Porsche 718 Workshop Cases Malaysia — 4M Car Care
Real 718 cases: 982 Cayman 2.0L 63,000 km rough cold idle — carbon buildup confirmed via borescope. Walnut blast through intake manifold idle immediately smoother. 982 Boxster S 2.5L 55,000 km PDK cold shudder — fluid never changed. Fluid flush + PIWIS re-adaptation resolved. 982 Cayman GTS 4.0L 82,000 km rear diff whine — diff fluid dried out. Fluid change noise eliminated.
Porsche 718 Workshop Case Studies
- Case: 2019 718 Cayman S — owner skipped PDK fluid at 60,000 km. At 85,000 km, shudder in D at 30 km/h. PDK fluid + filter change resolved it: RM 750. Mechatronic unit spared.
- Case: 2020 718 Boxster 2.0T — rough idle and 15% power loss at 72,000 km. PIWIS showed no codes. Walnut blast performed: heavy carbon on all 4 intake valves. Power fully restored, idle smooth.
