How to Help

There are several ways to contribute to improving this repair manual archive.

Feedback and corrections: Providing feedback to improve the quality of procedures and technical articles is the most valuable contribution. This includes pointing out errors, submitting ideas for new procedures, or submitting procedures for inclusion. Even rough handwritten notes are useful — formatting can always be handled separately.

Photographs: Procedures that lack photographs benefit greatly from illustrative images. If you use a procedure that has no pictures, or you want to see more detail in an existing one, taking a few photos during your own repair work and submitting them is a meaningful contribution.

944 Air Conditioning — Technical Data, Refrigerant & Service

Factory data for the 944's R12 air-conditioning system — the refrigerant charge, the compressor oil fill, the rupture-seal and coupling-power figures, and the compressor/condenser/line tightening torques — followed by a concise evacuate → flush → charge service overview with its vacuum and pressure targets. This is an R12 system, so handle the refrigerant only with proper recovery equipment. Pressures switch between bar and psi and torques between N·m and ft·lb.

944 Anti-lock Braking System (ABS) — Service, Sensors & Torques

Service data for the optional Bosch three-channel ABS (M593) fitted to the 944, 944 S and 944 Turbo — the system layout, the wheel-speed sensors and their fixed (non-adjustable) air gap, hydraulic-unit and relay service notes, the bleeding rule, and every ABS-specific tightening torque the factory states. The sensor air gap is a design feature and is not set on the car; bleeding follows the same procedure as a car without ABS.
