Hi Ryan:

I'm not familiar with Mercedes products, but I am very familiar with Volkswagen products, and they use a very similar system for ASR, ABS, and ESP.

My suggestion is that you just ignore the problem until you get to some location (perhaps a big Moroccan city in the north, or perhaps even back to Europe) where you are comfortable and confident that you can get the problem fixed.

There is nothing mechanically "wrong" with your vehicle. As you have determined through your own investigations - and it sounds like you know what you are doing, and what you are dealing with - you have suffered a loss of functionality of the above-mentioned safety systems. That's all.

Before I retired, I was an aircraft pilot and aircraft maintenance technician. All large aircraft have what is known as a "Minimum Equipment List' (MEL). When a component or system fails on an aircraft, it doesn't automatically ground the aircraft. The pilot looks up the failed system on the MEL, and the MEL provides guidance about whether or not the aircraft can continue to be safely used with the inoperative component or system.

If your Sprinter was an aircraft, I suspect the MEL guidance for your particular system failure would look like this:

"Vehicle can continue to be operated until reaching a service facility, but anti-lock braking, stability control, and wheelslip regulation will not be available. Avoid operation on sandy or slippery surfaces, and be aware that one or more wheels may lock up if hard braking force is applied."

In other words, take note of your failure, don't go down roads that you wouldn't travel on with an ordinary passenger car, and be aware that you no longer have ABS protection. But otherwise, continue your journey as normal.
