Fuel pump failure on my 75000 km run Tata Harrier: An expensive fix

And as expected, repair is not an option – typical for authorized service centers.

BHPian pkulkarni.2106 recently shared this with other enthusiasts:

So, I did get an appointment for servicing the car on 7th September.
But on 5th September, I started seeing diesel drops on the parking floor, accompanied by a strange “tick-tick-tick” sound whenever I tried to accelerate the car.

Sensing that something’s not right, I requested the TASS to pull in the appointment by one day. On 6th, when I was driving to the service center, the car started losing power. I pulled it aside immediately – the diesel was leaking like the water from a tap.

Called the flatbed & got the car towed to the authorized service center.

The inevitable happened – the SA told me that the high pressure injection pump (fuel pump) has failed. Specifically the bearing in the pump gave up. And as expected, repair is not an option – typical for authorized service centers. They say that a new pump costs around INR 70K. Along with it, the injectors and the fuel lines need cleaning too, which costs another 40K.
All in all, the total damage to the pocket is 1.5L including the routine service.

The car has done 75K KMs so far.

I just wanted to know if it’s normal the pump to give up so early?

Now It’s been 10 days and the car’s still sitting at the service center. They changed the FIP, timing belt (it was due anyways), high pressure rail and the other stuff as usual.

Since the FIP is a bit costly part, they called me to the workshop & installed it in my presence. The same day, they brought the fuel tank down for cleaning. As they opened the tank, it smelled like kerosene – the mechanic too acknowledged the smell. Along with that, it had the metallic dust, which, as per the SA, is from the crushed bearing of the FIP.

To be honest, I’ve never seen diesel in a bottle before – so, I don’t know what a good quality diesel looks like. But the one in the tank had a greenish tinge to it. Attaching the pics for reference. Can someone please confirm if this is how diesel should look like?

The injector cleaning/repair took the longest. They arrived yesterday & were fitted today. They did some “regeneration” today, but as per them, it kept failing. Now, the SA says that the pump in the tank doesn’t have enough pressure – hence the regen is failing & needs to be replaced. Needless to say, it’s going to take a few more days to arrive
