All facelift 3.0d models (M57N engine) with DPF (EU4) have intake manifold swirl flaps. There are M57N EU3 models without DPF and those don't have swirl flaps. |
Thank you! So if I got it correctly:
Vacuum solenoid 1 - #11747796634 - (vacuum hose with
blue stripe), located on the intake manifold controls EGR.
Vacuum solenoid 2 - #11747810831 - (vacuum hose with the
yellow stripe) is located on the intake manifold and controls swirl flaps.
Vacuum solenoid 3 - #11747810831 - (vacuum hose with the
red stripe) is located
somewhere else (?), and is used to control engine mounts, which are again, hydraulic-controlled.
Or something like that
Thanks again!
I'll let you guys know if I finally managed to get rid of 4501 fault code. Maybe I'll also clean EGR in the process. But that's a discussion for another topic.
