Hi there,
I'm new here and first of all sorry for my English!
I drive a Berlingo (B9, orga number 12049) and have problems with the original built in cruise control. I bought it from private and the cruise control haven't ever worked.
The problem is that most of the time it shows "--" if I try to switch it on so it seems that it doesn't know the current speed. When I drive arround 80 km/h or faster mostly it knows the current speed and sometimes I'm able to switch it on but it switches off again after a few seconds. If I can switch it on and press the accelerator pedal down so that I drive faster than the cruise control is set to it will stay switched on for a while and I can even go off from the accelerator pedal and it holds the current speed for maybe 10 or 15 seconds the it switches off again. If it works for a few seconds I can even increase the speed with the cruise control button, when I stop accelerating it usually switches off again immediately :brickwall:
There are no faults shown in any control units.
I know that's not the engine control (Citroen number 1320) because I replaced it already. I also replaced the switch at the steering wheel and the two sensor wheels on the back (left one was damaged) and the sensor back left side. I cleaned the front sensor wheels. Furthermore I replaced the switch at the clutch pedal and the one on the break pedal. I meassured contacts between PSF, clutch pedal switch and engine control (6783X, KM73X) and between PSF, break pedal switch and engine control (CM21X, 7309X).
I wasn't able to meassure accelerator pedal, it seems that it doesn't contain just simple potentiometers so I have no idea how I can meassure it?
Is there a possibility to investigate what causes the cruise control to switch off again and again? Maybe with Lexia or so?
Thanks a lot for any help!
By the way, the speed limiter and ESP is working fine!
