Hi All,
I've got a '17 GTI with around 53k miles on it. It recently had a catastrophic clutch failure (pedal just stuck to the floor while driving in heavy traffic), and while I was unfortunately not able to get any help from the dealer or VoA, at least the car has a brand new clutch and flywheel (that's how catastrophic the failure was...).
Since that repair ,the car has only been driven 100-200 miles. It would always start on the first button-press, but I noticed once that on the first press it did nothing, but it started on the second. Then a few days later I went to start the car, and nothing at all. Due to this failure to start, I accidentally left the car on but not running for a few hours, but all that was running were the tail lights, internal instruments, and the fan on low. So I checked the battery, and the voltage was low. My charger said it was very low-10ish volts, but I put it on a trickle-charge anyhow.
I assumed that either the battery was toast, or the alternator went and killed the battery, so I wanted to just start the car and measure the voltage across the battery terminals to see if the alternator was charging the battery. With the battery fully charged, I got exactly the same result: the car just turns on and the engine does nothing at all: it doesn't try to turn over.
Wondering if the battery was so toast it couldn't provide any cranking current (or anywhere near enough for the starter to move), I changed my charge over to its boost setting. Same result: the engine won't turn over at all.
I connected the VCDS and did a full auto-scan of codes. I'm a beginner with the VCDS, but the only code that seemed relevant to me is:
So I'm trying to figure out what to do next. I have only limited time to debug this, but thoughts I've had:
Could there have been some kind of immoblizer interlock that came on when the battery voltage dipped so low?
Could there be a problem with the starter? Bad connection...up to and including it died when being removed and replaced during the recent clutch job?
Thanks for any ideas!
