Here in Norway we actually have quite strong consumer rights, but only to have the original fault repaired, and only within the first two or five years depending on how long a product is expected to work (they actually put mobile phones in the five year category, simpler and cheaper electronics are in the two year category) and we have always considered the rights in Norway as better than in the US, but replacing an idler pulley is nothing for BMW, worth taking a risk for. Normally the customer will be happy enough after having the fault repaired. A major lawsuit in the US where they can lose millions however... VW set aside an insane amount of money for the diesel lawsuits, but I believe they expected to spend 90-95% of it in North America, even though the numbers of affected cars are higher in Europe...
