That's why I'm asking pump leak victims to find out if dealers are replacing these with conventional, non-variable pumps. There are reports that that is the case and there appears to be a TSB on it, which makes sense with such a potentially disastrous failure. If true, it would be a shame to lose the extra quick warm-up feature of that pump, though, and as such, its probably considered an integral part of the emissions system. Perhaps an improved variable-flow pump is in the pipeline and a conventional pump is just a stop-gap measure until the redesigned one is available.

I wouldn't hold my breath, but there's hope.

Id rather have no variable anything. Straight mechanical and no electrical. If your at 70000 miles and the variable water pump dies ya just as well do the whole TB job cause it would just cost alil bit more for parts.

When I have time I am going to pull the underbelly and see if I can poke a borescope up inside the timing cover anywhere and look for red stains. I was able to find a small leak on my Powerstoke this way before it got bad

This failure would, of course, cause overheating. Don't know whether early pump external leakage would contribute to this sleeve seizure at a later date.

And the service training pdf assures that this won't happpen

This ^^
Reminds me of the variable adjusting suspension they put in the Lincoln. Good intentions but poorly engineered - designed to fail and costly to repair.

Which dealer did you take it to? Northtown, Towne, Basil, or Orchard Park?

Just got my car back from Basil. The new pump which they said took longer to receive than expected is 04L-121-011-L. The service writer didn't know the difference between variable flow or constant flow and said he did ask the tech. I have 39010 miles on my odometer, fully covered no charge repair under normal powertrain warranty. The car heats up normally.

2015 Golf SW TDI. My tank was low a few times. They found a crack in the side of the radiator tank on the left drivers side. Replaced in for free, no more problems, maintains level between the low and normal line.

Northtown, Towne, Basil, or Orchard Park? Reviews run 10% unhappy for every dealer around here.
Please let us know if you notice any longer warm-up time due to the non-variable pump. Are you still under the 3/36 warranty?

Actually we still don't know which pump that is. Whether that number is already a super-cession or the part is a redesign without a new p/n isn't clear. Dealer online parts catalogs only list 04L121011L and 04L121011EX which is the same part but rebuilt vs. new.

Only a visual would have confirmed which pump this is.

We had the red triangle show on Thanksgiving day... while already late. Checked coolant and it was a hair below the sensor. It only makes an appearance on cold cold days after the vehicle has sat over night. I just ordered an oil change kit and coolant from IDPARTS to top it off. I'll keep an eye on it from there. 28.5K on ours. Need to go to the dealer for the passenger side rear window being INOP, I will have them check it at that point.

I did the 20k and will do the oil soon so this doesn't see a dealer often.

I have 39010 on the odometer. Repair covered under powertrain warranty. Warm up time seems normal.

I've only taken car to where I bought it from, Dorschel in Rochester. They've treated me pretty decent so far. They gave me a loaner for the phase 2 fix, wasn't sure if it was gonna be complete or partial, ended up being partial plus horn replacement, and didn't charge me for loaner.
