    Default Abnormal engine running.

    Hi All,

    I bought a brand new Opel Vectra Caravan, 19 CDTI, 120HP one month ago.
    I have 3500 km today.

    My car engine is not running normaly I think. I will try to describe it.
    It looks like the engine is switching between two running modes.

    1. Drive on straight road. Speed 60km/h, speed gear 4, instant consumption around 5 liter.

    2. The same road , same situation, but the noise from the engine is bigger, and instant consumption is around 10 liters....

    My car is switching between this two modes too often. No check light is luminary.

    Had somebody the same problem ?

    Thank you

    Sounds like it could be the DPF

    despite the manual, there is no light when the DPF is recycling (it should only come on when the DPF is full and cannot clean itself, but even that does not happen I think)... and there is no smoke visible neither...
    however only 3500 km and you had this often ?! do you do a lot of city traffic? next time it happens, don't stop but go on a motorway and drive until it stops... otherwise take it back to your dealer
