See how to replace the combination fuel filter/fuel pressure regulator on an E46 BMW with an M54 engine. This would be the 325i or 330i models with the 2.5L and 3.0L engines that used a returnless type fuel system. The older 323/328i models had the M52TU engine and those used a return type fuel system. I will cover those models in a future video.

When I first bought my E46, my CEL was on for P0171 & P0174. I fixed multiple vacuum leaks and replaced multiple vacuum lines but that still wasn’t the cause. After doing some more research and digging around, I gave this fuel filter / pressure regulator a shot since it wasn’t very difficult to replace. My CEL finally went off and the codes went inactive. I would’ve never imagined this fuel filter was the culprit but it makes sense. I guess my filter was so dirty and clogged up that it was causing an restriction creating a lean mixture. I guess sometimes you just gotta stick to the basic maintenance stuff.

Be sure to change that little 3” piece of vacuum hose from the filter to the hard plastic line. My codes were the result of it completely disintegrating, coming off the fuel pump and suckin’ air.

To minimize the fuel spilling out I shoved a golf tee in each line as soon as it was removed from the filter. Worked great but a small amount of fuel coming out is a given however I didn't need a pan to collect the few drops.

Thanks for the videos changed mine today :). Just a littel side tip if you want no fuel to come out of the lines you can run your car to a quarter tank "maybe even half" jack the car from the front as high as you can so the fuel stays at the back of your car. leave your car like this for a couple hours "i left mine for 24hrs" There should only be abit of fuel left in the fuel filter that you will need to worry about.

I changed filter last night and engine sounds as it should this morning--a slight beautiful hum!

Hi, lots of great info on your videos. I measured 50psi fuel pressure on my E46 and it doesn't fluctuate with acceleration. It drops if I manually apply a vacuum to the small hose that connects to the F tube. I don't feel any vacuum coming from the f connector. Do you know what the vacuum measurement should be? Is the vacuum source supposed to come from the bigger jet pump hose? If so, what reading should I expect at the larger hose in case it is semi/clogged?

+david Crawford So be aware that you have a different fuel system--a return style where the fuel pressure regulator is separate from the filter. I'll be doing a future video on this one because a friend of mine has one that needs replacing, but it's actually extremely simple. You'll see the pressure regulator (it's got a vacuum line going to it) and you'll see that there is a sort of metal retaining clip holding it in. You pull that out and then just pull the regulator out (if you determine you need to change it).

You've got the M52 engine. It's basically the same thing only the M54 has an extra 0.2 liters of displacement (and a few more horsepower), the different fuel system as I mentioned, and instead of the solid aluminum skid plate underneath the car you have 3 tubular braces in a triangular shape. Also you've got the pre-body lift front end. No xenon cat's eye headlamps.

Thanks for Sharing.........Just FYI....When replacing hose clamps -fuel, vacuum, coolant etc. I try to use the "Pressed" OEM Style "Worm" Clamps such as Oetiker (OEM) or Norma/Gemi (They have pressed threads) The clamps that you installed have the "cut holes" for the threads. A BMW Mechanic explained that those type clamps(with the holes for threads) damage the hoses because they cut into the hose. As the hose ages it is more likely to fail sooner. I presume that is why BMW uses them. They can be found if you look for them. I know that AutohausAZ carries them.

Hi, your videos are a great help for the M54 owners(including me). I have a situation now, and I'm really curious about your opinion about it. Let's start with the start. More than a year ago I discovered that I couldn't empty my fuel tank more than 1/8th of the meter. When the warning light came on, my car died(with a left range of 80-90km). It happened 2 times before I knew I had to fuel earlier, and the problem was 'solved'. Half a year ago, the engine check light came sometimes on. It was not always there, but just sometimes. It was throwing the codes P0174 and p0171. At first, i was looking for a vacuum leak somewhere. I changed the DISA gasket, the valve cover gasket(including new vanos), and the two Rubber boots at the intake. It was still coming back. I changed my MAF sensor, but this also not helps, and the last days its getting worse. After i fuelled the car completely up, it was really worse. At cold starts, its dieing directly 2 or 3 times. After that its shuddering and on 5-cilinders. It throws codes P1085, P1083, P0174 and 0171. Also sometimes the car is giving a whistling noise, coming from behind, that differs on the revs. After long thinking I will change my fuel pump and filter(regulator). I guess thats the only logically left thing, except of a closed/contaminated catalysator. What do you think?

Great video! I want to try this DIY on a 2004 330ci but had a bad experience in the past. I did the same procedure on a 04 325i and the car would not start after the fuel filter had been changed. I could not figure out what caused the issue so I put the old fuel filter back into the car and it turned on. My question is, could it have possibly been a defective new fuel filter? If so, then what's the part number for my vehicle? Thanks in advance.

Keyser is the OEM brand and you can find it for a better price on eBay. Can't say why the car didn't start in your situation, except that maybe you mixed up the inlet and return lines (at the back of the filter).

Turns out my fuel pressure regulator is not on the fuel filter, but at the front of the fuel rail. I say this because I've been getting a strong fuel smell under the bonnet since winter of 2021. I thought it was the injectors and replaced them all at a hundred bucks a pop summer 2022. fuel smell reduced somewhat but was still there after shut down. the stealer told me it was my purge valve, so I replaced it in march, a few months ago. mechanic who did my waterpump and thermostat last week, told me that the fuel smell is coming from the fuel pressure regulator and or the vacuum-like hose attached to it. the hose is really cracked. I'm getting the feeling that that hose carries fuel vapors from the fpr after shutdown? is that fpr difficult to replace? do i have to remove the fuel rail? don't particularly want to do that again.

