Frequently Asked Questions
Does this manual cover the turbocharged 924 Turbo (931)?
Yes. The 924 Turbo, internally coded 931, is fully covered including the KKK turbocharger assembly, boost control, intercooler (on later models), and the uprated braking system unique to that variant. All torque specs and service intervals specific to the turbocharged drivetrain are included.
Is the 924S with the 2.5L engine included?
Yes. The 924S produced from 1986–1988 used the 2.5L inline-four shared with the 944, and this manual includes the specific procedures for that engine variant, including its different fuel injection calibration and exhaust system routing.
Are Bosch K-Jetronic fuel injection wiring diagrams included?
Absolutely. Complete wiring schematics for both Bosch K-Jetronic (CIS) and the later L-Jetronic electronic fuel injection systems are included, with connector pinouts, wire color codes, and step-by-step diagnostic procedures for fault finding.
