how many people have gone to the dealer to get this fixed? Do they charge? if so how much?

I dont really have a strong dip, but i can kind of notice it.
Can i have the dealer check and see what software im running? If so is there a cost for that?

Thanks for your experience guys.

I had the dealer send my ECU off to NJ for the 4k reprogram. Charged me $100: $26.38 for the recode, $73.62 for labor.

Edit: Well damn, I didn't get a new DISA . . . I guess that's what I get for not knowing about the SIB.

What is an SIB?

Does the dealership charge for the software and the DISA?

I thought it was just a software problem and didnt really involve HW (DISA)

How long did it take to get the ECU back?

Couldnt you take out the ECU yourself and save some $$?

thanks for the Doc looks like this is an official BMW release, if i bring this to them will they know what it is?

SIB = "Service Information Bulletin", usually associated with known problems & fixes or recalls; officially released by BMW NA. Yeah, mention the SIB number to a dealership service advisor & they should know exactly what you're talking about.

IIRC, it only took a couple days to have the ECU out, reprogrammed, & back; I'm pretty sure they overnight it.

I imagine you probably could walk into the dealership with ECU in hand; might depend on the dealership whether they'd service it or not.

He ran a check on the VIN didnt pull anything up.
I showed him the SIB, he said they would have to check the car out=1 hour of labor=$125

Same thing to see my current software, $125.

The dip isnt really bad, and to be honest if i never read anything about it....... i prolly wouldnt have paid any attention to it.
Not sure if its worth going down that path with BMW.

Maybe bugging BMWNA will give me some results.
Is this the SIB info that i should reference: Engine Electrical B12 209 05 04/06/2005

I wouldnt bother with the dealer on this issue, it just seems like a dead end everytime. My vote is to go to a good indy shop and have them update your DME. It shouldn't cost more than $100 and the problem should get fixed.

I've attached it. It appears they've gotten snooty about doing the repair. Jerks!

I think there is a more recent SIB then this one. I believe they don't have to send the DME to Jersey anymore, but can do the update in house now.

Looks like they ninja edited out that little tid-bit on the DISA too, Jerks!

look into software. if you already have to spend the 125, why not hit the 300 or so and just get the shark....if it solves the problem and gives you updated software too, plus maybe other gains. Win in my book. Obviously, need to verify that first.

If it were that easy, BMWNA would be instrucing dealers to simply update the software at the dealership. Instead they have them ship it to NJ. That tells me that it cannot be fixed via a simple software update so a local indie shop will not be able to do anything to fix it. That also means that the Shark software can't fix it either.

Again, if it was that simple, BMW NA would have their dealers do it instead of going through the trouble of pulling the DMA, shipping it to NJ and giving the owner a loaner car for a few days.

Exactly. That's why I tried to ask Mr Conforti about this in Dane's thread. Never got an answer though. I just would like to know why BMW has to send it off to Jersey to fix it and if the Shark is doing the same thing with just a download? Makes me wonder if there might be actually some hardware change as well in BMW's fix. Also I've heard of some people having the dip come back after having the BMW ship/fix done. If it only costs $100 it's not a big deal but that seems awful cheap. I'm guessing most dealers would charge more than that.

Mine is like the OPs, not that noticeable so I don't know if I want to do anything about it. Last time I drove it a couple weeks ago I tried several times to get it to do it and couldn't feel anything but the temp was only 3 F so I will wait till warmer weather to make any decision.

Someone get Jim on here, the mystery must be solved.


On a side note, since the dealership is going to charge $125 to check it out, i may just head over to the local dyno and for $100 i can get my chart and see if its the normal 330 leveling at 4200 or if its the ZHP dip. Plus i will get some dyno numbers ect.

You're never going to completely eliminate a blip in the dyno curve on our motors. As to whether the Shark fixes it to the extent that the BMW 'Jersey fix' does is what I would like to know.

From the link I posted......

"Don't confuse this normal behavior for all 330 motors with the software problem the ZHP motors had at the same rpm range. Both occur because the DISA valve is doing its job but the ZHP problem was an unintended response to this event. In my case, it was extremely noticeable to the point of severely jerking my passenger's heads around when it cut timing.

The ONLY way to get rid of a slight dip @ 4k rpm is to remove the stock dual resonance intake manifold. The intake runners switch over at 4k rpm and there will ALWAYS be a slight dip in power at this point. All 330s do this, not just the ZHPs. The ZHPs did have a software problem that caused the DME to "hear" the DISA valve making noise during the intake runner transition which was mistaken for knock causing the DME to pull significant timing. This was the power dip those of us that experienced this with our ZHPs felt. I had the problem. I had my DME sent to NJ and my problem was solved. Have you put your car on a dyno since getting your 4k rpm dip fixed? I can guarantee you that even after the "4k rpm fix" there is still going to be a slight dip at 4000 rpm - I challenge you to provide a dyno of a stock 330 that doesn't have a slight dip at 4000 rpm."

Dw, I wasn't and wouldn't question your observations. I just think there is more going on here. Your testimony is why I'll be purchasing the shark.

Does anyone know if the disa uses a switching valve or a pulse width modulated solenoid? Is it two positions or infinite, like vanos?

Hey guys...taking delivery of my zhp probably next week. Coming from a 2008 STi. I've been reading up on the zhp and the small fixes, which lead me to this thread. I noticed in the warranty history the dealer gave me from the pre inspection i had them perform this service performed on the car.

