2012 Passat TDI

Does anyone know if the TDI motor in the upcoming 2012 Passat is significantly different then those in the 2011 Golf or if there is another HPFP revision since the last one in November? Thanks.

I am not an expert nor do I claim to be, but I believe the engines are significantly different. I say this because the Passat uses the urea based exhaust treatment wheras the Golf does not. I know this is mostly an exhaust treatment, but it is pretty big and leads me to believe that they are fairly different in architecture. Anyone with more experience/info care to chime in?

According to what they are saying at the autoshows, same engine just slightly different emmissions treatment.
