Hello to the round, I wanted to inform myself what can be done with a C4 Grand Picasso 1.6 HDi, which only causes problems. The good piece has now just 13.000km on it and is 8 months old. Can you help me???? List of problems: 1. Quitting the brakes when driving backwards after 3.000km 2. Noise (cracking) of the right front axle when driving curbs (5.000km) 3. Whistling of the blower of the air conditioning (change of the fan) after 9,000km 4. Whistling occurred again after 10.500km. Was again one and upgraded 5. Quitting the brakes when driving back at the time 6. Whisting in the area of the engine room. Could not be determined by the dealer yet?!! Can you help me? Greeting Sven Sven
