N55 Wastegate rattle-anyone else with N55?

tizzyd · 06-08-2010, 07:20 PM

Anyone with the N55, does your wastegate rattle really bad on cold starts and at random times? Mine does, and it is super annoying.

TMR · 06-08-2010, 07:31 PM

WTF they still haven't fixed that!!

mycoupe · 06-08-2010, 07:34 PM

Bwahahahahaha!!!! Now wait for the HPFP to die too! Stoopid BMW!

Clap135 · 06-08-2010, 07:58 PM

BMW has turned into the biggest pile of shit on the road.

mkiv · 06-08-2010, 08:00 PM

feel sorry for the op.

5soko · 06-08-2010, 08:44 PM

Sucks to hear, can you take a video of the sound you are hearing?

Also I heard that the N55 has the same HPFP as the N54 currently!! And someones N55 already failed on this forum, i forgot the guys username.

lawwailok · 06-08-2010, 09:28 PM

no shit?!!?? sorry to hear that OP, how many miles do you have on the N55 so far?

Whaaaaaaaaat?????? You would think that with the N55 there would be improvements over known issues.

Maybe BMW should've just kept refining the N54 and release an N54TU (though I don't think they use the "TU" anymore). And I'm not talking about slapping on a BMW Performance Kit with an overboost function to the current N54.

Sorry for OT:

TrackRAt:

"The N55 engine uses the same 943 HPFP as the N54 engines. This has been documented. The latest N54/N55 replacement HPFP is a re-manufactured HPFP under P.N. 1351-7-613-933. The 943 HPFP is no longer avilable thru the BMW parts system in the U.S. The 933 re-man HPFP is all that is available"

As for the OP, i hope you can get that video, i am interested to see if its really wastegate rattle so early on... I would either way dealer it and see what they say, but would love to hear it as your the first.

damn, long ride. How was all those bugs you killed getting back.

I'll lke to hear the sound as well before you take it in to the dealership as well. Is it random or all the time at start-up?

I gotz the 943 last week. So its still around I guess til they clear the shelves.

zenmaster · 06-09-2010, 07:21 AM

I also got the 943 last week.

DaveinSF · 06-10-2010, 06:06 PM

I've only had mine for about a week and 300 miles, but no rattles so far. I have been pleasantly surprised by how fast and smooth the new engine is. At this point, I wouldn't be surprised if the new N55s are faster than the stock N54s...

Nahhhhhhh! Just kidding the dct will help a lot in getting the power to the ground hopefully the tuning potential is on-par with the n54

Mike@N54Tuning.com · 06-10-2010, 07:00 PM

No rattle on BMS' 135i but plenty of lag stock. That was one of the first things they fixed up.

That's just wishful thinking plus you have a N55 engine so ofcourse your going to say that

. IMO I think the N54 will be much superior to the N55 but that's because I have a N54!!!!!!

That's the problem. Too many ingenierus and not enough engineers.

cstavaru · 06-11-2010, 10:33 AM

I don't believe the HPFP is the same in the N55. This would mean that the failure is caused by other things like too much pressure, dirty gas, etc.
