC.
DSC�9+�from�Bosch,�as�featured�in�the�F15/F16�production�vehicles,�is�used�in�the�F85/F86.
DSC�9+�has�been�M-specifically�coordinated�to�match�the�M�compound�brake�system.�Furthermore,
DSC�9+�has�been�integrated�into�the�M�Dynamic�Mode�(MDM).�Further�adaptations�have�been�made
to�coordinate�DSC�9+�with�Dynamic�Performance�Control�and�the�M8HP�automatic�transmission.
In�M�Dynamic�Mode�(MDM)�the�control�threshold�of�the�brake�interventions�is�expanded/raised�and�the
engine�power�reduction�by�ASC�is�applied�significantly�later.�This�enables�driver-oriented�dynamic�and
sporty�driveability.
The�“DSC”�driving�dynamics�button�or�the�configuration�in�the�M�Drive�menu�is�used�to�switch
between�DSC�ON,�MDM�and�DSC�OFF.�The�button�obtains�ground�from�ICM�and�sends�back�a�ground
signal�on�actuation�to�ICM.�ICM�forwards�this�information�on�the�FlexRay�data�bus�to�DSC.
Longitudinal�dynamics�can�be�configured�by�the�driver�via�the�M�Drive�menu�in�the�iDrive�or�the�keypad
