Wow it seems like theres not one website worldwide that can list where the ABS pump relay is located in my 2005 W164 ML500. But not just where the fuse boxes are but which friggn relay it actually is. Whats the big weirdass secret ? "oh, i know but... People its not as top secret as Mercedes make it out to be. They must be the tightest car manufacturing company anywhere. Why dont they list all the fuses and relays in the owner manuals ? So they can rip the crap out of the very people that keep them in jobs? Not even on the insides of the fuse box lids, wtf, stupid approach to keeping their return buyers with them. So who wants to spill the beans of this topsecret location ? Haha...

Why not continue in your original thread? It is still not clear what is it that you are driving.

Witek_M. Thanks for replying. It is written in the headline for my post, But its a 2005 W164 ML500. I think i have found the answer but have not yet been to have a look. Someone said that the ABS relay is inside the plastic cover of the ABS pump itself, would you agree ? Cheers.

What is your VIN? What is the problem? What are the symptoms?

The VIN is WDC1641752A064856 . The symptons were , Two days ago I heard a pump sounding noise after I switched off the car and it went for a while, long enough that it flattened my battery. The noise was coming from under the hood at the front left, so im hoping its only the ABS relay.

In that system there are no external relays. ABS pump is driven directly by ESP control module. Sure there is relay inside but it is not user replaceable.

To clarify what your vehicle is. It is 2006 ML500 4Matic.

Here is data card. Code 806 is model year.
