  • Eco Stop Start problems - stalling at lights

    Hi - any help please

    I have a 4 year old diesel Insignia and up to now the stop-start (eco) function has worked (except for not always cutting the engine if a lot of electrical appliances (heater/air con etc.) are in use.

    But twice in the last couple of months I have been at lights and the engine will NOT restart, it just whines and whirrs. But the first time it broke down after a 3 hour wait for Green Flag is started OK.
    And now it broke down yesterday at lights, the vehicle was recovered last night, just spoke to the garage and they said it has started first time this morning.
    Both times have been after a motorway drive of about 10 miles followed by urban driving with traffic lights.
    Any ideas?
    Our garage said the first time that they thought the Diesel Particulate Filter had gone into regen mode on the motorway, but then the sensors said it was too hot to start once you are stopped at lights. Hence failure to start.
    Anyway - any ideas?

    If it was doing a regen it wouldn't cut out under stop/start conditions till regen was complete
