Thanks Marko! Now I have the part number. Is the VIN # programmed into the DME in a 02/97 ti? At some point between 97-98 they started programming the VIN in the DME does anyone know when that started?

What I've found when you remove the secondary air pump it will throw a CEL code on the first cold start but the secondary pump only works on cold starts to help burn off the emissions until the cat is heated up. So you can remove the secondary air pump but you need to warm the car up and then clear all codes before taking it to SMOG. As long as the car stays hot the pump won’t turn on.

not really sure about the programed DME vin #s.. but one thing I wanted to remind you is that you should select your specific vehicle from the drop down menues on RealOem.com - I belive what I atached was already pre-selected for my 99 318ti.
Jsut to make sure you got the right part # you may wanna go back to the main page of realoem.com & select a 97 318ti.

true, but wont you have to reset the CEL every time your car is cold (like every day you get into it)?

also, your DME will store data for some time... so even if you reset the codes & then try and pass emissions - you will fail (I did).
you need to go through a drive cycle (I heard about 25-50 miles) after you've reset all codes - and only then you should go & try to get inspected.

Yes you will have to reset the codes. The CEL bulb is out of my car so I dont have to look at it everyday. But you are correct before I go for emissions again I will need to reset the codes and go for a drive.

I'm still sh!tting it cuz i still have to get my car inspected at the ref.

[the governor]

Hugo have you cleared your CEL?

I talked to Joe at the M shop, really nice guy. he told me what I need to do and he is going to help me out. I need the 7 digit part number and vin from a manual '97 ti active package and he will re-flash the DME with the program from the manual on my DME. Does anyone have a '97 active 5 speed that would help me out?

when you clear the codes you also clear the emissions info. your car collects sensor data and when they hook up their emissions tool if there isn't enough info it will say so. that is not a passing condition.

My pump fails but i've found that i can clear the code, drive enough to get emissions data and pass without my code coming on. Actually last november the code came back on within a mile of the inspection place.

Update: I disconnected the EGS (automatic transmission control unit) and three transmission related codes disappeared. But now I have a new code P0600 serial comm link malfunction. I can not clear this code, it comes right back. I believe P0600 is caused by the DME looking for the EGS. I think I may have to recode the DME. The M Shop was unable to recode the DME possibly because the EGS was still connected and the DME wouldn’t except a manual program with the EGS connected.
If any can shed some light on this it is greatly appreciated.
