Servus bin neu hir im Motortalk Hab ein Problem mit meine Volvo V40 1.8 Bj2003 Abundzu jumps after 3 seconds first on no matter warm or cold the engine sometimes goes 3 days good is nothing last 2 weeks is once again well gone and time and again he does not want to start immediately. All 1-2 Wochn lights up the immobilizer light times. At the new start is again off. Have already let the Volvo dealer read out error memory error message: Communication to the control unit lost. The master said it can have the motor control unit or immobilizer control unit a make or have a cable from the motor control unit to the immobilizer control unit interrupting. The last 2 weeks was nox but the last few days he zicks against a bit. As soon as the car runs impeccable Have you ever had such a problem.
