This could be caused by a faulty Crank position sensor. The computers are expensive for this and not something that commonly fails on these. Have the fuel pumpchecked for operation and pressure. Check for spark at the plugs. Then we can procede further if you would like.

SOURCE: my mercedes benz 400 sel airconditioner is only

You are out of freon or have a leak that caused you to run out.If your a/c system has never been fully changed over,it has to be done by a dealer,new freon or fix leak that is.Pre-1995 cars have the R-12 freon system and shops have to have a special license just to buy,sell,use,dispose of R-12.1995 and after have R-134a freon in them.The 2 systems are not compatible with each other at all.I have heard the R-12 is real expensive now but I do not know how much.Call a couple of shops and tell them your situation and see what they say or recommend.I would call AAA approved shops because they have better standards just to have that approval and give 10% discount on labor if you have AAA.
Good luck! Greg

We have a 1993 Mercedes 400 SEL. The climate control unit has a problem where it will keep turning on and killing the battery.We have been disconnecting the battery cables every time we shut down for more...


The ASR and ABS are voltage sensitive, so each time you disconnect them from power, they will reset. To cancel the ASR light, start engine then turn steering wheel full lock to right, then lock to left...ASR should extinguish. ABS light should then go out once you drive above 8 mph for 100yards or so. Until you can have the climate control looked at by a professional, I would locate and remove the fuse for it when you park up. Much better than disconnecting battery.

I gave a jump to my 1993 400 sel now the abs and asr dash lights will not go out and the speed ometer does not work


Check fuses, you are not supposed to "jump" MB thats why they have forever roadside assistance. You charge battery while disconnected and reconnect to start.
