Read MVB 023 (required -100 ....+100). High negative values - smaller or greater than -60...+60 (e.g. -75) - indicate a fuel supply problem. Check the complete fuel supply according to the workshop manual. A value over +60 suggests a jammed pump injector element or poor fuel quality. Replace only the pump injector element which is too high in the measured value block. All other pump injector elements whose measured value blocks are within the required range must not be replaced.

Read the measured value blocks (MV 001, 004, 007, 013, 018 and 023 of the engine control unit at idle speed and MVB 023 additionally at 2,000 rpm and at cut-off speed (engine operating temperature) and make the following assessment: •Check the injected fuel quantity in the MVB 001 display 2 (required: 3.0 mg/H ...9.0 mg/H, air conditioning switched off).•In MVB 004 display 4 the synchronisation angle is checked (required -3...+3 &#176, the value must not be fluctuate more than 0.5 (toothed belt tension).•Read the temperatures in the MVB 007 with cooled-down engine and at outside temperature for plausibility. During the warm-up phase the temperatures should rise plausibly. •Read MVB 013 idle speed rest control. The values are between -3.01 mg/H ...+3.01 mg/H. If the maximum values are almost reached in both directions (positive or negative), poor combustion can be assumed. This may be caused by the engine mechanics (compression) as well as the fuel supply and the pump injector elements. If the checks are not successful, replace the pump injector element with the high value (positive or negative) for the idle speed rest control. The idle speed rest control must always have some fluctuation. If the 4 displayed values are static, the engine speed is too high or the injected fuel quantity in the MVB 1 is smaller than 3 mg/H.
Possible causes: Air mass values not all right or the pump injector elements are rich.
