In engineering, and specifically in document control, we often refer to the revision and version of a design. Those words may sound the same, but frequently they're set apart by the form-fit-function standard.

Changes which impact form, fit or function are revision changes, whereas small updates that don't substantially change a given design are version changes.

Put another way, you can mix inventory of parts of varying version, usually. One would never mix inventory of differing revisions.

Based on this part number curiosity, it would seem that this isn't deemed a major change. It could be that the problem has a low incidence rate overall -- or at least, a low estimated incidence rate. And so, the "bad" parts are still actually useable and good, and can be used to depletion in current manufacturing. When this defect does actually manifest itself, those customers who bring their cars in will have the updated part installed, from the same inventory pool -- and likely won't but possibly may have the chirp return, in which case they're sure to just come back with their car...again, to receive repair parts from the same inventory pool. It may truly be that this defect is just not common. But eventually, all of the previous version parts will be consumed anyway, and this problem should be dead going forward.

It's the not-issue that Toyota and Subaru decided to not-not-fix.

About time. This one shouldn't have made it out the door.

Hopefully that makes sense. I don't really know how a Toyota part number is structured, but it's probably something like this.
Haha, thanks! That made enough sense for me to comprehend.

Hopefully these "new" old HPFP work well for the folks who experience the chirp...and crossing my fingers that those that chirped are just a bad batch.

Wait...

i just read this and it seems a bit odd or a bit confusing

Quote:
NOTE
• A mechanical ticking noise from the High
Pressure Fuel Pump Assembly is normal
during Direct Injection system operation.
• This bulletin should only be performed if
an abnormal high pitch chirp or squeak
noise from the High Pressure Fuel Pump
is verified.
so whats the difference? is there always going to be a chirp/squek noise?

Yes; 80%, but how about those who don't have the problem?

It's already been talked about... Those who don't have the problem usually don't come on here and complain about how theirs are working perfectly normal.

Ticking is normal. Chirp sounds like a loose belt on an old car. If you don't have that sound at warm idle - don't bother with this TSB.

No; they are talking about the "ticking" noise the boxer engine w/ multi-port injections naturally produces... which is normal.

The high-pitch chirping; however, is NOT.

500 (really a lower bound) cars out of a few thousand cars sold that made it to 1k miles as of yet - is still a very high incidence rate.

I do have the chirp and went to the dealer 2 weeks ago. was told it was normal and that mechanics had worked on a previous fr-s for "hours" and found nothing wrong. So, hopefully by taking this to them, they'll see that the chirp is not normal.

thanks for confirming!

This is just how part numbering works.

Like I said, I don't know how a Toyota PN is structured. It could be that the rev and the version aren't shown in the PN. The TSB would then still rightly call out the same PN, but their MRP/inventory system would certainly call for the current revision.

I would be loath to draw statistical conclusions from forum data.

My build date is 4/14, took delivery 5/29. I was down for a month for the CEL/slip P0019 cam sprocket/ECU business. The only thing I haven't seen yet is the taillight moisture. Trust me, I'm last in line to apologize for Subaru or Toyota.

By the way, the "80%" you refer to is 80% of those responding to a survey in the issues subforum specifically regarding the chirp (or the hirp as I like to call it). That's not exactly the place to build a statistical argument, for obvious reasons.

With full statistical backing I can tell you that if a survey of 10% of vehicles sold shows 80% incidence, then a true incidence is at least 8% which is already large.

So I really hope they revised the pump w/o changing the numbers. With TSB out they will have no choice but to repair'em again is this fix doesn't work, and then, after a few more tries, have to buy back those cars. Even MBA grads can calculate that it will cost dough, which is why I think they revised the pump.

No, they are simply stating what many of us have countless times during the long thread about the chirp.

The ticking is normal DI sound, the cricket chirping is not normal.

What they told you is standard practice when they don't know what is wrong with something. It makes most people go away and stay away. Dealers do not like performing warranty work, something about pennies on the dollar versus what they could charge a customer at normal rates.

I'll be damned.

I've been very clear about where I figured things will go and this was not it. I just figured chirping was going to be one of the quirks of this car. Wow, just wow.

Now here the 64 million dollar question... WHY was the TSB issued? Was it due to complaints or did they find something that actually presented a possible mechanical failure/issue?

Interdasting.

Who gives a shit why they issued it, they did! I might actually be ready to buy one now...as long as I can find one with a build date after what is posted here. I'd rather buy one with the "improved" part instead of having it fixed after the fact.
