    Default Cruise control for 2004 307 Xs Hdi manual wagon

    Great little car, but the cruise control is a waste of time - it drops 10km then surges back to the set speed.

    Does anyone know if there is a firmware upgrade or any other resolution (even a replacement cruise system)

    Also, can you tell me where to go , in Melbourne to get this fixed

    Would appreciate your help

    Could be the BSI with a gremlin or a poor fuse contact.
    I fixed a BSI fault by removing and repositioning the fuses.

    It may be worth a try.

    Maybe the same problem.

    I have a 2010 207 auto where the cruise control sometimes would not work, then eventually did not work at all. The problem was finally diagnosed as a faulty brake switch (intermittent fault, of course). Apparently the computer senses an error caused by the poor connection to the brake switch - and shuts down the CC as a precaution. New brake switch, computer reset, problem gone. You probably have the same standard brake switch on the 307? maybe.

    BTW - the switch fault had no effect on car safety.

    Any dealer could do the fix and may have the part there else ordered in. Got mine done at Justin Fisher Automotive Deepdene - same few days probably.

    You could put up with the problem by avoiding the cruise control of course and ring ahead to ensure the part is there. Only takes an hour or so.

    I'd say it's an issue with vacuum, boost or throttle response.

    A faulty brake switch would stop the cruise working at all (ie. make it trip off or not engage at all), not make it lose 10km/h before getting back to the set speed. I'm not sure if that model 307 needed some kind of vacuum pod to control the CC, but with an electronic throttle, probably not.

    I assume this is a reasonably "low-spec" non-intercooled 2.0 5sp? Remember there is only 66kW to start with.

    I'd be looking for boost leaks or perhaps a partially blocked cat. Something you may not notice driving "manually", but shows up under cruise control.
