    S4 Starting Issues

    Guest-only advertisement. Register or Log In now!
    The other day I got in my S4 to drive it for the first time in a couple weeks. When I first started the car it started up fine, took it down the road roughly 3 miles to grab some dinner. When I got back in the car about an hour and a half later it would not start. It turned over and cranked but would not fire up. With being so close to the house we got an uber back I grabbed some tools and my scanner to start my process of elimination on what the issue could be while I waited for a tow back to my home. Got back in the car to pop the hood and thought I would give it another shot before I started digging into what could be going on and surprisingly enought it started right up with no hesitation. Once again I got in it today to see if it would start and no issues. I was wondering if anyone has had this issue and found a remedy for it? I know that the celluloid in the starter on theses cars tends to go out.

    Thanks in advance for any help

    My b6 was doing something similar a few months back. The only difference was my car wouldn’t fire up when it was warm. Happened to be the crank sensor

    Did you pull any codes?

    My first bet would be crank position sensor as well.
