thank you for the replies and for putting it in fairly plain terms. im going to go today to see if i can get the codes checked. ive read that in many cases its a progressive problem so I thought that if I dont drive the car for 2 weeks it wont get any worse and Ill manage to get to germany but because it happened twice on the first day then Im not sure anymore.

just throwing this fact out; my old battery was 100ah V12 while the one that they put in couple weeks ago is 90ah v12 from what I remember. I believe that these are the figures. Does this have any effect on it? Im not sure if this is related at all but sometimes as I start up the car and simply put on D, the car kind of chokes a bit fr a few seconds while driving min speed. It doesnt choke on start up but as you put on D and start moving the first 10-20 meters. Could both of these symptoms are related to the ASR and low voltage?
