You can either take it to a mechanic who has a MB computer diagnostic system or if you're a DIYer, you can build Arthur Dalton's code reader and post the codes. The list members will help you when we know the codes.
Been there, done the DIY with the help of the forum members.
PS Take care of it now, because it will keep recurring.

Actually, ASR stands for "acceleration slip control." So says the 1992 MB factory shop overview of the 400e/500e. I guess MB is not one for accurate acronyms
Not that any of this matters....just an interesting observation
as for your issue, ASR is essentially the nervous system of a 124. ASR lights/limp/other components are all interconnected, so yes, you've got to read the codes and go for the cheapest potential culprits first
