1. Take the valve (it is necessary to use a key 8.0117 AE for electrically the operated Bosch valves). |
2. Measure the electromagnet resistance (about 8 Ohms). If the measured value of resistance does not correspond to the above, it is necessary to replace the valve. |
3. Install the valve supplied with a new round sealing ring and tighten the moment of 15 Roto Diesel or 20 Bosch. |
