2006 2010 BMW 2 Series E90 Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The E90 chassis code designates the fifth generation BMW 3 Series sedan produced from 2005 through 2011. The E92 coupe variant launched slightly later for the 2007 model year alongside the E93 convertible and E91 touring wagon platform. Collectively referred to under the E9x umbrella, this generation represented a significant technological leap for BMW featuring aluminum intensive front and rear suspension construction, electric power steering replacing the previous hydraulic system on many variants, and the revolutionary iDrive infotainment system integration.
The E90 generation was powered by an exceptionally diverse engine lineup ranging from the entry level N43 four cylinder in European markets to the legendary N52 naturally aspirated inline six serving as the backbone of the range, and the twin turbo N54 inline six in the 335i models that earned widespread acclaim for its tuning potential and performance output. BMW M developed the high performance E92 M3 with the S65 naturally aspirated V8 engine revving to 8400 RPM.
SERVICE AND REPAIR SCOPE:
Comprehensive engine service covers the N52 inline six with Valvetronic variable valve lift system diagnosis including eccentric shaft position sensor adaptation, Valvetronic motor removal and installation with intermediate lever bearing inspection, and intake VANOS variable valve timing solenoid testing with activation commands through diagnostic scanner. Carbon buildup cleaning procedures for the direct injection N54 engine intake valve walnut blasting technique are included with special adapter tool part references.
The N54 twin turbo engine turbocharger wastegate rattle diagnosis covers the wastegate pivot shaft wear assessment and replacement with updated bushing components, high pressure fuel pump HPFP replacement procedure with fuel system depressurization steps, and fuel injector index value coding and adaptation entry using ISTA diagnostic software.
Six speed manual transmission GS6 service includes clutch replacement with concentric slave cylinder electronic connector handling, dual mass flywheel free play measurement with angular deflection specifications, and mechatronic module for SMG automated manual gearbox actuator seal assessment where equipped. The ZF six speed automatic GA6HP service covers the mechatronic sleeve seal replacement to prevent the common fluid leak between transmission and bell housing, valve body solenoid pack removal with connector release procedures, and internal conductor plate replacement with updated connector design.
Suspension repair includes the aluminum multi link front strut replacement with thrust arm ball joint service, rear five link arm bushing replacement with full hydraulic bushing filling procedures, and electric power steering rack assembly replacement with steering angle sensor initialization. Brake system documentation covers Dynamic Stability Control DSC system hydraulic unit bleeding with ISTA service function, brake pad wear sensor circuit verification, and rear caliper parking brake spindle wind back with electronic motor retraction procedure on EPB equipped models.
TECHNICAL SPECIFICATIONS:
Manufacturer: BMW AG
Chassis: E90 sedan, E92 coupe, E93 convertible, E91 wagon
Engine options: N46 2.0L inline four, N52 2.5L and 3.0L inline six, N54 3.0L twin turbo inline six, N53 2.5L inline six direct injection, S65 4.0L V8 M3
Transmission: 6 speed manual GS6, 6 speed automatic ZF GA6HP, 7 speed M DCT M3
Drive: Rear wheel drive or xDrive all wheel drive select markets
Wheelbase: 2760 mm
Curb weight: approximately 1450 to 1650 kg depending on engine and body style
DIAGNOSTIC INFORMATION:
Engine oil consumption diagnosis on N52 engines involves valve stem seal oil leak testing using borescope inspection through spark plug tube, crankcase ventilation oil separator diaphragm rupture verification by removing oil filler cap at idle and checking for excessive vacuum suction, and piston ring land carbon assessment requiring cylinder head removal.
Engine overheating with N52 engine traces through electric water pump operation verification using ISTA activation test, thermostat integration with pump housing replacement since they are a combined unit, and cooling system bleeding procedure with electronic bleed mode that cycles the pump at various speeds to eliminate trapped air.
Transmission mechatronic leak on the ZF 6HP automatic is identified externally by fluid weeping from the transmission engine junction area. The internal sleeve between the mechatronic module and aluminum transmission housing is the failure point and requires pan removal and sleeve extraction tool for service.
ILLUSTRATIONS AND DIAGRAMS INCLUDED:
N52 engine sectional view highlighting Valvetronic eccentric shaft and intermediate lever arrangement, N54 twin turbocharger intercooler routing with charge pipe connection detail, ZF 6HP automatic transmission mechatronic module exploded assembly showing sleeve seal location, multi link front and rear suspension component identification diagrams, DSC hydraulic unit brake circuit schematic with valve block detail, iDrive CCC and CIC head unit wiring harness routing showing MOST fiber optic ring topology, and EPB electric parking brake rear caliper motor release and installation detail with tool engagement diagram.
COMPATIBILITY:
This manual covers the 2006 through 2010 BMW E90 generation 3 Series including sedan E90, coupe E92, and all derivative body styles. Content applies to the 323i, 325i, 328i, 330i, and 335i models with N46, N52, N53, and N54 engine platforms across rear wheel drive and xDrive configurations. Select high performance procedures reference the E92 M3 S65 V8 engine.
