Very sad to know about this fuel pump issue you faced but happy that MASC diagnosed it correctly and replaced the pump under warranty. Crossing a hump @ 40 kmph should not disturb the fuel pump. Since this is the first instance of a fuel pump failure reported for a TUV (and that too due to the car taking a shock of crossing a hump), I won't go to the extent of calling it a reliability issue, but yes I agree that M&M should have provided a more robust design. This can be a common phenomenon on our roads. Given the fact that M&M vehicles are abuse friendly and mostly preferred for rough road usage, M&M and the fuel pump manufacturer should seriously reconsider the pump design. Quote:

Did you get any indication of what caused the failure? Could it be due to poor fuel quality? I've heard that particles in the fuel or water could lead to this. |
I agree about your comment, but here the issue is not caused due to bad fuel quality but the sudden shock of crossing the hump at more than desired speed, which seems to have unsettled the pump. Quote:

I agree, pictures help a lot. Quote:

So true, parts replaced under warranty are never given to the customer. They are returned to the OEM for further analysis and finding the root cause of failure. I am sure Ntomer's pump must have been dispatched to the pump manufacturer. Quote:

I think it's a one-off case (feel free to correct me) and you are just damn unlucky. |
Both of you are probably right. The 3 cylinder engines probably use the Low Cost Common Rail (LCCR) System from M/s. BOSCH. Refer page# 17 in the attached document on "Case study on developing 3 cylinder 1.5 Liter cost efficient diesel engine" MahindraNewMUV3Cyl.pdf Quote:

I know this is OT as it is another car altogether but since you mentioned the bump yourself I thought would write about my experience. |
Thank you diyguy for sharing your experience. Your case seems to be more or less similar to what Ntomer has experienced. The common rail and new generation fuel pumps seem to be more complicated by nature of their design. They have now become more susceptible to damages from bad fuel quality or unwanted shocks. In your case too was the pump replaced under warranty? |
