Scheme 177

1. Start the engine
2. Read off the value for the camshaft closing angle and the desired value for the camshaft closing angle
3. Active the quick test of camshaft control by clicking the start button
4. Increase the engine speed (RPM) to approximately 2500 RPM and keep the engine running at this speed. When the engine speed (RPM) increases, the control module will start the quick test to guide the camshaft to the different target values. During the quick test, check that the closing angle of the camshaft (actual value) corresponds to the desired camshaft closing angle (target value) to an accuracy of ±10°. If the values do not correspond to an accuracy of ±10°, the function is faulty. Deviation between the values can be read off in the lower display. Carry out the check for approximately 15 seconds at an engine speed (RPM) of 2500 RPM. When the desired value is stable once again, the test has been completed. To restart the test, let the engine return to idle speed, then increase the engine speed to approximately 2500 RPM again. The fault is intermittent if the function is OK. NOTE: The test is active until the ignition is switched off. Switch off the ignition before the vehicle is delivered to the customer.

1. Continue Refer to «CHECKING COMPONENTS»(ref-466669-S01404158672012042500000)

CHECKING COMPONENTS

Check the engine oil level and quality. Check for contaminants in particular.

Check the engine oil pressure.

Remove the camshaft reset valve. Check the oil ducts for the cylinder head for the camshaft reset valve (intake) for blockages and dirt.

For variable valve timing control to operate correctly the engine oil must be at the correct level, of the correct quality and not contaminated.

Check the engine oil level and quality. Check for contaminants in particular.

The normal value for adaption is 27°CA (+/-8°CA). If the value is too high when the engine is at operating temperature, the cause of the fault is probably one of the following

1. Camshaft belt incorrectly seated
2. Incorrect basic setting for the timing belt
3. Faulty camshaft reset valve (the slide in the valve has stuck).

HINT: First try adjusting the basic setting of the camshaft. Test drive the car. Then read off the camshaft discrepancy at idle speed with the engine at operating temperature. The value must be between -8° and +8°. If the value is incorrect when the basic setting of the camshaft is correct, try cleaning the camshaft reset valve.

Note. The camshafts must be adjusted using the adjustment tool for the camshafts and crankshaft in the prescribed manner.

CHECKING BATTERY VOLTAGE

1. Start the engine
2. Read off the battery voltage and the target value of the generator (GEN) charge voltage
3. Load the battery by switching on high current consumers such as high beam and the blower fan etc. Check that the battery voltage is approximately 13.5 -14.9 V. Check that the battery voltage is approximately the same as the target value for the generator (GEN) voltage. Try different engine speeds (RPM). The fault is permanent if the function is incorrect. If the voltage is correct, this is an indication that the fault was present previously but is not active at the moment, i. e. an intermittent fault. HINT: This diagnostic trouble code can be stored if a battery charger with too high charge voltage has been connected.
