What are some of the vw Passat push button start problems?

If You're finding that the push button won't start on the Volkswagen Passat, which is rare, as this is a pretty reliable mechanism, the first thing You should investigate is whether Your car's battery has become drained. After You've checked that, the next thing is to verify You're properly pushing down on the brake pedal. If it's not a simple thing, then, it's possible the switch is broken. These do become worn out over time and with use. The part itself is going to run about $120, and if You get it fixed at a VW dealership, You can usually expect to pay for an hour of labor, about $150.
