Subject: Error Code chart
Message-ID: <[EMAIL PROTECTED]>

Does anyone know of a link for error codes? I bought a
Bavarian Motorsports code reader for my 95 M3 and
recently bought an adapter to use it with an e46. 
Unfortunately, the chart that came with my reader
doesn't work with the e46, though the reader does
work.

Thanks,

Paul

Message-ID: <[EMAIL PROTECTED]>

The only "drilled" rotors I'd use on the track are the ones with cast-in 
holes... 
Drilled rotors will at best 'only' crack... (remember titanic?  It sank due to 
the drilled rivet holes and crack propagation...)

Anyway, disc brakes work as heat sinks... transferring kinetic energy (forward 
motion) to thermal energy (heat)... the more mass the more energy they can 
absorb... (critical for track work)
But big heavy brakes = more unsprung mass (= bad) so racers 'drill' them to 
reduce weight...

The only road cars that I have ever seen with cross-drilled rotors coming from 
the factory are Porsche 911s, of which I never owned one.

The reason for slotted rotors is two fold:
1) for road cars it becomes a wear indicator (the slot goes away, the rotor is 
under min. thickness, and time to use as a paperweight...)
2) On tracked cars the slots act (theoretically) to break up the boundary layer 
that can form if, lets say, the stock pads are over temp.... on lets say a 
late-summer track event (like PCA's August Summit Point) going into turn 1 and 
gently, but firmly stepping on the brake pedal and having nothing happen. (firm 
pedal, no stop = not a happy driver) 

There's been much discussion on this topic on the P-car site, and there a few 
good links I'll try to dig up that can further explain some of the 
misconceptions and phenomenon's...

Gents,
The M3 (1999) had a couple of episodes of not wanting to start this weekend
while going for the Calif. smog check. No starter engagement, just
instrument lights. After a couple of pull the key out and re-engage the
clutch all was well. This morning also a clean start with no issue.
I'm thinking the clutch interlock switch or the inline battery fuse may be
cracked.
Real Oem shows the fuse, but where is it. I want to inspect it.
Also I can't find the clutch interlock switch on Real Oem. How hard is this
switch to change? Does the clutch pedal have to come out?

Thanks as always, Kevin

I had a similar experience with my 1998 M3. It was the starter.

 good point.  Had the damn same thing in my old toyota pick'em-up truck.
Starter connections were corroded.

the fusible link (at least in my car a 95) was near the rear of the battery
cable under a black rubber covering - find the narrow gauge wire and trace
it forward until you see it go into the rubber covering and then look for
the rectangular bump.  I can't remember if it was in the trunk or under the
rear seat.  I have the cable laying in the garage.  I can look tonight if I
remember.

I just removed my cable from the race car and happened to find the fusible
link a few weeks ago.  I had wondered where they hid it prior.

Can't help you on the interlock, I don't think 95s had it.

Thanks for asking.

My family and I are fine. Some of my customers cars and homes were not so 
lucky, and if you have seen the news, several people north of Nashville lost 
their lives as a result of the band of wicked tornadoes.

I forgot to add, I do have the Big Boy clutch stop, but it's down as far as
it will go.
