The Random E46/ZHP Question Thread

[alexandre]

Whenever I'm shopping for parts, or I need quick spec on something (torque, part number, OE brand, etc), I don't really have a place where to ask on the forum.

For example, yesterday I needed to know what voltage our alternator was supposed to output at idle but couldn't find it without Googling for half an hour on my phone. Answer: 14.0V +/- 0.2V on new components and healthy engine.

I've been looking for such a thread forever, but couldn't find one. So here is the random E46/ZHP-related question thread, where repeat questions are welcome and "just google it" isn't the answer.

I'll start:

Do most ZHP's have hydraulic serpentine belt tensioners ? What's the production date cut-off if not ?

[Avetiso]

I've thought about this type of thread. Glad to see I'm not the only one.

The only way to find out is the look for the hydraulic unit. While I am not sure if they came with mechanical or not, I would imagine if any E46 came with a mechanical, they may have changed over to the hydraulic unit. It is likely that many have changed over since many E46s are now pass the cooling maintenance period. It is best to check.

To my knowledge, there isn't. The only way I could tell what mine was by pulling it out and looking. Glad I did it while it was out, too.

I'm looking for a replacement PS res, but the one on ECS Tuning says "For use with CHF"...

Can anyone get me a P/N for the one for use with ATF? It probably doesn't matter, but I just want the cap to say the right thing, and the one on ECS is wrong.

[Avetiso]

BTW, Alex, perhaps recommend that everyone subscribes to this thread? If we all commit to check and reply to this thread, it could become a fantastic utility.

You could reuse the cap and just change out the seal. #32411128333.

I figured maybe cars after x date came with strictly hydraulics, but info on the web does seem fuzzy.

I have neither in Canada haha. I doubt it's this as it all electronics work perfectly once the car is started and battery voltage doesn't go down. It just measures as 12.3-12.6V at the battery so I figure it's something with the circuit from engine bay to battery.

Use the service menu in the cluster to read the voltage with the engine running. If it's not 14V it's most likely your alternator.

[alexandre]

Yup that's how I do it. But if it wasn't putting out enough voltage, my electronics would run off battery, yet this isn't happening... Hence my loose connection hypothesis.

I'm confused. It's reading 12V at the battery and 14V at the cluster?

[ryankokesh]

Alternator will put out 14v to charge, so that's what you're going to see while the car's running.

[alexandre]

Nope 12V at both. But the cluster reads off the positive terminal of the battery if I understood correctly.

[jakksfor20]

At the very least it could be the voltage regulator attached to the alternator. A loose connection would be showing some more intermittent issues and frankly some not so friendly ones (i.e such as when you disconnect/connect your neg battery terminal).

Any large chain parts (Napa, Carquest) stores should be able to test your alternator and battery.

For people who have done starter DIY:

Does the positive cable that leaves from the voltage regulator go directly to the starter or somewhere else ?

If I remember, Xenon uses 35W and Halogen uses 55W.

Foglights should be the same as the halogen at 55W unless you guys change it from stock wattage.

Yes, that's what I mean. And I'm surprised that the options xenons weren't included on the zhp. Lay out an extra $4k for the performance package but not a few hundred for better lights? Just seems weird. Even my "lowly" 325 with just ZPP had xenons.

It was actually a $700 option. It's not easy to deal with coupe lights so don't retrofit, just try to find a wrecked facelift coupe and swap the assembly complete.

Reprogramming the car to have Xenons will be good. Just have to make sure you either put in the auto-leveling or disable it in the coding too.

A lot of times you hear about people bore and stroking their engines to gain power. Why is this never the case on an M54? I don't think I've heard anybody doing that much.

I don't know much about engine internals :(

[QC_ZHP]

Probably $$? I'm not sure of the exact costs, but it seems once you get through the cost of machining and new parts, may as well have done the s54 swap and open a whole new door of potential power for the same coin.

[derbo]

Another thing is high rev is severely limited with hydraulic lifters. M54 can't rev that high but we don't need to do valve adjustments constantly.

sent from Moto Dev edition

Yeah, it's just not cost effective. It's simply smarter to drop in a better engine.

