Definitely not a bad thing to try. Have you fiddled with the headlight to check it out? I installed Angel Eyes, and fitted some wiring badly, breaking the seal.

1) inspect the seal. Use rubber cleaning compound to de-dirt the seal/gasket. Attempt reseal. Check seal behind lamps (sometimes they unseat).

2) Replace gaskets...

No problem. I'm a newish owner of a 2002 JB e46 M3 SMG. Unfortunately, a previous owner in Nevada/Utah most likely let it bake in the summer/winter driveway, trashing all of the exterior rubber trim. Headlight trim included. So I've been going through the process of restoring all of that.

As a side note, rubber trim can get frickin expensive. The Quarter Panel Finishers (part 15)? $250 to replace. Mainly because the metal piece and the rubber trim are sold as one frickin piece. Bah!

Doesn't matter what it looks like. I've thrown out perfectly good looking relays that didn't actually work.

I keep a spare "known good wiper relay" in the glove box for when the one in use fails. You should keep spares of all your relays, really, but the wiper one is notorious for being a piece of poo poo.

The weird thing was, I pulled the biggest relay (black one in the underhood fuse box) and tried the wipers, and they still worked. Obviously, I pulled the wrong one, but the fuse box diagram doesn't show which relay does what...

I replaced my aux fan today. It works now! I can use my A/C again!

A word of warning though, the upper right bolt is a pain in the rear end. The bumper comes off easy enough, and that bolt comes out alright, but getting the bolt back in is a royal PITA. I had to remove the right kidney as well as the right headlight, and I still had to blindly put it in with two fingers. I suppose a magnetic nut driver might have worked, but I don't have one.

I have a question though: A few days ago I posted this picture:



I got a new aux fan thermostat, and the plug won't plug into that one either. Is there some trick to it, or so I have a damaged plug or what? I have it loosely in there, but I don't know if it's making the connection or not.

Also, if/when I replace the thermostat (I haven't yet) do I need to bleed the radiator afterward?

That one is bolt is a bit of a trick -- I got it with two 1/4" socket extensions.

Regarding the thermostat, I assume you mean the aux fan switch, but regardless you'll have to do it.

FYI for those with E46s who are underwhelmed by their A/C: Recharging the things is absolutely trivial.

I thought it just didn't have a great A/C system after having driven a few other imports with similarly disappointing A/C, so I just figured I was spoiled by American cars and their ability to blow ice cubes on a 115 degree day.

Turned out my A/C system was just barely at the lowest end of the "OK" section on the gauge when I hooked up a recharge kit on a whim, so I filled it up until the point the kit I had was marked as appropriate for 90 degree days and went out for a drive.

It still doesn't blow as cold as my older Fords did, but I'm fairly certain one of those was an R-12 system which I've heard always tended to be colder. Now I have notably cold air within a minute of starting the car and within five minutes can have the cabin nice and chilly even in a black car on a hot day.

The correct port to fill the system on an E46 is right in front of the compartment on the passenger side of the engine bay where the battery apparently goes in some regions. It took me all of five minutes in the Autozone parking lot and a $30 can of R-134 to go from getting kind of cold air with the thing set to 59 degrees and max air flow to now being able to comfortably use the "auto" feature as intended.

This also made me realize how badly I had been screwed by paying people to recharge my A/C for me on previous vehicles.

What recharge kit did you use for that and what were the pressure numbers? My buddy has a harbor freight kit for recharging and the fucker won't clip onto the ports.

Also, the compartment is known as the drug bin and I think the brake booster and other poo poo go on that side in RHD models. I dunno if batteries ever go there.

Speaking of A/C. After three weeks of trying to find a new R12 -> R134a adapter that fits the E36 and failing, I finally gave up and screwed the broken one back on and carefully charged the system. This time I was able to get it to hold the charge, thankfully.

Why are there so many different varieties of the R12->R134a adapter? You'd think that there would only be one universal part necessary for such a thing, but from my experience they are all slightly different. I drove all over town, checked at the junkyard, the dealer, every parts store in town and I was not able to find an adapter that fit my car.

At least I have cold air again.

I found a good trick for driving nuts/bolts you cannot possibly to start threading is to wrap them in scotch tape and jam them into a socket with another nut behind it as a spacer. I had one of the lucky early E30 starters that wasn't threaded and it is not possible to even get close to the upper one without taking off the entire intake manifold, but taping the nut did the trick.

Don't test drive one. That's how I got into this mess, saw the ad on craigslist, figured "what the hell, I'll go look at it". Oops.

I haven't owned it for too long (bought it today, actually :P), but I hear they're not as god-awful as you'd figure. Parts are expensive, gas mileage is not good (I've gotten 15 so far in some "spirited" driving :P), and an oil change is $100 if you DIY. That said, they're apparently decently reliable, and the common issues aren't too expensive to fix. This one has been very well cared for, and I wouldn't buy one without a complete service history.