Got a question for ya. I just replaced my fuel filter in my e46 today, well going off your video the two lines on the back of your fuel filter are/were reversed on mine because I just put them where they were before on the old fuel filter. Would the car still run with them reversed to know for sure if they were in the wrong placement all along and now even? Damn, I really didn’t feel like getting gas all over again even with pulling the fuel pump fuse and letting it run before replacing.

Hi, my 330ci has some sort of internal leak in the fuel system that causes fuel pressure to drop over time. I'm not exactly sure what is causing this but it seems to hold pressure for longer when the car has run for quite a while vs she drops fuel pressure quicker when she has only run a few miles (under the same ECT temp). Could it be a faulty pressure regulator that holds pressure for longer when it gets heated up from the heat of the exhaust ?

+frank j it's the check valve inside of the fuel pump. It goes bad over time. You can install an aftermarket inline check valve immediately after the pump for about $7 that will solve the problem. Search for fuel check valve on Amazon and buy a 10mm one.

If you have an M52TU engine you are supposed to have the bare fuel filter like that. The pressure regulator is separate. Watch this video on a car that has this type of system and you will see what it looks like: kzbin.info/www/bejne/oKLIl5KOpd9qhclh- Consult realoem.com and enter in the last 7 digits of your VIN number to find the exact part number for your car and then type that part number into google or ebay and you will see what the part looks like and then you'll know what system you have.

old question but still - if some of you have idle problems with cold starts with cold weather (below 13°C) and then when the car gets to temperature the idle is normal (and also when the problem goes away with cold start when the air temperature is warmer than 14°C) - THEN you have a problem with vanos on your M52TUB engine. The ar has special mode when the outside temperature is low, that it opens the vanos on neutral to build heat in as quickly as possible - that is why it is mysteriously occuring only when cold starting on cold day. On M54 this probably wont happen as it should have an electronic fix for that mapped in ECU. I am just writing it anywhere I can because it took me a lot of time to find the problem on miine, so you can sort out yours if it does the same :)

Hello, I have the same problem on my S54. Beast of an engine. BMW mechanics can’t find a leak and thought maybe carbon canister or I over filled the tank. Head me h even took it home as a road test. They looked at me like I was imagining things. It spewed gas on my driveway and road first time like a leaking line. Still stinks inside after running a while and can smell gas from the engine bay top left area in front of the driver but can’t see drips. Okay So I’m thinking the fuel pressure regulator may be faulty but maybe partly plugged the leak. Worried she may blow up one day as the engine runs hot. Getting it looked at tomorrow. Please let me know if you sorted out the problem, thanks and good luck.

@@osoyoosforever9643 I fixed my problem - the vacuum line to the fuel pump pressure regulator had detached. This caused both fuel to leak out of it AND the pump to run over the rated pressure (hence the negative trim - the computer was "backing off" the fuel delivery because of the extra pressure). I'm not sure if the S54 uses vacuum to regulate the fuel pump, but check your filter! Failing this, it will be a leaking injector seal or injector body, or a high-pressure fuel line into the injector rail - all serviceable parts.

Hi 50s kid, I believe you responded to my questions regarding fuel regulator but when I went to read it I received a message saying "message reported" and I don't see your reply anymore. i apologize for the error and was wondering if you can repost? Also want to clarify that my concern is that if no vacuum is present at the small F tube fitting, especially during idle, that defeats the purpose of the fuel pressure regulator diaphragm... Any help is appreciated since I suspect there should be a vacuum during idle
@50sKid
@50sKid 8 жыл бұрын
+George Santana I think I've responded like 3 times already. The fuel pressure regulator on the M54 is regulated to the atmospheric vacuum coming from in front of the throttle plate, which is very small compared to the manifold vacuum coming from behind the throttle plate. You're not going to see any vacuum at that F connector when at idle, because that vacuum is created by air rushing past that opening when it's going through the intake boot and into the engine. At idle, the throttle plate is closed, and there is only a tiny amount of air going through (into the idle air control valve). In other words, you can ignore it. If you have 50psi in your fuel system while running, then that is normal. The sucking jet pump increases manifold vacuum for the brake booster by acting as a one way valve.

The line on the top of the fuel rail runs from the fuel pressure regulator down under the body (approximately underneath the feet of the driver -- left hand drive cars), up along the side of the fuel rail and down to the CCV oil separator, which only has a little tiny tiny bit of vacuum. It's only purpose is in case the fuel pressure regulator diaphragm bursts, the gasoline vapors will be sucked into the CCV system and then into the intake manifold to be recycled.

@50sKid
@50sKid 7 жыл бұрын
It's a possibility. If your fuel pressure regulator diaphragm were torn, your fuel pressure would be low which could cause a lean condition but then again fuel would be leaking into that vacuum hose and getting sucked into the intake manifold which could cause a rich condition. So it's kind of tricky. Yes, a fuel pressure gauge would be the way to confirm that. What are your total fuel trims at 2500 rpm?

The jet pump inside the tank needs the return line pressure to work if the return line is weak the suction jet pump wont work.

Unlikely that it's the culprit for your misfire but still it's a bad thing because it causes a vacuum leak. So replace the vacuum line (preferably all vacuum lines, those cars are old and that rubber is crumbling 100%). If you got a single cylinder misfire it's more likely you have a problem with the ignition coil or spark plug of that cylinder (rarely injector failure). To test the coils, take a coil from a good cylinder and swap it with the cylinder that has the misfire. If the misfire moves to the other cylinder, you know you got a bad coil
