I've got a 2010 tdi Roomster. 

The other day the fuse for the 12v sockets blew and I replaced the fuse. 

While trying to locate the fuse I put one back in the wrong place, resulting in the car turning over but not starting. 

This was easily sorted, the car is running fine but the glow plug light is now blinking. 

Is there a way to reset this? 

Thanks

I did pretty much the same thing. I blew the horn fuse.

 

Now, first, check all your taillights are working. If not, then it's most likely the brake light switch. If it's one or two, then replace the offending bulb/s.

 

If it's none of those things (like me), then yes, you need to have it reset via the OBD port.
