The vehicle pull back effect is not due to the fuel pump but ECU? After the fuel pump changed, did you encounter the same symptom?
Seems life they still have a very long way to go to improve the quality of service.
About 6 months, I had pull back only when the fuel is very low which was understandable. Once the car stopped on gentle hill near Pantai Hospital and could only go in reverse. The car didn't move forward even after putting petro of few liters. The car just fall in reverse when the gear was engaged to "D". But in reverse, you can control the car. At the same time all the error messages appeared. That's when they changed the HPFP
The car was ok for a couple of days then started having pull back even there was petrol. In September, they told it may be due to the latest HPFP they fixed may not be compatible with the computer system. Not sure how far it is correct but a quick check with the Mercedes mechanical school said it may be possible.
The annoying part was when I complained in September, my Petrol was in half tank. I asked them to drain the petrol and test it out but they refused and asked me to bring back when the petrol is low. When I did last week, the car stopped once but managed to restart but pulling all they endangering me!
They never did call me since last Saturday. When I called them on Thursday, they said it is due to the ECU and waiting for approval and most likely I can get the car on Saturday. Until today no call back.
So, I need to start my complain writing to the TOP continuously like how I did when I got car! :-(
