Hello, have been C4 owner for a few days and have looked around in the forum for MP3 player connection to my RD4 and have also been well informed. However, I now have a problem to which I could not find an answer. I have a C4 style, so without rain sensor. I can put the windscreen wiper either on the positions off, interval or continuous wiping level 1 / 2. The interval circuit is according to the manual according to the speed, but the If I turn off the engine in the interval circuit (i.e. park) and then continue driving, the lever stands at interval, but the windscreen wiper just doesn’t start wiping. I thought I would drive 100-200m then it will start, but no, nothing is happening at all. I have to turn around at the wiper lever again, either on off or permanent wipe and then back into the interval circuit again. Is that really what I want or is going to do? What not? Thank you for your contributions! Bye
