    Default Warning message - 'check injection'

    Hi all, car has dveloped a fault with the dash displaying a message - 'check injection'. When I accelerate I can only get minimal acceleration with each gear only allowing me to accelerate 10mph, so 1st gear gets me to 10mph and 6th gets me to 60 mph. Has anyone had this fault. It's like it's gone into a sort of limp mode. Car is still in warranty.

    Will this need replacement parts or is it another electrical gremlin?

    Thanks

    Its in limp mode, needs the fault codes reading before goings any further. Impossible to diagnose without seeing them first.

    Disconnect the battery for 10mins then restart the car, that usually clears the ECU if the message comes back goto a garage and get it read

    I was told by the Rentech that for a fault to register it must appear 3 times in 3 separate warm up cycles. Allegedly. If thats the case a ECU reset won't help.

    Car was looked at today, problem has occured no less than 20 times. Dealer could not find any stored faults so no problem here is your car back. But?.... there are no faults recorded we can't do anything!

    Take it I just have to accept that the car is completely unreliable? If there are no recorded faults then I presume that's that because they cant look at anything else like the injectors or coil as these don't plug into their diagnostic tool?

    I was assured that it was the Renault technical expert who looked at it, couldn't get an answer if it was the diagnostics he/she looked at or at the parts themselves.

    Unfortuantely we only have 1 dealer in Edinburgh and there is no where else I can think of to take it and remain in warranty :/

    Tried RUK Customer Services who were really helpful and no problem to deal with but don't know what they are going to be able to do, they said they would try contacting the garage.

    Also had a loom replaced for the back reg plate light a while back as it had melted and now since the repair I'm going through rear brake lights at the rate of knots as they keep blowing weekly or monthly. Again, no problem can be found !!!! (twice been looked at for this)

    Any suggestions?

    The problem of your back reg light going is a comon fault and there is a kit to fix it. This used to happen to mine until the dealer got it sorted under warranty.
    There are loads of renault garages in Glasgow, you should take it through there.

    Has your car been mapped?.

    I had that problem, few months after I bought car... "Check injection" message and "limp" mode, it pulls good, but only up to 4000 rpm,or less, sometimes. Diagnostic tool didn't help at all (no faults), car was in RENAULT garage for 18 days.
    Finally, they told me that the problem was with "engine management injection computer" and some "turbo valve" (placed under the windshield, on the firewall). They replaced it, it was obviously new part ("engine management injection computer"), placed just behind battery...
    It was done under warranty, so I don't know price... I just can't imagine how expensive it is... I didn't dare to ask.

    escobar... if you are looking for a Renault specialist in Edinburgh instead of a main dealer (for servicing etc)... then try Rentec in Telferton Industrial Estate (that is the Industrial Estate opposite the Land Rover garage down Seafield). I used them instead of the main dealer when I was getting my Hub/Swivel bearing sorted out. Ex-Renault tecnicians that decided to set up on their own.
    Might not be able to do warranty work for you though... but might be worth a call?

    I reckon N75 Boost Pressure Solenoid or one of Boost Pressure sensors, either on the intake or before the throttle.

    Do these people even know how to use THE CLIP (Renault diagnostic tool)???
    Its impossible that a CHECK INJECTION wont leave a fault on the ECU, ive checked this kind of fault plenty times on the CLIP and its always there and it tells you where/what is the problem.

    Other then having a hand come out of the laptop and do the job for them, they will always say "There is nothing wrong, here is your car back"....bloody idiots!!!
