    1.5 TSI Engine not restarting from coasting mode.

    I have a situation with my car (2018 Golf Sat Nav 1.5 TSI, DSG along with a number of colleagues who have the same car. That when in the coasting mode the engine doesn't restart when the acceleration is pushed demanding that car is restarted manually - impossible to do on the motorway!
    Car has been off the road for nearly a month after near major accident on the M5 ( colleagues car has been off the road for longer ) VW admits there's an issue with the software and are awaiting a patch for the software.

    Been told that it's safe to drive but not to use the eco function, told them they can keep it until they sort it out as it's a critical safety issue in my book. 6 cars in our fleet have all had the same issue.

    If it was a private car I would of rejected it, VW have provided a hire car at their cost which I will keep until they can remap the software.
    Advice from the dealer is not to use the eco function !
    Any one else having issues?

    Should VW be recalling?

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    Your car spec says 0, only what I've added from your posts.

    Its under warranty keep purging VW to get the software updates.

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Car finally returned after being at the dealers since before Easter. There is now a software update available to fix the error. However car is now coming up with a Power error and visit workshop message. Car will be returning to VW for further work. 6 months in to my first experience of Volkswagen the car has spent nearly 3 months at the dealership.
    VW don't appear to be advertising this software update to a potentially fatal issue, if you have the same engine you will need to request the uodate..

    I take delivery of a 1.5tsi EVO DSG on 12th August. Will be interesting (scary!) to see if it is affected by the same issues...

    Just a thought, perhaps restrict the "scary" aspect by avoiding the coasting novelty and retain full control of your vehicle.
    I continue to get between 49 and 52 mpg (actual) without using any gimmicks, but there again I am very very old..........

    Didn't know that coasting was there or turn off-and-on-able. I have coasting (engine disengaged and idling) in my BMW 220d currently, and it works well, but hard to say how much fuel it really saves. I'm moderately old, so maybe I will turn it off if it causes problems.
