I recently have come across a coolant leak on my 2003 e46 325i. It only leaks once it’s built pressure. After taking a look from underneath the coolant is quite literally everywhere. And the highest point of the leak is on the upper radiator hose. I replaced the hose, still the same issue, I...

Hi everyone, I have a automatic 2003 325i sedan that has been giving me non stop issues since i bought it just over 3 months ago. Constant repairs almost "EVERY" day. I have so far replaced 3 hoses because they all blew at some point in the last month, all seperately. (Part numbers 11531436410...

today I had the rear light error come on the dashboard. I've looked into it and found that one of the 2 left rear light bulb connections has corrosion on it. I've noticed in the past water pooling in the plastic tray below the light, however it wasn't excessive. Just looking to find out what...

Hello, I have a 2000 316i that has a coolant leak from the top of the expansion tank. It was replaced a while ago and ran fine for a while. Now I have the same leak as before. It only leaks after I shut the car off and let it sit overnight. However it sometimes leaks enough to trip the coolant...

Hi Guys, I'm a little lost on this one. I've installed two new rear diff bushings (along with new front ones the first time) in my e46 320i over the past year and both have leaked after only a few days of being installed. I used a bushing press tool which I'm confident wasn't pressing on the...

Hey guys, Couple days ago I noticed my oil level was very low (blue arrow), so I added some fresh oil (around 1.5 L, or 1.59 quarts) to the engine (red arrow). Then the following days I immediately found very large oil stains on the floor, so I went under the car and spotted that oil was...

Hello everyone, Just recently bought the BMW E46 2.2 petrol (170hp) from 2004. Atm got 97k miles at the clock. First day after I brought it for the diagnostics, there was no errors at the computer, but the mechanic discovered small oil leak from the top of engine which is causing that it sits...

It's weird. Im just going to spill what was done and things that appear wrong for me. Everything started with leaks and I figured maybe engine is overheating and has too much pressure in the cooling system. When engine is warm upper hose is stiff and hot, lower hose is cold. INPA readings are...

I just got done switching out my suction hose and return hose (the hoses that connect directly to the power steering reservoir) for my power steering system on my m54 330i. I’ve been having a bad leak and thought I switched out the right parts only for the leak to continue to leak lol. I found...

Hi all, I have a 2004 E46 convertible with the GM transmission. We have been tracking down a tranny fluid leak and it appears to be coming from the connection between the tranny Oil Cooler and the hose that goes to the Transmission. There are O-Rings in there that are likely the source of...

I have an '03 330i, and I've bled the cooling system a few times now. Either I'm an idiot, or there's a leak somewhere in the system. I want to rule out any leaks, because I don't see any coolant on the ground and the coolant light doesn't come on. The cooling system is the only trouble I've...

Recently did some work to my diff including replacing the halfshaft/output seals. After a while I noticed they were both leaking but I can't figure out why. When installing them I used a bit of diff oil as lube and just slowly hammered them into place with a mallet and blunt piece of metal. Only...

Hi everyone, I took my baby home from my dad's house, approx 20-40 mins away from my house I parked in my garage and switched the engine off and had a panic attack because i started hearing a loud hissing air leak (like a tire flattening) that i was unsure about, and it wouldn't stop, knowing...

Hey Everyone, Two weeks ago I bought a 2003 330xi and I have already replaced the spark plugs, and fixed rust and now I am working on the Ebrake (just waiting to find a kit for cheap) Anyway my car is leaking oil because one of the holes for the oil pan going into the block is stripped. Is...

hello, it recently rained for the first time and I found a small spot of water on the drivers side front carpet. In the following days all my windows fogged up very easily and there were even drops of condensation on some of them. I'm planning on checking the vapor barriers as I suspect this may...

Hi all, my first post here. I bought a 2004 325xi Touring about a month ago, and have read hundreds of useful posts here. Anyway, I dropped the pan on the GM tranny, replaced filter and gasket and refilled with Redline D4. I know that stuff smells bad, have been using it for years in my VW...

My 328i seems to defiantly have a coolant leak, but I cannot seem to find out where it is leaking from... I can see (what I assume is coolant) sitting in the bottom of the engine bay (on top of the plastic cover) I don't feel any coolant on the upper or lower hoses, so where could it be coming...

Pretty new to the E46 game. I have a 2004 325ci convertible. As I was driving back home today, I see white smoke from the hood, and smell as sweet burning smell, and the engine was overheating. So I pulled over and saw that the coolant was boiling. After I let the car cool down, I see that I was...
