Character
G9T
"Laguna II, Vel Satis. Common rail successor to G8T. Injector failures. DPF on later models. Turbo actuator. More complex = more failure points. Vel Satis reputation doesn't help."
D4F
"Clio/Twingo/Modus. Tiny but tough. Timing chain on D4F (good). Throttle body failure. Idle issues. Simple and cheap. Perfect city car engine."
