TSP Accumulators Correction actions Design correction by TSP FEM validation by MDT MDT assistance during testing MDT supports QA/QC of production All 4856 pcs TSP 10L accumulators are being exchanged, around 4130 pcs are exchanged presently < 8 >
MPC/MPC10 Orion case < 9 >
MPC/MPC10 Orion case Case story Problem: Increased failure rates from one MPC/MPC10 manufacturer Data collection: Investigations and auditing Root cause: Fluxing and soldering processes affected Corrective actions: Temporary production stop. Changes in production process and QA/QC Verification: > 4000 units produced return rate ~ 1% < 10 >
EC MOP Sticky Touch Issue Issue: Touch pointer sticks Root cause: Failure of glass plate separation Corrective actions: Improved bonding Preassembly tests Verification: 0.5 % to 1.4 % failure rates after corrective actions < 11 >
ELFI / ELVA / FIVA Status: Sandwich filter has nearly eliminated shop test / sea trial problems. Super fine filter introduced for new orders from primo 2015 < 12 >
Inductive Sensors For fuel booster and exhaust valve position Claim rates are relatively low (<1.5%) Our work continue to reduce to target of 0.5 % or better. Sensor specification tightened with more strict reliability, environmental and dynamic characteristics demands. More strict approval procedure. < 13 >
