SUBJECT
Fuel Injection and Induction System Cleaning
MODEL
SITUATION
Deposits found in the injection and induction system may cause the vehicle to experience a variety of drivability complaints, eventually leading to
the Service Engine Soon lamp to be illuminated. Some of the possibilities are listed below.
Fuel Injectors
Deposits at the fuel injector's tip can impact fuel flow, disturbing the air/fuel mixture ratio.
Symptoms are the following: Hesitation or stumble during acceleration, or even loss of power; poor fuel efficiency; increased emissions of HC and
CO; and "Service Engine Soon" lamp illumination due to misfire faults, or lean mixture adaptations.
Intake Valves
2010 BMW 650i Convertible (E64) V8-4.8L (N62TU) Page 446
Deposits at the valves and on the intake manifold ports can absorb fuel during the warm-up phase, leaning out the air/fuel mixture ratio. Carbon
buildup may disturb the mixture flow at low throttle conditions and/or idle speeds.
Symptoms are the following: Poor drivability; loss of power; unstable and/or rough idle; increased emissions of HC, CO and NOx; and "Service
Engine Soon" lamp illumination due to intermittent misfire faults.
Combustion Chamber
Combustion Chamber Deposit Interference (CCDI) occurs when there is contact between carbon deposits on the piston crown and the cylinder head.
The noise can be confused or misdiagnosed as a ping, knock, or other noises that could indicate a mechanical failure. CCDI occurs first as a cold
start noise that can fade as the engine warms to operating temperature. The noise will reoccur at the next cold start. As deposits build, there is an
increase in compression temperature that may cause pre-ignition detonations.
Symptoms are the following: Knocking; pinging; run-on; poor acceleration; octane requirement increase; increased emissions of NOx; and engine
idle speed surges.
Depending on the manufacturer, fuels may contain various additives such as: oxidation and corrosion inhibitors; metal deactivators; emulsifiers; and
anti-icing agents and dyes. In addition, they are required to include some form of an intake system deposit control package. Unfortunately, not all
fuels are created equal, and some additive packages are not effective enough to maintain the integrity of the intake systems in high performance
engines, or engines operating under severe environmental conditions. Even worse, the intake system deposit control additives in some fuels may
actually contribute to the combustion chamber deposits accumulation, and to the problems associated with those deposits, i.e., knock, run-on and
increased emissions of oxides of nitrogen.
To remedy these complaints, the BMW Group has developed a new special tool and cleaner concentrate to clean the fuel injectors, induction system
and combustion chamber of harmful deposits.
Note:
The fluids and tools described in this Service Information bulletin are the only BMW approved items that can used to clean the fuel injection system,
induction system and combustion chamber. Using non-approved fluids or tools can lead to premature component failure and will not be covered
under Warranty.
