Complaint:
Noise:
A rattling noise may be heard from the area of the chain drive for approx. 2-5 seconds after engine start.
And/or:
Fault code entries in engine control unit:
SIM271DE20:
P001177 The position of the intake camshaft (cylinder bank 1) deviates from the specified value. The commanded position cannot be reached.
P001762 The position of the exhaust camshaft (cylinder bank 1) is implausible in comparison with the position of the
crankshaft. The signal comparison is faulty.
P001192 The position of the intake camshaft (cylinder bank 1) deviates from the specified value. The function or the
instruction is faulty.
P001195 The position of the intake camshaft (cylinder bank 1) deviates from the specified value. The mechanical setup is not OK.
P001477 The position of the exhaust camshaft (cylinder bank 1) deviates from the specified value. The commanded
position cannot be reached.
P001492 The position of the exhaust camshaft (cylinder bank 1) deviates from the specified value. The function or the
instruction is faulty.
P001495 The position of the exhaust camshaft (cylinder bank 1) deviates from the specified value. The mechanical
setup is not OK.
P001600 The position of the intake camshaft (cylinder bank 1) is implausible in comparison with the position of the
crankshaft.
P001662 The position of the intake camshaft (cylinder bank 1) is implausible in comparison with the position of the
crankshaft. The signal comparison is faulty.
P001700 The position of the exhaust camshaft (cylinder bank 1) is implausible in comparison with the position of the
crankshaft.
Cause:
The timing chain may have been stretched. This can be assessed by the following test step.
Remedy:
1. Remove chain tensioner (AR05.10-P-7800evo).
2. Mount measuring chain tensioner W 271 589 07 63 00 without seal and tighten to 20 Nm.
3. Turn the engine over 2x and determine the highest display value for the measuring chain tensioner throughout the
entire procedure.
4. Evaluate the value read off the scale of the measuring chain tensioner:

Measurement less than 79 mm: Perform work procedure A.
Measurement greater than 79 mm: Perform work procedure B.
Work procedure A:
1. Install new chain tensioner (AR05.10-P-7800evo).
Work procedure B:
1. Replace timing chain (AR05.10-P-7601*).
2. Visual inspection of intake/exhaust camshaft sprockets
3. Install new chain tensioner (AR05.10-P-7800evo).
