Electric EGR operation too? Not sure I've seen that on the e53 - only the later e70 and some earlier sedans using the M57TU/TU2. |
Well actually not that much different.
The very same vacuum operated EGR valve. (Of course the housing is a bit different because the throttle valve is connected to EGR valve.) AFAIK E70 3.5d (US variant) is the only M57 engine with electric EGR valve. The EGR system on this is much more complex with separate low and high pressure EGR.
