Is this a diesel only thing or is it possible they pulled the same trick with petrols?

Looks to be a one off and more then likely a fault with the x3 no rigging software was found and a variety of other bmws were tested and well within limitsQuote:

The main problem imo is the limit is too strict in the first place they are pushing manufacturers into a corner were they are resorting to desperate measures over complicating engines with complex designs destined for massive (exspensice) failure
As for how bm can do it and vw can't absoluletly no idea that's a question for the lead engineer's

Or how a simple article in a newspaper not backed up by the actual regulated test details can wipe out 8% of a company value within minutes :-)Quote:

Pretty simple really.Quote:

But as well as that, with BMW being in a different market segment than VW, there will be a larger budget for to BMW to build an engine i.e. BMW engines will cost more per unit therefore there is the opportunity to assign cost to build in or develop the necessary technology to meet emmisions legislations whilst still improving performance. The price point of a VW engine may not have allowed for the technology to have been included hence why VAG opted for what they though may have been the more cost effective option for them.
But x 40 times the difference John? What exactly is significantly different VW v BMW? They both use direct injection, EGR, DPF, a Turbos, Calalytic Converters, NOx sensors, etc.
I don't buy it that BMW is 5 years ahead, they can't even get something as basic as a timing chain right, after years of glaring failures across multi-generational models (e6x/e9x and F1x/F3x).
On top of that BMW engines seem to have been consistently pushing out more power per litre (or cc) than the equivalent VW, yet if VW were to maintain the required level of emissions their cars would become undriveable due to the subsequent power loss in meeting required NOx levels.
Interesting too are the stories emerging on the back room agreements between Cameron & Merkel on deferring changes on emission requirements. The heat is coming on now!
