- Contact 1
- Contact 2
P0021
P0021
Diagnosis information - DME V8 DFI
Intake camshaft adjustment, bank 2
NOTE:
- A fault entry is made if the actual value deviates from the setpoint value by > 10 锟斤拷 camshaft angle or if adjustment takes place more slowly
than expected.
- An equalizing function for the camshaft of the other bank is already activated for small deviations.
- As a result of the equalizing function, a fault entry may be made for the other camshaft if this also deviates from the actual setpoint value by >
10 锟斤拷 camshaft angle.
Diagnostic conditions
- Perform a short test
or
- Vehicle voltage > 9 V
- Engine oil temperature -10 锟斤拷C ... 120 锟斤拷C (14 锟斤拷F ... 248 锟斤拷F)
- Engine speed 1,200 rpm ... 6,000 rpm
- No detection of fault P0010, P0020, P2088, P2089, P2092, P2093
Possible fault causes
- Solenoid hydraulic valve faulty
--> (e.g., mechanical fault or dirt in the oil circuit)
- Oil pressure too low
--> (e.g., due to oil dilution, oil thickening, wrong oil quality, fault in oil pressure control or oil pump)
- Intake camshaft adjuster faulty
- Camshaft stuck (incorrect or faulty installation)

P0030
Diagnosis information - DME V8 DFI
Driver for oxygen sensor heater ahead of catalytic converter, bank 1
NOTE: Do not use contact spray on the oxygen sensor plug connections, as this may cause irreparable damage to the wiring (blocking the reference
air channels).
NOTE: Do not confuse oxygen sensor ahead of catalytic converter and oxygen sensor behind catalytic converter as this will cause implausible fault
entries.
Diagnostic conditions
- Vehicle voltage > 9 V
- Engine running > 10 seconds
- Oxygen sensor heater ahead of catalytic converter active
Possible fault causes
- Short circuit to B+
- Short circuit to ground
- Open circuit in line
- Fuse FE 17 faulty (fuse carrier in plenum panel E-box)
- Loose contact in connector
- Oxygen sensor faulty
Affected contacts on the DME control unit connector
Connector [A]:
- Contact 33
Affected contacts on the oxygen sensor connector ahead of catalytic converter, bank 1:
