330D thermostats -how many ?
Does the N57 2009 330D have a EGR stat as well as a main coolant stat ?
Looked through RealOEM and can only find a reference to a main stat.
Most of the forums discussions about slow warming up, low engine temp and poor mpg that Ive followed talk about replacing both main and EGR thermostats - but are these 2 stats on older 330D engines only?
