My VW EOS won't start for the 3rd time in the past 2 months . During the first time, thank God I was at home. The car would click but would not start. The dealership replaced the battery. A few weeks later, the car would not start again. Same symptoms - clicking noise but this time would start but would cut off immediately. The alternator light appeared in red on the dashboard. Unfortunately, the dealership could not replicate the issue because after 20-30 min of sitting idle, it would start. Fast forward to today, my car would not start again. Same symptoms - clicking, start and immediately shut off; alternator light on. After sitting idle for 30 min, the car finally started and I was able to drive it home. What is wrong with this car? And why does this problem appear intermittently like this?
Ask the dealership test the alternator.
The alternator is like a generator for your battery.
If it has failed, then your battery won't be recharged as your car drains it - and will quit working.
If it is the alternator, and they replace it, have them connect the battery to a battery charger at a 'slow charge' to bring your battery back up to a full charge.
