The first code does not show on the list. Also there are two engines possible so I have included the diagram for both.

2007 BMW 640 codes P1727, P0335, P0597, P0021

code P1727 – No information listed there is a P1721. Check to see if you have the wrong code number (is “7” really a 1 ?).


DTC P0335: Crankshaft Position Sensor 'A' Circuit (SIG)
BMW Fault Code (hex) 0x2B5C
BMW Fault Code (dez) 11100
BMW Fault Code Description VS-Text = Crankshaft sensor, signal

Component
Crankshaft Position Sensor
Subcomponent
Electrical

Monitoring criteria
Engine turning over
Fault debouncing

18 camshaft or crankshaft flanks
Terminal conditions - Terminal 15=TRUE
Voltage conditions - none
Temperature conditions - none
Time conditions - none
System test - None
Signal information - Target: 58 teeth for each crankshaft revolution
Calculated value Y/N - NO

Possible Fault Causes
DME detects camshaft teeth but no crankshaft teeth: Short to ground or battery voltage, wire off. Crankshaft sensor failure. Signal fault (spikes, etc.) or intermittent contact in one camshaft sensor wire.

Repair procedures (plant/service)
Check plug / wiring harness, check geometry of sensor and reluctor, replace sensor as indicated

MIL illumination/CC message/emergency program
MIL on in 2nd driving cycle VVT emergency default mode (max. stroke) active VANOS emergency default mode (spec. 120°) active RPM sensor emergency default mode active
Remarks
VANOS intake and exhaust sides remain at travel limits (120° offset). Revisions to application still pending for E70.


DTC P0597: Thermostat Heater Control Circuit/Open (SIG)
BMW Fault Code (hex) = 0x2EF5
BMW Fault Code (dez) = 12021
BMW Fault Code Description VS-Text = Map thermostat, activation
Component = Thermostat
Subcomponent = Electrical

Monitoring criteria
Current at Pin 3--12 I > 1.1 A
Fault debouncing = n> 40 rpm
Terminal conditions = Terminal 15=TRUE
Voltage conditions = 9.5 V < U < 17.9 V
Temperature conditions = none
Time conditions = after 800 ms
System test = control kfk
Signal information = Low Side control signal
Calculated value Y/N = N
Possible Fault Causes Program map thermostat, open wire

Repair procedures (plant/service)
Check/replace components and wiring

MIL illumination/CC message/emergency program
MIL on in 2nd DC, US version only

Remarks
None


DTC P0021: 'A' Camshaft Position - Timing Over-Advanced or System Performance (Bank 2) (MIN)

BMW Fault Code (hex) = 0x2A8B
BMW Fault Code (dez) = 10891
BMW Fault Code Description VS-Text = Inlet VANOS, adaptation stop 2

Component = Camshaft Position Timing
Subcomponent = Intake

Monitoring criteria
Bank 2 intake travel-limit adaptation monitor (if OK: 115°KW < Vsa2_adp < 141°KW) VANOS must be at travel limit, i.e., Vsa2_sprs=120°KW.

Fault debouncing = Entered immediately
Terminal conditions = KL_15 = true
Voltage conditions = none
Temperature conditions = - 10.5 °C< tmot < 114.8 °C
Time conditions = Intake VANOS at travel limits > 5 sec. (K_VNS_ADEND)

System test = none
Signal information = none
Calculated value Y/N = Yes

Possible Fault Causes
Seized solenoid valve (contamination or mechanical defect). Binding or seizure in VANOS adjustment mechanism. Contamination. Chain length. Reluctor shifted on camshaft. Can be collateral fault from camshaft sensor fault if camshaft sensor fault and VANOS fault are logged simultaneously.

Repair procedures (plant/service)
Test sequence (check to determine whether fault is still present after each step):
1.If corresponding camshaft sensor fault has been logged, start by checking camshaft sensor
2.Check VANOS valve for contamination
3.Check reluctor position
4.Check chain length and tension

MIL illumination/CC message/emergency program
US: Standard OBD fault; MIL on after 2 driving cycles, transmits to scan tool; no EPCL; delete fault after 40 warm-up cycles ECE: AS US but no MIL

Remarks
None


Crank Position Sensor location:
Crankshaft Position Sensor (4.8L) (B6203) Right side of engine.

Crankshaft Position Sensor (5.0L) (B6203) Under left center of vehicle.

Also this forum is for the Fxx generation 6-series. Yours is an Exx generation. Try searching the E60 5-series forum. Information on the 550i should be of help too.