I'd love to drop in a Yamaha 3.0 or 3.2 that was used in the older Ford SHO's. Those things can be built to rev to 10k reliably. It would be beautiful.

[stephenkirsh]

Makes sense. I guess it's probably the same answer for bore/stroking an S54?

Coolant is the only fluid with that exception, however, I know plenty of people who run green fluids in their cooling with no issues at all. It's not as big a deal as everyone makes it out to be.

I went with Valvoline Dex-6 ATF from Reilly. Paid $17 for two quarts, and flushed both of them through the system.

Yes the one I received was OEM. If you type the part number in it isn't the special pricing. You have to click the one for $245 and enter your vin so they can send you the correct part.

Ooooo I found an automatted calculator.

http://bndtechsource.ucoz.com/index/tire_data_calculator/0-20

According to my numbers and their calculations, the front wheel on the zsp has a slightly larger contact patch, unexpected. The rear contact patch on the zhp is slightly larger, as expected.

[derbo]

Actually it also even varies from manufacturer specs. :)

Contact patch sometimes measured as tread width but since most contact patches now are more rounded, its hard to say when the actual start of the contact patch is. There is no standard on how to measure tread width. The only thing you can really measure with a standard is section width which is the length from the edge of inner sidewall to the outer sidewall. This doesn't really give you what the contact patch is though..



Tread width comparision..

255/35/18

Dunlop star spec II , tread width 9.6"
Bridgestone RE11A , tread width 9.4"
Hankook RS3 , tread width 9.5"

pulled from Tirerack specs.

[derbo]

Really not sure. I didn't have time to pull them this w/e. I did turn them on in the daylight and looked at each bulb. At night one is definitely dimmer. Looking directly into them they both looked the same. Sound like a burnt bowl?

I would swap the brighter bulb to the other side to confirm it is indeed the bulb. If it isn't, you gotta work a little more and swap ballasts.

[Johal E32]

Yup that's correct. Any idea on contact patch size? I don't know how it's calculated.

the 40 in 255/40.18 means it is 40% of the 255MM sidewall.

so the 40 in 245.45/17 means 40% of the 245mm sidewall

so the 40 in 245.45/17 means 40% of the 245mm sidewall


The 225mm is the section width of the inner sidewall to the outer sidewall and the 40 is sidewall height aspect ratio. The sidewall is calculated to be 40% of the section width.


Section Width

Following the letter(s) that identify the type of vehicle and/or type of service for which the tire was designed, the three-digit numeric portion identifies the tire's "Section Width" (cross section) in millimeters.

P225/50R16 91S

The 225 indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the section width in millimeters by 25.4 (the number of millimeters per inch).

225mm / 25.4 = 8.86"

Sidewall Aspect Ratio

Typically following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.

P225/50R16 91S

The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall.

I would swap the brighter bulb to the other side to confirm it is indeed the bulb. If it isn't, you gotta work a little more and swap ballasts.

1) E46s headlights were built to perfectly accommodate AEs. Why didn't BMW put them in when the older E39 had them? Plus, the ZHP package didn't even include it. It would at least make some sense if BMW sold them separately as a BMW Performance part but they didn't do that either.

2) Why no one-touch open/close rear windows for the coupe? The front windows do.

3) How do you reset the Bluetooth or connect to it? I know that there's a serial number with the PIN on the unit in the trunk but that's not what I'm looking for.
The previous owner used it and I somehow was able to find out the PIN (not from them) and connected to it with my old phone. But I have a new phone now and forgot the PIN, and am trying to remember/find out if there are other ways of resetting/obtaining the PIN without taking anything apart.

4) Are all ZHPs Sirius-XM enabled? Sometimes when I turn on the radio, it reads "Sirius" for a brief second, then goes to regular FM radio.

1. no they are not. have you every seen the inside of a headlight with OEM angels? all you see is the front which are just the fiber optic tubes. in the back, there's a ton more stuff to make it work. there's not enough room in the headlights for it hence why we have the LEDs now that aren't uniform. even the old school ones that tried to mimic it had no where to but the light boxes, so you would have to mount it outside of the headlights.

