Started my car this morning and the code EEP_2 code showed up in the instrument cluster all gauges we're dead. Turned the car off and restarted and code went away and instrument gauges we're working fine. Anybody have any idea what this means? Couldn't find much anything in regards..help whats the EEP 2 code?

looking through the bentley right now. so far i see that eep = the main circuit board controlling the instrument cluster.
Maybe it was "Eep Hour!" (Garcia reference!)
its the noise you make when you find out how much a new circuit board costs.
from what i have dug up on other forums it means you have a bad instrument cluster. you will have to have it replaced and the bentley manual outlines what to do to make your milage show back up on the new cluster. if you get a used cluster make sure that it has less milage then your car since the process of restoring the milage takes the higher of the two values.
Thanks 2K! Well it hasn't reappeared since, hopefully it NEVER comes back..the last thing I'm looking forward to is having to change my instrument cluster :/

This just came up for me tonight. Sure enough, once the car warmed up I restarted her and it went away. Anyone have any clues as to what causes this?
I am fairly certain I have a very occasional short that I think is somewhere near the head lamps. When it rains sometimes the turn signal will do the fast blink thing indicating a lamp is out and if I jiggle the lamp fitting it stops. Maybe these are related?
I JUST got the same EEP 2 indicator on Monday. Same thing, gauges we're dead. Shut it off, restarted, and it's been trouble free since. I dunno...
Where do the letters show up, on the mileage screen?

I'm surprised how little information is available on this issue. Now that's cooled off in TX it's a [near] permanent fixture on my dash. I'm about to - though afraid to - buy a new damn cluster. Has any other information on this come out?
When the cars were new, instrument clusters were being replaced under warranty all the time. I guess you'd have to do some ten - twelve year old searches for posts on the matter (try roadfly.com, as that's where most of us signed on before 2002).
My black car received a new cluster when the service interval lights counted down to an "oil service" about two weeks after the oil was serviced (while still under BMW maint.).
The cluster is easy to change, removing only two (2) screws (be extremely careful not to scratch them up, or anything else) and a few painful facial contortions. It can be slipped out to the left with the steering wheel still in place. It's possible to release the two (three?) cable connectors blindly, and they cannot be interchanged accidentally, having different number of connections. There is a coding plug you transfer from the old one to the new one, but beyond that I have no more useful information, as I've never needed to replace one myself. I only pulled my own 01 cluster out to put a bulb in the "SPORT" socket (illuminated by Daniel's controller).
Just doing a quick look around the net and a few things keep being repeated:
1. Power source on the back of the onboard computer needs fixing
2. "CPU" dead (needs replacing)
3. 2 NiCd batteries in cluster need replacing
4. Ground for instrument cluster in inner fender well needs tightening
These supposed fixes seem to point to a power or ground issue of an internal processor.
It would be interesting to run clean power and ground to the cluster and then a cooling spray on various components to see what happens. Cold days were almost always mentioned when the cluster stops working.
Might try resoldering the EEPROM legs on the cluster as well.

I've read through German, French and Mexican forums (on top of the usual suspects) and didn't get quite as much info as you seem to have found, Monolith. I didn't even find out there were batteries in the damn thing.
@Randy - I'm squeemish about sensitive plastic things. I removed the steering wheel last time I pulled it out to give me room to not break anything...
I'd take my list with a grain of salt. I didn't confirm any of the stories, just tried to find how some people "fixed" it. The guy trying to replace the "batteries" ended up destroying his cluster while taking it apart and just buying another one.
It's interesting to note that the odometer gets overwritten on the cluster. The mileage is stored in the EEPROM (which some say originates the EEP errors). If you follow my link, one fellow with the MB suggested wiping the EEPROM and reprogramming it will cure the problem.
Ran across a German site that will fix the EEP errors for 139 Euros.

They probably just reflow the solder on the EEPROM and send it back.
Here's a link describing the failure as an EEPROM (mileage) failure:

Here's a data sheet showing how the EEP1, EEP2, EEP3 nomenclature is used as storage locations for EEPROMs (just click on the document image for PDF):

Did you guys ever figure this out?
My cluster has started doing this after my service shop insisted on doing a computer upgrade for my DM-TL fault as they thought the "available upgrade" would magically cure the CEL.
Now my cluster shows the EEP_2 error intermittently. It seems temperature related and more frequent on cold mornings. After the error displays, I have to go through the cluster reset function in order to get the speedometer to read accurately again. Otherwise it reads ~20mph higher than true road speed.
I wonder if I need to bite the bullet and get the cluster repaired.

A bit off topic, I think the instrument clusters on the s54's is the only CAN-BUS related item in the car. Kinda funny they blended the old e36 tech with the newer e46 stuff to make it all work.

And another EEP-2 code. First time I have seen this.
All clocks dead, apart from the speedo, and EEP-2 displayed on the odometer.
Switched off and restarted and all working and reset.
I will monitor the situation and get INPA on the case when I get time, will post any results here. Fingers crossed for now.
