Thread: Car keeps cutting out / Snowflake

  1. #1

    Default Car keeps cutting out / Snowflake

    Good afternoon,

    I have 2004 C2 Sensodrive.

    On odd occasions, the gearbox changes down the gears quite fast and goes into snowflake mode and cuts out.

    Sometimes, you hear a peep, and the car will continue to drive until you stop, and it stalls / cuts out with a snowflake.

    The mechanic has reset stuff previously and says it's ok, but it keeps happening.

    He gave me a temporary fix while out driving, which consists of taking off positive battery cable for a few minutes, reconnecting, turning on ignition with foot on the brake for a couple of minutes.

    I hear clicking and clunking, and then the car starts.

    I have no knowledge of car mechanics, but I bet one of you fine folk can point me in the right direction ?

    Thanks.

    You need to get it connected to dealer level software (no general diagnostic software will work correctly) "Lexia" is the name it will check sensors on gearbox, It could also be loosing a signal from another ECU such as ABS.
    Try switching to manual mode and change up manually (it should still change down on it own) using stick or flappy paddles.

    You would be better trying to find a small independent Citreon specialist (make sure he has proper Citreon diagnostic gear) the problem with dealer is they will just want to put new gearbox on its down to them warranting there work.

    So.... Citroen hooked it up to there equipment. I went on Friday to get an update.
    some very expensive cable, lots of other stuff.

    All this for a mere 1800 Euro.

    More than the car is worth !

    I will take your advice and find a local deal with Citroen gear.

    Thanks again.

    Did they take money off you in return for a service? In this case to diagnose and quote for a repair on your car? Did they provide you with a written quote of the fault and total cost of parts and repair? If so can you tell us what the quote said? You are entitled to know what they believe the fault is and what they believe the rectification is. THEY CANNOT CHARGE YOU TO SIMPLY REPLACE PARTS UNLESS YOU DIRECT THEM TO DO SO!! You are paying them to FIX the car, not randomly replace parts! Did they provide this service for free? If so, then you got your money’s worth! If they charged you for a service (to quote for repairs on the car) and did not provide you with said quote then they are in breach of consumer laws. To TAKE money from someone without providing goods or service is called ROBBERY! However, if you GIVE money to someone…well that’s your choice.

    Thanks for your reply ozVTR,

    I asked Citroen to reset and update gearbox software .

    This was advice from a local mechanic as a possible cheap fix.

    They hooked it up and wanted to replace some or all of the clutch, cat converter, and other stuff. I have the full itemised quote at home, so will update asap.

    I paid 70 Euro for the diagnostic.

    My regular mechanic said that this is what main dealers do, as they don't want to do a quick 200 Euro fix, and you keep taking it back every month.

    I have had sensors and wires cleaned, and the problem has stopped. It will come back.

    To summerise, What I went in for, and what they quoted me are two different things, but their take on fixing my problem.

    I am in Spain, and consumer laws can be difficult to enforce.

    Thank you for your reply, and I will come back soon with the itemised quote.

    Cheers.

    It's hard to diagnose a single probable cause from the symptoms you have given.
    It's possible a failure of the gearbox actuator would cause the car to stall but that would be a "hard" failure and a system reset would not usually clear it. A worn clutch would cause an error (snowflake of death and limp mode) and you could temporarily clear it but I can't see how it would cause the car to stall.
    Sensodrive errors can prevent the car from starting and cause erroneous gearbox performance but I cant see how it would stop the car while it's running. Again some form of clutch actuator failure is the only thing I can guess if the car is stalling but that assumes there is only one failure.
    If they have given you a print out from the LEXIA reader that would be great. If they only gave you their "opinion" of what is wrong...well that's better than nothing.
    To be honest 70 euro for an update and system diagnosis sounds about right from a Citroen dealer. Not bad for about ten minutes work, Eh? Other guys on this forum will tell you they have paid about the same money for about the same service, so don't feel ripped off. The real question is; will their diagnosis fix the car and is all of their quote necessary?

    I tried many thing over the past two years to try to solve a similar actuator issue.

    I ended up changing the clutch actuator and everything work flawlessly since then.

    I let you have a look at this topic : http://www.c2club.co.uk/showthread.p...-shift-gear-up

    You can't do it by yourself but if you go to Citroen that will cost you more than the car itself. You need to find an independent mecanician with Lexia.

    The clutch actuator cost around 300 euros brand new on internet VS more than 700 at citroen dealer...
