EXCERPT:

After the cooling system has been filled with the vacuum filling unit, another bleeding procedure must be performed for vehicles with an electric coolant pump

NOTE: Do not open the coolant expansion tank cap during the bleeding procedure. Switch on the low-beam headlights to perform the bleeding procedure. If the low-beam headlights are not switched on, the ignition (Terminal 15) will switch off automatically after a certain period of time and interrupt the bleeding
procedure.

1. Connect battery charger.
2. Switch the ignition on.
3. Switch on low-beam headlight.
4. Set heating to maximum temperature. Take back blower to smallest stage.
5. FES (driving experience switch) must not be in ECO PRO!
6. Press accelerator pedal for 10 seconds to floor. Engine must not be started.
7. The venting procedure is started when the accelerator pedal is pressed and takes approx. 12 minutes.
(Electric coolant pump was activated and shuts down automatically after approx. 12 min).
8. Then adjust fluid level in the coolant expansion tank to maximum.
9. Check cooling system for leaks.
10. If the ventilation has to be performed again, deactivate DME completely (remove ignition key for approx.
3 minutes). Then repeat from point 3.
Check function of cooling system.
Check cooling system for tightness.

EXCERPT:

Engine – SI Techniques – N52 6-Cylinder
N52 ENGINE, VALVETRONIC: E60, E61, E63, E64, E65, E66, E87, E90, E91
The Valvetronic consists of fully variable control of the valve lift combined with the variable camshaft control
unit (VANOS).
As of the N52 engine, the 6-cylinder petrol engine is equipped with Valvetronic. The advantages this technology are:

Enhancement of engine dynamics

Improvement in the emission values
DESIGN
Fig. 1: Identifying Variable Camshaft Control Unit Components
The fully variable valve timing
Fig. 2: Identifying Setting For Minimum And Maximum Valve Lift
The fully variable valve lift timing is implemented with the following components:

Electric servomotor

Eccentric shaft

Intermediate lever

Return spring

Roller cam follower
The actuator motor is fitted above the camshafts in the cylinder head. The actuator motor adjusts the eccentric shaft. The worm shaft of the electric motor engages in the work gear attached to the eccentric shaft. After adjustment, the eccentric shaft does not have to be locked in any special way, as the worm gear has an adequate self-regulation system. The eccentric shaft adjusts the valve lift on the inlet side. The intermediate lever changes the transmission coefficient between the camshaft and roller cam follower. In the full load position, the valve lift and opening duration are at the maximum. In the idle position, the valve lift and opening duration are at the minimum. The roller cam followers and associated intermediate levers are split into 4 groups. To this end, an ID code is stamped in the components. Each pair always has the same class. The assignment of the roller cam followers and intermediate levers ensures that the cylinders are evenly filled, even with minimum lift.
ADVANCE
In the lower range of motion of the valves, the possibility for harmonization by means of so-called advance is supported.
The inlet valves of a cylinder are opened synchronously up to a lift of 0.2 mm. As of this lift, valve 1 begins to advance. Valve 2 opens with a slight delay a little later. Valve 2 catches up with valve 1 with a stroke of approx. 6 mm. From then on, they open synchronously. These response characteristics favor the gas mixture flowing into the cylinders. The cross section of the inlet valve openings has been kept small to achieve a significantly higher flow rate with the intake volume remaining the same. This flow rate is used for better mixing of the
intake mixture.