The E38 and E39 represent the epitome of BMW to me. After that generation of cars I begin to lose interest very quickly. They're stoic without being as sedate as Volvo or as gaudy as Mercedes and Audi. The newer designs have their elements, but there's too much flash and attention-grabbing for me. Every time I see the new 7 series I think it's a Lexus. :(

I used a Quest brand kit purchased at the local Autozone. It's an 18oz silver can with a gauge on the hose. It has markings at 30, 40, and 50 PSI for 65, 75, and 85 degree ambient temperatures, respectively plus a chart on the side that seems to indicate not to take it over 55 PSI regardless of ambient.

The valve on the Quest kit sucks and it's easy to loosen the connection between the valve and the can while opening it. That spray is cold and greasy when it loosens too much. Once you realize to hold it in place it's a workable design, just it sucks to discover the hard way.

No, it's there, just so shiny so it blends into the hood.

I love the E38/E39/E46 era cars, the styling on the later ones is just perfect. I might have to spend some cash on the 01+ headlights to get HIDs and angel eyes.

I paid 16.3k for it, including the Bentley repair manuals for the 5 series (a two volume set, easily 4" thick each, not sure how you'd ever find anything in there), and two spare wheels, both brand new (one each F+R). Possibly a bit much, I've seen several 00s go for 15-15.5k, but this one was just perfect, great shape, mods I wanted, full service history, lowish miles (75k) etc.

Unfortunately (in aesthetic terms) I think pedestrian impact standards may preclude a return to the shark nose.

Plus I can't imagine that the shark nose is more aerodynamic and with CAFE standards being what they are every little bit of cD matters.

Did some minor work on the '99 M3 this week to smooth it out a bit. First, I was having some wheel vibration, so I went ahead and rotated the tires to see if I could eliminate it. Sure enough, vibration free on my commute.

Then, while it was up in the air, I swapped out the (relatively fresh, only 10k mi) stock-fill transmission fluid for Royal Purple Synchromax. There was an immediate and notable difference in shift effort and notchiness. Color me impressed.

Finally, I went ahead and Seafoamed the engine a couple times to hopefully clear out any carbon buildup on the valves and/or pistons. There was very little smoke, so I take that to be a good sign. No noticeable difference in idle or acceleration, but it was worth doing before I do plugs later this week.

Oh yeah, you can definitely get the suggestion, but you're not gonna have an E34 or even E30 style front going on.

I think the current 6 looks like rear end but that's probably because it looks really fat to me other than the nose. BMWs look so unfortunate these days.

Q: What does a E46 M3 travelling at 50mph look like after it is hit head on by a mk2 golf travelling at 80mph?

A: Probably better than the golf.

















Basically some dude hit me head on while he was trying to overtake TWO cars on a blind corner, the wrong side of two solid whites. In the dark.

I only saw him about 3 lengths ahead of me as I crested the corner, and managed to get the brakes on hard and keep it straight. Both belt pre-tensioners fired and so did the airbag, but I never felt like my face came into contact with it, probably because I was sitting correctly. There were no intrusions into the footwell and only the passenger door wouldn’t open. The engine and gearbox escaped under the car, and I think that’s what bore the brunt of it.

However the force of it meant two of my lower vertebrae did come together hard enough to break, and they decided to cut me out. This car didn’t have the lumbar support option and I wonder if it would have made a difference or not. I think the 4 star ncap is about right, I dont really think they test for 130mph closing speeds.


Anyway enough old and busted here is the replacement hotness:










2002 6 speed with HK and various other bits, including adjustable lumbar this time :). The steel grey is growing on me, and the 18"s deal so much better with crap road surfaces.

Now I just need to rig up a system of mirrors so I can check there are no idiots on the wrong side of the road round blind corners.

I never really thought about it before, but the consultant told me that NEW seatbelts can stretch up to 15cm in a high speed impact, other dudes old mk2 golf one stretched so much his head hit the windscreen somehow. He was well enough to appear in court recently but he was in intensive care for at least 3 weeks, whereas I just had to lay flat in osteo for 2 weeks then they let me home. I only had light bruising on my hips and hardly any across my chest and shoulder.

PROTIP: Think about what sort of belt you wear, or like me now, make sure you tuck it either under or over the seatbelt without disturbing that from your hip bones. Otherwise the seatbelt will bend the steel buckle using your abdomen as a backing plate.



Also anyone know how to calculate what g force I went through? As in I did 50 to 0 in about less than 6 feet, but the other dude was doing 80 so I don’t know how to factor that in. The consultant was ex air force and he said that to see spinal fractures in helicopter crashes, when they whump straight down into ground, they have to be in-excess of 30g for a point of a second on the occupant, that sounds really high and obviously mine is a car with crumple zones and lateral deceleration.

Assuming uniform deceleration, you experienced 12.4gs. If the deceleration was non-uniform (very likely), the peak deceleration was higher than that. That's still very bad gs, however. The human body can withstand much more gs in the vertical direction (such as when you're seated in a car or helicopter) than it can front to back. But of course, since the vertebrae are oriented up and down, the kind of injury it could sustain in this crash would be different.

e: I had my math wrong, now I get 14.2gs.
