Yeah, I was thinking about that also.
But they should go ahead :
1/ who knows about this new BMW pump
2/ the community will need a reliable HIGHER flowing pump for when we go over 450whp.

Do they necessarily need to upgrade the software if the new 943 pumps are used? I would like to keep my software the same as IMO I think the earlier versions are the most performance driven...

What's your point exactly, Mr. Smartypants?

I highly doubt that's how the system works. There must be more to it. Otherwise, what you're describing makes heel-toe driving impossible. I do that on my car all the time and engine doesn't just return to idle...

I tend to think the very latest is "the most performance driven".
I recently was upgraded from the pre 24.1 to the latest and my car has never felt better and exhaust is louder.

There is more to it but I am not sure what. I have tried this and if you are going on the road and you press BOTH the brake and the accelerator the car will drop to idle and come to an easy stop. If, on the other hand, you are at a stand still and you press the brake and the accelerator the brake will hold as long as it can and then the rear wheel(s) will start to spin and the tires will light up. I have not gone so far as to see if the engine will eventually overcome the front brakes too.

Still one would hope some consumer advocacy group would come along and take this up. A car with a failing part that we may be having to pay for countless times after warranty period is over is still pretty rediculous. A working part is needed, period. You have to wonder, why cant they just do a test mule and drive it all over the states and fill it up with diffrent gas and stuff and see if they can replicate some problems. Heck, pay me and Ill drive the car BMW.

Gotta love internet language

First, the thread wasn't about Toyota. You guys hijacked the thread to something else. The original purpose of the thread was to advise the new pump that ends with 943 and is available from Tischer.

You guys having too much time and started the thread to something else.

Save the bandwidth. Or, post another thread and advising that BMW is failing like Toyota does. Don't fscking hijack other people thread!

Read the sticky. It has all the information you need to know about why 881 still in use, who has filed lawsuit, who has filed what with NHTSA.

And my post wasn't directly to you to start with

[Clap135]

For those who care my 09 ate through 2 881 pumps so far. It is at the dealer as we speak and i just got a call from them. The are replacing the pump, the low flow sensor and the ecu is getting reflashed. The SA was unsure about part numbers as the car was being worked on. If i get the 943 pump, ill keep in touch. If not, then this pos will fail in 3 months anyway.

I disagree. I have to think anyone who seriously wants to push >400whp will run methanol at which point the meth will handle the additional fueling. IMO, meth is the smart way to handle additional fueling, difficulty of sorting a new fuel pump aside, as the N54 has a pretty high compression ratio (10:1). Meth/Water injection basically makes the engine detonation proof, allows you to make power with timing, and lowers egts (all else equal) which makes life easier on our snails. Just all around a good idea. I think meth would be a good idea even if our cars were PFI and we could just source a good walbro pump.

EDIT: oh yeah, meth keeps your engine clean and sorry that jacked the thread.

I would assume you have meth installed on your car!

As if you and I don't LOL.

I really want to like a 335i or 535i because of the mod potential but this HFFP issue drives me crazy.

BMW needs to rectify this by posting a recall that actually fixes the issue i.e. a pump that will not actually fail, and extend the factory warranty for all effect cars because of the issues and hassles the old FP caused BMW owners.

Warranty has been extended on all cars so far except 2010's which will come under the warranty extention next year if the problem is not fixed by then. They are working on the problem and I believe that they are doing so seriously. They have 100s of thousands of customers at risk and they will lose them if they do not take care of them. They know that.

[jt335i]

Hmm. I bought mine on Dec 30th 2009, but it was built in October 2009. I wonder if the dealer replaced the fuel pump while it was still on their lot?

I would bet the world the answer is no.

Which is a reactive approach instead of a proactive approach that they should be taking aka RECALL to actually fix this problem.

They may be trying but they are not trying very hard.

I am cross shopping a m3 and m5

but if they actually had this issue sorted out I would have no problem picking up a 335 or 535 and get a dinan tune and call it a day.

If they are going to do a full recall to these new pumps, they might be waiting on 2 things:

Let them get tested in the field for a bit
Get tons of pumps in stock and ready to go

I doubt they have enough of these new pumps to recall everyone yet. It is hard enough at first just to keep up with the ones that are failing already.

[VTGT]

Any official BMW updates on this?

Anybody know if there is a long term fix for these fuel pump's yet?

Even if there is an aftermarket solution that completely eliminates this failure I would have no problem purchasing a 335/535i. However I have not read of one yet.

[Fuel&Fire]

The pump has barely been released, and I dont think anyone has had one installed long enough to report. Most are still getting the old pump until the stock are depleted.

[BMWfan07]

I had my HPFP replaced at the dealer yesterday under warranty. The towing company flatbeded it there before they opened and I called them at the opening and asked if I would be getting the new improved HPFP. The SA replied, "Oh' yes, You will get the latest greatest". When I picked up my car at the end of the day, it had the 881 part number listed on the invoice and he was busy and I could not ask him about the part number used.

The SA was full of crap and like many, he knows not much about his job. I have to know my job very well and perform it well too, I am continually amazed that many SAs don't seem to know much about the brand and its model's issues, etc...
