ASR problem limp mode etc opinion needed.

[just5]

I know very little about cars as I just drive them and I am stuck with a big problem. I have an S600 V12 1991. I had my battery replaced along with the battery charger (cant remember what it is called) because the battery would not charge. For the first hour or so after i got my car back I believe that ASR light was on but everything was fine and it disappeared after a while. It has been around 4 weeks now and today while driving in traffic suddenly ASR goes on and the car goes into Limp Home mode. I turned off the car and turned it back on and it was fine again. Few hours later it did exactly the same thing but this time I had to wait longer for it to turn back on.

I read all of the other posts and forums and I know that many go to their mechanic to get the error codes and some have to pay lots of money to get it fixed. I dont have money to get it fixed and I am actually in Switzerland right now and just have 2 weeks left here before I have to drive back to Germany where I live (It is 600KM which is a few hundred miles!). My question is, is it safe for me to drive back to Germany? Will I be able to make it? Should I stop driving for 2 weeks and take the bus, and then drive to Germany? I really dont have the money to get it fixed here in Switzerland so any help would be appreciated!!!
