Mr. Hag and Unilevers have seen many who have had that warranty update done. MANY STILL HAD THE WRONG PLUNGERS OR ONLY A PARTIAL UPDATE IN THEM!. - NEVER TRUST IT!

I know to the outsider, we sound like a bunch of nay-sayers at times, but this one is as serious as it gets.

If the pump is failing, EVERY SINGLE MILE it is driven will chew up the engine exponentially, destroy everything. I have seen guys drive them for several days thinking it is not the problem, only to end up having to buy a new engine completely after it finally seizes up. It destroys much more than just the stuff you would replace if you were to inframe it and becomes a lot less expensive to replace the entire engine. It messes up the crank, cam, bearings, rockers, geartrain, geartrain bearings, oil pump, oil cooler, oil thermostat, bypass valve, turbo, air compressor, sometimes even the power steering pump. Basically everything that has oil running through or passing over it.


If I owned one of those engines and had that code, I would have pulled off the oil filter and cut it open if need be before driving it another mile. If even a hint of shavings found, I would have it towed somewhere instead of cranking it up again. - Yes, it is that bad.

You never know, Maybe it is something simple like a failing fuel filter or flow/supply problem. Perhaps air in the system or even a very leaky injector or pressure relief valve from trash getting into the fuel when the filter was changed. Hopefully it IS something of lesser importance and thats all it is. Maybe you won the lottery and it is not the pump, but not shutting the engine down immediately and having it investigated/resolved at the first signs of that particular issue is taking a huge gamble -- HUGE!.

How many miles are on the engine?