2. they do have it for euros. we americans are too dumb for it and are too sue happy. they took it out. but you can buy switches and enable it by coding. or modify your switches to do so.

3. no clue. probably involves taking shit apart lol or unless you have your old phone, maybe somehow view the pin on that.

4. i don't think so. i think you need a specific module to enable the functionality.

[KevinC]

If you're seeing "SIRIUS", then I'd think you must have the tuner for it. Get the Bluetooth code off the module, not sure where it's buried in the back of our cars. Bluetooth actually works pretty well in my car, other than having to use the tiny display on the stock head unit, which is pretty useless for scrolling through a phone book. But for incoming calls, it works well. Can't say the same for my Z4MC, it's almost useless.

[JKO_ZHP]

Hieu & Kevin, the 4-digit PIN number is on the unit in the trunk, but I don't want to take off the headliner and unscrew stuff. Too lazy hehe
ELCID it's neither, all ZHPs that do have Bluetooth enabled have unique PINs. Or else people would be (able to) connect left and right whenever you put it to "search."

I miss the Bluetooth function....for an '05 car, it was pretty damn useful and futuristic. I remember saying "dial" out loud, and the car would ask for the number. Or "phonebook," then "call ___" and my phone would be dialing that person.

[slater]

how do you setup the bluetooth pairing? i have an '05 coupe...

peter

[sillieidiot]

oh yeah i know where the pin is located. i was just saying i don't know how else you can get the pin without going to the trunk and taking off the liner lol

i don't use bt at all. my phone just uses the aux input like it's a headset. so to me it's the same thing. except if i want to talk to it, i have to press on the phone first

[wsmeyer]

Yup that's correct. Any idea on contact patch size? I don't know how it's calculated.

In a textbook example it would be easy, the owners manual lists:

Weight: 3285lbs
distribution front / rear: 50.1% / 49.9%

At the recommended inflation of 35psi front, 42psi rear you get:

FRONT: 3285 * .501 / 2 = 822.89 lbs per wheel
822.89lbs divided by 35lbs per square inch == 23.51 in^2 contact patch

REAR: 3285 * .499 / 2 = 819.61 lbs per wheel
819.61lbs divided by 42lbs per square inch == 19.51 in^2 contact patch

If car tires were made like inner tubes it really would be that easy to calculate. We want our car tires to be flat on the bottom though so they have steel or Kevlar belts in them to help hold that shape and you end up with a significant amount of weight being physically supported by the sidewalls. If you really wanted to know the contact size and shape you'd have to lift the car by the wheels, paint the bottom of the tires, lower it onto cardboard, raise the car back up and then analyze the patch.

[JKO_ZHP]

how do you setup the bluetooth pairing? i have an '05 coupe.

peter

Not all E46s came with Bluetooth - what I've heard is that the coupes all have the buttons on the steering wheel for it but that doesn't mean it was ever enabled or functioning. My 2005 325Ci had the buttons but no Bluetooth.

With that being said, the easiest way to find out is to press the R/T button on top of the one with an icon of a head that's speaking. If you are Bluetooth-enabled, the radio should read "searching." That's when you would use your phone to search for the connection, enter the PIN, and you will be linked from then on whenever the car is on.

[JKO_ZHP]

peter

From what I've heard/read, most if not all E46 coupes have the R/T and Bluetooth button on the left side of the steering wheel.
Whether or not it's enabled/functioning though, depends on if the original owner purchased that option.
My 2005 325Ci did not respond when I pressed those buttons. But for the 330Ci, pressing the R/T prompted the radio display to read "SEARCHING" and that's when I was able to connect to it using my phone.

You can check by pressing the R/T button, or the Bluetooth button (a face talking, it's right next to R/T).

I switched out the stock suspension on my former E30 and ran Koni yellows with H&R Sport springs. I didn't want to make the ride too harsh even though the car was supposed to me more track-biased. Drop was acceptable over stock, yet still allowed me to clear most speed bumps without issue. FWIW, I do not yet have Koni's on my ZHP, but I will certainly add them in the future. Good luck hunting down the ideal suspension setup.

It lists a good number of different sizes/specs for the style 37, so your best bet will be to verify exactly what’s stamped on the wheels’ backsides.

