BSM module was replaced on Wednesday and everything works fine now. £150 with fitting.

Some kind of control unit needs replacement - around £170

Maybe it's coincidental , but before this wiper malfunction i could sense strange feedback when turning the steering wheel - something like a noiseless klunk/stuck every 30 degrees on both sides, but now turning is completely smooth without any vibration. I also noticed when i put the lever in highest speed while the ignition is turned off and then start the car, the lever is completely without any response regardeless of position. If I put the lever back to off and left the car turned off for 15 mins, the lever starts responding in highest speed again and pulling the lever down on auto can be seen on display again (but without any reaction from wipers)

Hello Yesterday I've encountered a problem with my c4. I haven't used it for 3 days and when I started the car I noticed the wipers are only working on highest speed. I have 2008 C4 with auto wipers/headlights. Symptoms: - wipers work only on highest speed - when I switch from highest to lower speed the wiper just stop without returning to idle position - washers work fine - when I push down the wiper lever to auto position - display says something like (basic text display) "automatic wiper mode - active - automatic wiper mode" So it repeats automatic wiper text line beneath telling weather it is active or inactive I tried to reset BSI but everything remained the same I tried to remove shunt fuse for 20 mins but everything remained the same. I went to citroen dealership but they couldn't find any errors on Lexia and told me to return on Monday because on Saturday there aren't any technicians working Only thing i didn't try is to disconnect comm 2000 i try to reset it (i don't know the procedure for that) I am trying to avoid paying for expensive comm 2000 part or something like that if it is possible to solve anything with resetting or something similar Does anyone have an idea what could this be?
