Hello, everyone.
Yes I have the M56 also, with 65k
I always fill her up when it gets bellow half a tank . Always shell or moble .
I also threw in some moly lub gas treatments lol
The purpose of preserving the tank is to keep it cool.
If im not mistaken warranty is 15 year or 150k

For the radiator, if you are out of warranty just replace with a standard e46 radiator as it will fit perfectly fine. The only difference between the two I'd that our original radiators came with a special coating aside from that they are the exact same.

Apparently the SULEVs run a 5 bar fuel system like the M3. So if I had a sulev and wanted to convert tanks, I would install the M3 fuel pump and fuel regulator.

I just got my fuel pump and tank done under warranty. I had a misfire around 70 mph on the freeway and I took it in to the dealership and they took care of me no problem. I had a sweet loaner car for 4 days then got my car back and now she runs like a champ!!

California emissions warranty. I feel a bit lucky it happened before the 150k. Im at about 111k so Im happy as a clam. 6,800 dollars worth of parts and 2 and half days of labor. Im scared to know the total cost. all that work done 100% free. I did not pay 1 dollar. Life can be nice to us some times

Shoot, forgot to update this thread. The idle surging issue is gone. I replaced the OFHG, VANOS seals + anti-rattle bearings, VCG, and a new VANOS oil line.

Upon removing the VANOS oil line, I noticed someone had doubled up on the washers on each side of the banjo bolt. I corrected the issue, but am wondering if the extra thickness of the washers placed the hole in the banjo bolt in a position which starved the VANOS of oil possibly causing the idle surge.

Wagon is at 128K now and running like a champ. Need to find a reason to bring it to the dealer and have 'em swap out the tank before 150K rolls around.

Crack up. If there isn't a problem with the tank then theres no reason to attempt to replace it.
My advise is just be honest, Pay the hour rate and have them check it.

There's nothing to check on the tank, they will replace it under warranty after a diagnostic is being conducted by their technicians, also first they will read the car key to check the history and milage of the car when they find out the the car won't start or low pressure they will replace it.

Makes sense, sorry for misleading.

After having found out about the SULEV issue, it really does trouble me. If I had known about this when I bought the car (2004 325i) when new, I would have insisted on either a manual or just coughed up the $ for a 330 automatic. That being said, so far, so good at 129,800 miles (mostly highway). But I'm already dreading the day 5 years + 1 happens, or 150,001 miles, and the fuel pump hasn't died yet...

Mine didn't die but I replaced it with a tested 100$ used one when I had symptoms. Later found it to be my intake cam sensor wires frayed. But, I now have a spare fp for that day it fails and I also found out my pf appears newer then my used one. So good to go. Maybe you should grab a second one for that day, ahead of time.

Where did you find yours? Junk yard? That might not be a bad idea, especially if it dies during warranty. Then you can keep the spare indefinitely...

Yup, junkyard it was. I also plan on getting a few other parts for my e46 that are known to be curb kickers as we load the tow. Lol. But ya, a junkyard for that just in case moment

I'll start looking then. If you should happen upon one, feel free to PM me. Though you're in Canada maybe there's a way to get it to NYC (I'd pay all expenses + time, of course...).

It might also not be a bad idea to start a thread just for this. That way, if folks find spare tanks we can create a directory so we can all help each other out.

Just Replaced M56 Fuel Tank

Had a fuel pump failing, mainly occasionally making a very loud noise and high level of vibration you could feel at the underside of the fuel tank. Figured I would simply install a new $175 fuel pump over the weekend and THEN discovered the sad story regarding the Fricking M56 "hermetic" fuel module, with tank, filter, transfer pump, and fuel pump all one piece and serviced only as a $7500 assembly. At 161,000 miles I was SOL on the 15 year 150,000 warranty (which hopefully everyone knows about now) yes, it does cover it 100% regardless of what state you live in so don't let the dealer BS you on that.

At any rate I got a very low mileage M56 salvage tank and a lifetime warranty for a total with tax of about $2,000.

Was going to have our local independent replace it, but they were a little cranky about putting used parts in a car, so I ended up spending 2 days and doing it myself.

I work slowly and methodically, and could probably do it again in half the time, but it is done now. Worst part was maneuvering the filler pipe up into position and ended up pulling the diff and rear suspension to give enough clearance. I was up on 4 jackstands, and if you are on a full lift with standing room under the car you might not need to do this. If you are going to tackle it, pull off the RR wheel and the access covers, then look at what you are faced with prior to proceeding. Everything else is relatively easy, just time consuming. Don't forget new bolts for driveshaft (both ends) and half shafts to do it by the book. Also diff fluid.

Car seems to run smoother now too, so might have been a side benefit. Last service dealer could not find anything wrong though and of course the pump was quiet while it was there.

Might want to buy that salvage tank now, I have a feeling low mileage M56 fuel tanks will start getting more difficult to find in the future.

cheers

(aside from the emissions legality question) That could be extremely important information for anyone considering replacing the M56 fuel tank with a plastic tank and serviceable pump, filter, etc. I had considered doing that before finding a good low mileage M56 tank, and would have not known about the need to use an M3 or equivalent fuel pump. There are a whole lot of odd M56 unique components is what I am slowly discovering. Including (I think) cylinder head, exhaust (for sure) and other parts. Have to say the car has been great otherwise, but the sealed tank is complete BS to get a Fed and CA credit for something that ultimately is not "green" by any common sense definition.
