I have a 2008 GTS with 55k miles on it. For the past couple of months the GTS generally cranks slowly but starts up on the first try when the engine is cold or has been sitting idle for a couple of days. But when the engine is hot, it take 2 tries to get it started up.
With a hot engine it could take up to 4 or 5 cranks to get it started. Last night i was out and about and stopped by the grocery store and 15 mins later it wouldn't start up. Waited about 2 hrs hoping it would start up on a cool engine but it didn't. i got desperate and decided to Jump start it with another car battery c
