108 pages. 18 sections. 15 figures. Symptom first, then the test that proves it, then the value to set.
Four parts, 18 sections, from the first symptom to the pre-purchase check.
Three of the manual's 15 figures, as they appear in the book.
Every value traced to a page in BMW factory data, Bentley or Haynes. None from forums.
BMW factory information: BMW E30 factory repair manual, and BMW TIS tightening torques. Bentley: BMW 3 Series (E30) Service Manual 1984–1990. Haynes: BMW 3- & 5-Series 1983–91, UK edition.
