A one time error code will be stored in the car's computer memory until it is read and reset by a mechanic's diagnostics equipment. if the vehicle seems to be running fine, you can reset the computer by disconnecting the battery's negative cable for a few seconds. If the error is reoccuring then the light will just come back on again. If this is the case you need to have the car's computer hooked up to a diagnostics equipment to read the error code which should tell you where the problem is. Error codes sent to the comp. are what causes these lights to come on and are hard to diagnose without the equipment so you'll probably need a mechanic. Wish I could help more.

Could be a fuse problem. check to make sure the main fuse (which is usually undo the hood and would be an 60,80 or 100 amp) isn't blown. If it isn't you may just have to have the lights cleared from a scanner. The computer may have detected the reverse polarity and thought it was a problem in all the systems. try this first, but please keep me informed. Thanks

You have the polarity of the battery backward somewhere. Did you replace the starter and hook it up backwards. Difficult but possible. Check your positive and negative on the battery itself.

Battery went dead had to jump start, now cd player wont work on 2006 mercedes

It should be in the manual supplied with the car. If not call mercedes and give them your vin, reg private detail etc and if you get a nice person,problem will be solved. It happen to me, but not a merc that you gladly own. I'm n battery not sure about this advice but a merc uses a high voltage and you may need a new battery.

How to reset abs light on 1992 300e mercedes. My car was parked on the street. One day when I started it

In all of the other forums the mechanics talk about replacing or checking the fuses on the OVP which is the Over Voltage Protection Relay located on the right side of the engine compartment behind the battery. That might be a good place to start checking.

hello i;m an m.b. tech. and if that is all that happened your really lucky. on the straight six e class there is an over voltage rely that powers up the a.b.s. module as well as the c.i.s. and idle speed modules. usually if that relay is defective the idle is high and the a.b.s. light is on. the relay is located behind the battery in the engine compartment. there is a plastic cover that just pulls out behind the battery and it is a silver rely with a red lid and a 10 amp fuse. most likely the 10 amp fuse is blown. try replacing the fuse and see if the light goes out. if not replace the overvoltage relay.
