◆ Always renew spring-type hose clips with screw-type hose clips.
-
◆ For trouble-free operation of the electrical components a voltage of at least 11.5 V is necessary.
-
◆ If the engine starts, runs for a short period and then stops, after fault finding, repairs or component tests, then the fault may lie with the immobilizer which is blocking the engine control unit. The fault memory must be interrogated and if necessary the control unit matched => Page 24-87

-
◆ During some checks it can happen that the control unit will recognise and store a fault. Therefore after completing all checks and repairs the fault memory must be interrogated and if necessary erased.
