When I worked at the State level for an Engineering agency, they would get pissed with requests like these ..... this request is very complicated, very long and requires a huge amount of man hours.

The fines per day are real and the last thing M would want is to make the papers on this as they are not the company in focus.

Hats off to NHTSA.

Sorry that Mr. Benz has to be brought into, but all the better.

M. will essentially tell everyone that there is NO ISSUE with the way THEY DO THINGS.... which will include them dispelling the BS that is poor US Fuel, OR at least noting how they overcame US Fuel issues.

NHTSA will then be able to squarely come back to VW and say, US Fuel is not an issue, gas should not cost 8k to recover from, fix the pumps.

Interesting, although it looks like the affected pump was the CP3.3, which isn't what's failing on US fuel.

Would that be a Micro-mini bus? Since GM and Ford are seeing hpfp pump failures with their Bosch pumps, I wonder if they will also get this request.

those failures are so small in comparison and even from what i've seen probably half are water/fuel contamination.

interestingly they already have a tsb at ford with instructions on various steps to diagnose hpfp failure

I wish we would know more about what was causing the failures of the BMW CR hpfp pumps in 2005. To me it sounds like a manufacturing or materials defect. The only details we have is that the cp3.3 had dramatically shortened lifespans. The answers to this would probably answer all of our questions in regards to the CP4.1 pump. Although it's not the same pump, there is a good chance that similar problems are causing the shortened lifespans.

CP3 pump, I think, in the MB, lubed by crank oil or something, on the cam lobes surface, not D2. Maybe Drivbiwire can comment.

That number after CP is the generation of Common Rail pump in the Bosch lineup. Ours are CP4

the CP3 was problematic even while being lubed by oil. Bosch fixed the problem and since then they've been problem free. That's basically what needs to happen now with the CP4.1 I don't believe the CP4.2 has shown to be problematic enough to warrant a fix yet, but if whatever is causing the .1's to fail is also being applied to the .2's Then they might as well Recall them both.

Is there any place like NHTSA in Gremany or Europe that would have details that caused the recall? Although even if we have that information, it would probably not tell us how the BMW pump was redesigned.

this may be the reason why they're getting information from Mercedes as it may refer back to this incident.
Yes, it may.

If I could read German I'd probably be able to provide a more thoughtful answer.

Any more foreign language links you'd like to share?

With the help of Google Translate, I'm getting the following out of those articles (guessing based on some context, when there's mistranslations):

First article: BMW stopped production (about 3600 cars were delayed) and recalled cars due to HPFP lifespan being shortened, and it affected DaimlerChrysler and Audi as well, although Audi didn't stop production.

Second article: DaimlerChrysler stopped production and replaced that production with gassers, Bosch claims that a vendor's coating failed, C, E, and S class are affected. Audi only had problems with certain batches. VW's only affected vehicle was the Phaeton. Opel's 6-cylinder engines aren't affected due to using a Japanese pump, but their 4-cylinder engines use a smaller version of the affected pump (I'm assuming Bosch CP3.2 vs. 3.3, here). Opel did testing, though, and hasn't found any problems.

Fuel Economy: Is just one piece of the puzzle that is our bottomless appetite for oil. Cars donít have to be consumable. Instead of throwing them away, we can rebuild them, better. We have the technology.

Thanks for the translations. Looks like Google translate is a work in progress.

Or should I say looking to be progress in the translate would be working even now.

You are probably referring to the patriarch Ferdinand Porsche (sorry, you missed his birthday) or Ferdinand PiŽch (you have a number of months ahead of his b'day to plan a protest ). Better to go after VWoA CEO Johnathan Browning (June 21st), VW Group president Martin Winterkorn (May 24th) or VW Group Executive Director of Powertrain Engineering Wolfgang Hatz (d.o.b. ?)
Well, "OVA" could conceivably be swarming the streets of Herndon for multiple passages of these dates, awaiting a suitable response...
