Your BAS/ESP light could be multiple problems. Most are not a problem, just a warning. Check your Owners Manual on that Symbol.
If your ESP came on, you wheels might have spinned, on a sharp turn, on an oily road, snowy road, wet road etc. and the ESP will quickly flash and then go away.
BAS light might come on for a simple Brake Pad change. Or your BAS sensor detected an early sign of brake pad wear.
Sometimes MB lights come on and boy they sure do get your attention!
The occasional flash is not a problem, it's the one's that stay on that is a problem.
Get to Autozone, similar store and pull the Codes and that will tell you a lot.
Check your Key FOB and make sure you have fresh new batteries in there.
Remember when you switch out your battery all your memory will die and a dead FOB will not allow you back in your MB. DO NOT FORGET YOUR CAR RADIO CODE. Write it down! It will lock you out if you lose all power.
Get the Battery tested. Don't buy one until you test it. Walmart also sells those batteries, Pep Boys, Autozone etc.
Test, Test, Test before you spend, spend, spend.

I left it because I was a bit worried so was going to wait to the weekend and try and get information to what i might be.
After reading forums about what it could be I went back to my car this morning to see if turning the wheel to ether side would work.
But on approaching my car I couldn't get the remote key to open it, so I manually unlocked it. When then attempting to turn the car on it, it wouldn't start. No noise nothing it was as if the battery had drained or died.
I plan to buy a new battery etc but could you help me and tell me if this pointless because this means something else is wrong not the battery. I read something about seat modules but know nothing abou cars so dont even know what they are.
Please please please help. My car is a A Class if that helps xx
