Acceleration problem with the V50

Hello dear Motor-Talk municipality I have been driving my V50 2.0D since June 2006 and was so far satisfied about everything. I have been driving 37500 km on it so far and it was never a problem. Last week suddenly I step on the accelerator and it does not accelerate as it usually takes off – on the contrary more than 2000 tours were not in any gear any more. Unfortunately the car did not run in the 6 course any more like 80 kmh. One day later I went to the dealer and there was of course nothing more, everything was like always ( funny thing ) The master was able to find out but nothing – but the control unit was in suspicion. So read out and see since the control unit has hung up or crashed briefly. Since he has started a new software which I unfortunately God also have to pay because no guarantee exists anymore but as long as my elch again clean is worth to me? After that someone kept shopping again sounds wonderful. Until today morning, there went off again, stopped and then switched on the engine – then it was gone (so the MEISTER told me that it was really bad and then?