Not sure about those choices.

I'm running Pentosin in my tranny and Redline in my diff FWIW.

Do you like the tranny fluid?

I thought redline was the go-to fluid for tranny and diff?

Sent from my SM-N900T using Tapatalk

I think I will just go with redline. It is tested and well liked!

OK. Looks like you've made your mind up.

On second though.. Lol. Redline for my diff is settled but tranny... Hmmm. How's the fluid you are using? If I recall correctly you have had experience with many different fluids so spill the beans! :)

I've ran the Royal Purple, Red Line, and Pentosin in my ZHP.

I rank them:

1. Pentosin
1. Redline
3. Royal Purple

Have a ball.

Terra ran the Pentosin in his, and had positive things to say. His experience was good enough for me, and I'm glad I went that way.

Though I don't think you be doing a bad thing using the Redline.

I'm running pentosin in my trans and redline in my diff. BMW told me to use pentosin in my trans based off the sticker on the side of it.

I highly recommend you do not use royal purple. If I remember correctly, Keith put it in his trans for a little while and sent it to Blackstone for analysis. Blackstone grilled it suggesting to immediately take it out because it was causing damage.

Lurking around, I believe it's time to change the trans/diff fluid.

Just a few things though....
1) I asked my guy about Pentosin and Redline. He asked what specs for Pentosin (guess I'll have to do some more digging) and said Redline for the diff is a waste unless you are tracking the car. I have no idea what this means but he did say it's like getting R comp. tires and only commuting with them. Looking back I guess this means it's not cheap....? And there's other alternatives?

2) Same fluids for manuals work with autos?

3) What's the general consensus on when to change the fluid? Based on miles or time? I know most of us change our engine oil anywhere from 3,000 miles to 7,000 miles with 3k being the more conservative (PREservative) end but what about the trans/diff?

4) Flush or just change?

[Pip]

Well there are lots of options for the diff and redline is a popular one. If go with Mobil or redline just because availability and quality. For the ATF I strongly urge OEM, but that is expensive and hard to find. The new fluid BMW is selling is remarked dex6. There are many auto guys here that have used redline atf d4 and been fine. My tranny didn't like it so much. Not sure how many miles you have, but I'd change before 60k if possible. If you wait not a big deal because Gary and others have higher mileage autos and have done the fluid change late in the game. As for flush or change on the ATF do the change. You will be dropping the tranny pan and putting a new filter in so about 7-9qts...I think.

[Pip]

I think atf every 30k after your first one and the diff every 50kish? Dane has a pretty good log or maybe it was the Mike Miller sheet.

[KevinC]

My indy just changed the trans & diff fluids in my Z4MC, and used Redline in both. The differential lube was kinda stupid-expensive, but hey, in that exotic locking diff, I figure I should use the good stuff.. even if I mostly drive it like an old lady (well ok not MOSTLY, but...).

I've done 4 of them so I can probably do it in about 45 min....

Maybe 1 hour for a first timer.

Might be in that same boat with you Shawn, my left front one does the same thing. Was looking at the zip-tie method but saw a thread on here from awhile ago where someone (dane?) basically said to just go ahead and replace the whole thing since you will have already taken apart the door at that point anyway.

Correct.

I did Zip Tie my new one though to help it last longer.

What is this connector? Right side of trunk, is bundled to the smaller positive battery cable. Two of three pins populated in the connector. I found something similar by one of the seat belts when I had the interior out.

According to previous posts I think it had to do with shipment of the cars from Deutchland.

What spark plug would y'all recommend for my zhp? Given my future plans of transforming this into a track/street car. Next mod up will be headers and eurocharged

How many liters of brake fluid is needed for installing new lines/fluid flush? Is it just one liter?

Yes, I usually have leftover. You will need to go to the dealer to have them cycle your ABS to get the last of the possible air out of the system since you're replacing lines

[johnrando]

Why do you say the dealer JP? You can do it via a computer (I think Willliam did this) or couldn't you do that via Indy?

Yup. Used INPA and followed the ISTA procedure for bleeding lines after I went to braided.

Tough to tell by looking at a pic. If you're >100k miles, it most likely should be changed.
