The measurements for the EGE test begin with engine conditioning. Before starting the EGE test, check idle and cut-off speeds and adjust if necessary. This can render an additional test superfluous.
- Perform a test drive if possible. During the test drive, accelerate to cut-off speed in 2nd gear and check for pump cut-off.
- Run engine at approx. 3000 rpm to operating temperature (oil temperature >= 80 °C). We do not recommend running the engine to operating temperature with the vehicle stationary at idle speed as this results in increased soot deposits in the exhaust system.
- The oil temperature should be measured when the engine is at a standstill in order to prevent damage to the engine. Use the oil temperature tester MKM-596-A to check the oil temperature. If there are access problems, read the temperature off the coolant temperature display.
- Connect testers according to manufacturer's instructions.
- In vehicles with automatic transmission, engage gear lever in "P" position.
- Check idle speed with TECH 2 and adjust if necessary.
- Activate power steering, AT and AC and check whether engine runs correctly at idle speed.
- Run the engine for at least 60 s at approx. 3000 rpm in order to ensure that the catalytic converter has reached operating temperature.
There should only be a very short time period between testing and engine warm-up, otherwise the oil temperature will not correspond to the catalytic converter temperature.
Recommendation: Before the EGE test, accelerate the engine at operating temperature to cut-off speed at least 5 – 8 times, in order to reduce the soot component in the exhaust system (blow through).
Run engine to operating temperature on test rig / by means of quick driving (motorway). The engine and exhaust system are "blown through", whereby a smaller proportion of soot resulting from deposits in the exhaust emissions is to be noted.
Begin the EGE test immediately after warm-up in order to achieve an optimal result under the best possible conditions.
Note. The alternator belt tension must be correct.

In the event that the adaptation or calibration fails to produce a stable indicated engine speed, the alternator must be loaded by: Switching on lights and, if necessary, heated rear screen and additional headlamps (but not those with gas discharge lamps). Switching on electric motors (heater fan) and those with regulator circuit (AC) must be avoided, as these can affect the stability of the engine speed display. The adaptation or calibration must then be repeated.
Compiling the Test Report (Diesel Engines)
Errors can be eliminated using the diagnostic equipment. As a result, parts are then only replaced if it is certain that the signal emitted does not correspond with the nominal value or if the incoming signal cannot be converted. To successfully find and eliminate faults on electronic components, it is essential to have an understanding of the system and to possess the appropriate diagnostic equipment.
Note. Check voltage supply and ground connection
The person responsible for the test must issue a test certificate after the exhaust gas emissions test. The test certificate must contain the following information:
- date, time, testing location, testing device type, EGE software version
- VIN
- Vehicle nominal data, vehicle actual data
- result of visual check on components and engine diagnostic system control lamp - not satisfactory (not OK), - satisfactory (OK)
- Result of the smoke density measurement
- Overall result: - EGE test passed; disc awarded as per appendix IXa - EGE test failed
- Month, year when next exhaust gas emissions test due, signature of the person responsible for the test and, in the case of vehicle workshops approved in accordance with § 47b StVZO, the inspection number.
