BMW 3 E30 History
Some BMW 3 E30 Wiring Diagrams are above the page.
E30 first appeared in January 1983 in a single version of the 2-door coupe.
Only a year later, in January 1984, buyers had the opportunity to choose with the advent of the 4-door sedan, which at once greatly increased the popularity of the model. In 1986, the E30 convertible went on sale. And only close to the end of the production of E30 Bavarians pleased generalist.
True, the luggage compartment could not boast a significant amount, but the car looked just great. Another rare modification - the all-wheel drive model 325iX - borrowed the transmission from the all-wheel drive "five" in the back of the E34. Produced and diesel versions of the sedan.
