98' E320 OverVoltageRelay - ???
My check engine light came on, so I disconnected the battery cable. Now the check engine light is off, but the ABS and BAS/ASR
come on. I figure it got to be the OVR. I looked almost everywhere and couldn't find it. Does anyone know where it is? or am I looking at the right direction to reset the ABS and BAS/ASR lights?

Your 98 E320 doesn't have the Overvolt Relay Problem. But the indication that your BAS/ASR and ABS lights are on make me think that you have a voltage problem. And you were messing with the battery, but the cables are on properly now?! I am not sure... but be sure and check all of the fuses, even replace the fuses for ASR/BAS & ABS because there could be (doubtful on late model though..) a hairline crack.

But you can check your voltage via your climate control! But damn, it's been awhile.... not sure I remember exactly how on a 98 W210. Here's a try:

1. Start Engine.
2. Set climate control to 72 (both sides) and press AUTO.
3. Then press and hold REST (for roughly 5 seconds) until a different menu appears. One side of the display will read the menu number (1-50 or so, inconsistent though).
4. Press Auto (left or right; respectively, up or down), until you get to the voltage meter. But I can't recall which number the voltage is? If you do fine a menu that appears to have 12.9 to 13.1 or so (or near that), then you have probably found it. I'm sorry I don't remember.

But I printed out the codes for a friend of mine who has a 99 E430, it should be the same. I will get the VOLTAGE number tomorrow for you though. But atleast this is a start (I think the voltage reading is something like 20 or 24 or something?)

Good luck and if you have any questions, please ask! :)

((My point is, this way we can try and see if you're having a voltage problem, those indicator lights make me think that those systems aren't getting enough voltage!))