Service date: 11/12/2005, Mileage: 31,322
Defect code: 0012100200 SIB #12-13-05 RECALL 05E-A01 BREMI IGN COILS REPLACEMENT
Defect code: 1214151100 Component, DME control unit occasional failure

MrMaico
04-14-2011, 11:40 AM
Going by that date (Nov 05) I would have to say no, it probably doesn't have the software to cure the 4000 rpm power dip or the one (latest software) that cured my 2800-3000 rpm miss. I believe that there should be some mention of it having been sent out (to NJ) for the 4000 dip fix. And the other update was for a problem that surfaced on cars after the O2 sensors got older so this probably wasn't even known about that long ago. But this is all just a guess based on limited info. That second one I've never seen mention of before.

The second Defect code I believe means the DME was either replaced or fixed. I guess i don't follow why the Nov 2005 service date would rule it out since the last SI B was released in Sept 2005. It seemed like a good correlation, but that of course means nothing solid. I'll just see how she drives.

What I've found is that the software update fixes the pronounced dip at 4k by pushing more fuel to overcome the Anti-knock Sensors from over correcting.

Yeah what has your experience been since then? You say in Danes thread that the fix causes your DISA to be open all the time now. Is that really the case?

If so, doesn't that mean you are losing low end torque? I though the point of the DISA was to aid in low end engine performance. Not sure I want the fix if it defeats the DISA.

Honestly I cannot really tell. Since I'm used to faster cars and their monstrous torque/hp, I can't really say for sure its fully gone but it definitely doesn't feel like a dead spot anymore.

I think what happen is BMWNA turned off my DISA. I concluded this because we did some analysis with 4 ZHPs when I was at the dealership.

2 non-PUMA updated ZHPs
2 PUMA updated ZHPs.

The non-PUMA updated ZHPs showed their DISA actively close during startup and idling. When revving, the DISA moved and opened. DISA function test showed no problem closing and opening the valve.

The PUMA updated ZHPs showed their DISA valves to do nothing during startup or idling. When revving, the DISA valve did not move either. DISA function test shows no problem closing and opening the valve.

Granted it was a small sample size but I am led to believe that either BMWNA forced the DISA valve to be open permanently or it has new functions that did not allow the DISA to operate during stationary reviving.

Either way, my guess is the DISA no longer functions and remains permanently open. A loss of low-end torque at the sacrifice of no dip. I think I would need a few more ZHPs to test this case but I would probably need a Dyno or a GT1 running while someone drove around.

It's possible. I have no real immediate proof beyond the mundane test I manage to do on 4 ZHPs at the dealer. Only real way to know for sure the DISA is working is to monitor while driving the car. I would need the laptop connected and set to read the DISA valve status (if there is even a realtime one available.)


Honestly the 330i feels slow to me so I can't really say the "lack" of low end was noticeable. To be fair, it probably has a lot more torque than the M3 has under 3K RPM.

NorCalZman
07-15-2014, 04:41 PM
Hmm. Interesting info, thanks. Wish there was a way to test the DISA while in motion like you proposed.

The ZHP is all I have so it doesn't feel slow to me :-). Having said that, I would rather keep my DISA functioning since I spend most of my time below 4k rpm

If you ever figure something out and need a "control" car without the fix we can use mine.

Hmm. Interesting info, thanks. Wish there was a way to test the DISA while in motion like you proposed.

The ZHP is all I have so it doesn't feel slow to me :-). Having said that, I would rather keep my DISA functioning since I spend most of my time below 4k rpm

If you ever figure something out and need a "control" car without the fix we can use mine.

When I plug in my car next time I'll look through GT1 for Disa monitoring.

Hard for me to believe that DINAN found the "ever so elusive" fix, while some other "very smart people" haven't.

Not doubting you, just sayin.

You can come drive my car ;). My car use to have a very noticeable dip around 4k, you could feel it with your arse! Now you really don't feel anything at all. I assume Dinan had updated/designed the software to work with the newest E46 DME software. Or they updated it when BMW did. I'm interested to hear if JOOP has the dip.

Turning off the DISA would eliminate the dip we feel, but it means the whole lowend would drop too LOL

Sounds good. Fingers crossed it will be that easy.

I can do it cheaper than DINAN by just unplugging it.

Hah. You want to try that experiment Dane?

Sure. It's not going to hurt anything. I think it fails open though, so low end torque won't be there.

I'd love to hear someone's impression without the DISA. There was a guy on e46f who swapped an M50 manifold on his M54 which ultimately led to a DISA delete. He gained 10+hp and lost around 7ft/lbs peak torque between the 2.5-4k range. Obviously would be great for a track car, but I wonder how noticeable it would be on the street.

Right. We are wondering if having the DISA open will a) lose noticeable amount of low end torque and b) eliminate the 4k dip.

I would try myself but my car is in storage as it is most of the time.

I would rather have a working DISA lolz. And what's up with everyone saying Dinan is expensive. The tune isn't anymore then any of the others available :dunno. Anyway if anyone else has the tune please comment to see if you can still feel the power dip.... Cause I can't.

I thought it was actually closed on low-end to allow it to use the long runners for better torque.

That is true. It closes when you start the car and at lower rpms. If unplugging it gets rid of the 4k dip that will be interesting. Then if we can figure out if yours stays open due to the fix, then we might conclude thats what the "fix" does to get rid of the dip.

I think I've figured out the cure for the dip......s54 swap :ninja

Mine doesn't close on startup. With no actual change to short runners, you will definitely never feel the dip hahah

This is the true solution but you lose alot of low end in the process too ;)

I think it used to be way more. They reset their tune prices later than the others.

Yes but they have been the same price for quite some time now and it's really inexpensive when compared to some others. Just saying. Plus free software updates for life! (Not that I expect them to release any lol)
