Locating Over Voltage Protection (OVP) Relay on '94 S280

[whisperingrob]

I had to jump start my 1994 S280 at the weekend after leaving lights on all day. The ABS light is now permanently lit after starting and I have read that the fuse could have blown on the Over Voltage Protection Relay. Can anyone tell me where this is located?
Many thanks.

If its anything like a W124 it will be found up behind the battery(you have to remove it) and behind the black plastic cover that protects the ECU. The OVP on mine was to the right and is about 3 inches high and has a fuse on the top of it.

On my C280 it was located just in front of the battery.

Rather than just changing the fuse I would replace the complete relay, about £60. The originals had a design fault and will fail at some stage...new ones have a re-design.
