    Is there a way to exend the glow plug on time on cr140 TDI using Vagcom?

    Hi everyone

    My car is a 2009 Jetta with a 2.0L CR140 TDI. I'm going to be enjoying the colder northern climate in Alberta for the next couple months and last time I was there had some issues
    with it not starting properly. Ive installed an 800 CCA battery and freshened up the starter and it now cranks over noticeably faster.

    I have VCDS (Vagcom) and I was wondering if I can go in and increase the glow plug on time?

    If so, what are the steps to follow?

    Thank You

    Allen

    First thing is to post an autoscan.
    Second, I'm for 99% sure there are no coding or adaptation available to tweak the glow time.
    An old-school method - switch ignition on for approx 20sec (do not start), switch it off, switch on again and start after some 15-20sec
