E320 SBC Pump failure
Last Wednesday I'd just gotten off the highway when a red brake warning light came on indicating the car should be stopped immediately. I was approaching an intersection full of cars and the brake pedal went all the way to the floor when I pressed on the brakes, but I wasn't slowing down at all. I shifted into Neutral and started looking for a soft landing spot. Luckily the light turned green and as I coasted into the intersection I turned the car onto a less busy street and pressed the emergency brake which brought me to a safe stop. That was sheer luck! The car was towed to my independent garage who told me the brakes were functioning properly but Mercedes needed to diagnose the problem. I bought my 2003 E320 used and hadn't had it serviced by a dealer so I wasn't sure what would happen...Although the repair was covered at the dealership under an MB warranty the Service Mgr. told me the SBC pump had not been recalled, it is simply referred to as a "campaign". He further assured me MB does not consider this a safety problem because I could stop the car with the brake pedal if I had the strength of "King Kong". Well, I don't! I was lucky, and am appalled that MB would treat this like it's a normal occurrence.
I had noticed in recent days the humming of the SBC pump was longer than usual but the Service Mgr. didn't think this was an indication of the pending doom. My head is still spinning.
