Vehicle sbs system. System at end of life according to code stored. Dealer advises that recall for my vehicle expired august 2015. Never received notice from mb. Costing me a fortune. Afraid to drive vehicle because of how sudden the system shuts down. Dealer tells me the system in the pump is breaking down.

The contact stated that the brakes had to be pumped in order to slow down and the emergency brake was engaged to stop the vehicle.
This vehicle is not making any noise or have any vibration during braking. But I notice that is braking more at front than the rear. *brake fluid is been changed by the dealer.
At this point, the fuel smell is so strong, the vehicle is almost undriveable. When in the garage, you can smell the fuel through the wall into the closet (the closest room beyond the garage).
The contact stated that fuel fumes were emitting from the rear of the vehicle and the check engine light illuminated. After inspecting the vehicle, the contact discovered a puddle of fuel under the back seat. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the issue.
Fuel smell in cabin extreme, fuel then leaks out near left rear wheel and pools where parked. Certainly a safety issue!
Decided to remove back seats to see if sending units were leaking in which I had heard about thru mb forums and wow there it was the rear passenger seat the side where the fuel goes in was soaked underneath and very damp on top of tank with fuel, on the driver's side it was the fuel smell not damp like the other side,…
