Why is my Volkswagen suddenly not starting?
Alternator—A bad alternator can prevent your battery from charging, leaving you with too little power to start your car. Starter: A faulty starter can draw more power than needed, draining your battery. Spark Plugs—Your spark plugs have a lifespan of about 100,000 miles, so problems are rare. The most common reason a car won’t start is a dead battery. A dead battery can be caused by leaving the lights on overnight, a faulty charging system, or simply an old battery that needs to be replaced.
What is the TDI issue with Volkswagen?
The agency had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate their emissions controls only during laboratory emissions testing, which caused the vehicles’ NO x output to meet US standards during regulatory testing. Volkswagen engineers informed management that they could not make diesel models meet new federal emissions standards — which required a 94 percent reduction in nitrous oxide tailpipe emissions — within the allotted development time and budget.The agency had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate their emissions controls only during laboratory emissions testing, which caused the vehicles’ NO x output to meet US standards during regulatory testing.
