No one has explained why the X3 diesel had such high emissions and the ICCT wouldn't comment on the Auto Bild report. But the mag has issued a clarification asserting that in spite of the excessive emissions, there is no evidence BMW engaged in regulatory subterfuge. Every other BMW vehicle ICCT tested was within compliance, but the organization's report from October 2014 - that no one paid attention to - found that nitrogen oxide emissions in 15 vehicles it tested averaged seven times the European limit.
The brand's stock is still suffering from the taint. It dropped almost ten percent the day the report came out before rallying to close at five percent down. But on Monday BMW stock closed at 84.01 euros, and as of writing on Friday it's still trying to fight its way back above 80 euros. With so many people still just trying to find out how widespread the the issue is, and trust rather low, it's likely BMW won't be the one dragged down, fairly or not.
