Every control module on the 1981-1989 Porsche 911 Turbo — where it lives, replacement time, and what it takes to program a replacement.
Instrument Cluster (Kombi)1.5 hr R&Rno coding
📍 Dashboard behind instrument panel
⚠️ Primarily analog with limited electronics. Odometer is mechanical; no mileage programming exists.
Digital Motor Electronics (DME)1.2 hr R&Rno coding
📍 Engine compartment, left rear near battery
⚠️ 1981-1983 models use Bosch K-Jetronic mechanical injection with no DME. DME introduced 1984+ with Motronic system. Early DME uses EPROM chips; replacement requires no coding but may need EPROM swap for calibration.

📍 Front luggage compartment, left side
⚠️ Optional equipment starting 1987 model year. Bosch ABS 2 system. No coding required; self-calibrates on first drive.

📍 Center console
⚠️ Blaupunkt or Becker units. May require radio code entry after battery disconnect.
