1988-1994 BMW 7 Series Service Repair Workshop Manual PDF

VEHICLE/EQUIPMENT INTRODUCTION:

The second-generation BMW 7 Series, internally designated E32, represents a landmark period in BMW luxury sedan engineering from 1988 through 1994. This was the era when BMW firmly established itself as the leading producer of premium European sports sedans, competing head-to-head with Mercedes-Benz S-Class and the emerging Lexus LS400. The E32 7 Series introduced several technological innovations that would define modern luxury automobiles, including the first BMW V8 engine in decades (the M60 3.0L and 4.0L introduced in 1992), advanced electronically controlled suspension systems, dual-zone automatic climate control, Park Distance Control, and the onboard computer system. The initial engine lineup at launch featured the smooth inline-6 M30 engine in the 730i and 735i, followed by the flagship 750i introduced in 1988 with the legendary M70 5.0L V12 making approximately 300 horsepower, making it the first V12-powered sedan since the pre-war era. The E32 chassis featured double-joint spring strut front suspension and multi-link rear suspension, providing the refined ride quality expected of a flagship luxury sedan while retaining BMWs signature driving engagement. The body structure employed sophisticated crumple zone engineering and extensive galvanization for corrosion protection. Electronics including the EWS immobilizer system, electronic engine controls, and automatic transmission management were cutting-edge for the late 1980s and early 1990s. Today, the E32 7 Series is gaining recognition as a modern classic, with well-maintained examples appreciated by enthusiasts who value the analog driving feel of this generation before excessive computerization took over automotive design.
