Executive Buyer's Report
Is the Porsche PDK Transmission (7-Speed / 8-Speed) Reliable?
Risk Score: 5/10
The Verdict:
"The Porsche Doppelkupplung (PDK) is the benchmark for dual-clutch reliability, often lasting over 100,000 miles even under rigorous track use. However, when it does fail-typically due to the unserviceable internal distance sensor-Porsche dealers will only quote a full $20,000+ replacement. Buying without documented fluid changes is a massive gamble."
