Default Coil-over conversion electronics fix project

Hi everyone. I'm an old audiphile new AR geek. I've launched the air springs in favor of the Stasis msports. I have been following the a/s delete thread for a while. I am experiencing the same thing as RMcQ where I cannot turn off the esp. I keep finding posts that say that you just unplug the suspesion module and "every thing" works, but I'm not finding that to be the case.
I have alot of experience with the VAG system architecture and some GOOD Dealer contacts who are willing to help. We have a few ideas on how get everything communicating normally. If I can get all the coil over converts to help me compile some data. I think I can help us all enjoy the good ole steel coils without any issues. Any and all information or experiences will help. I'm loving the new suspension but I want everything to work properly, and I'm making it my mission in life to do so. (hopefully it doesn't take that long)

I need the following info.

Model year
Transmission
Engine control module part # and soft coding, any stored DTC
ABS module Part # and soft coding, Any stored DTC
Front brakes, 8 pad(HP-2) or 4 pad(FNR-G60)?
Xenons? Y or N
Headlamp Leveling work?
Does your ESP stay off when you shut it off?
Any other issues you have noticed?

I am in LA and I have a VAG-COM. if there is anyone in LA has an coil over conversion too, lets talk.

Default paging dan farmer....

Dan has an 01 with the stasis setup here in the bay area and can shed some light here.

I think your area of interest will be in the ABS controller. Also you may want to look at 6 speed vs manual as there is some highly interactive communication between TCU and ABS.

Default Re: Coil-over conversion electronics fix project

Just had mine done today. Just drove back from Escondido to Encinitas with no problems or warning light showing up.
Turned of the ESP and found that it goes back on after 40MPH,
and i tested that several times.

Got to drive back to LA tonight for work. Will see if anything else comes up in the drive.
PS also the shop that did the C/O conversion didn't have a VAG-COM. just on did the displug of the air ride module at the compressor.

get in contact with me at
idahocartel@gmail.com
this week i am free as of friday

Default Let me clarify "the project"

I believe I have figured out how to fix theese problems allready. The issue is the ABS control module looking for communication from the J197 SCM and not finding it. Most of the abs control modules cannot be recoded like the ECM and TCM can be, however some can. Most of us though, will have to replace it, but compared to the coilover investment, it's minimal. As info is posted we can find the Hardware and coding pkg that works. But I need people to post it. The other issue is the headlamp leveling system which has it's own CM and sensors independent from the SM, although it appears that when the SM is unplugged it disrupts the power to the headlamp module disabling it, which may or may not be an issue depending on the spring rate you have chosen for the vehicle. I am running 650F/750R, so there is not much dive or squat, so my headlights aren't going to do much leveling. That being said, I would still like the system to function correctly.

There are a few cars floating around with A lot of money invested in them, and they will all agree it sucks to have a MIL on or not be able to turn the ESP off.

When all the dust settles, I would like to post a part number for an ABS control module and the correct software coding values for the remaining CMs on the network so that you will be able to approach your repair facility with this info and leave with the car working as it should.

So to further clarify I don't need light shined on the subject, or peoples thoughts, unless they include actual diagnostic data(not trying to be a jerk, but I've already read ALL the threads). I'm not selling anything. I'm trying to get everyone working together to fix a problem.

So then, lets get it done. If you don't have access to a VAG-COM, try to find someone near you who does, you can read out all the info I requested in 15min. If you are around LA, I have one send me an email.

Interesting. When I disable my ESP, it stays off.

Default alrighty then

Sorry to take so long to respond. Work has been kicking my butt. I'm definitely interested in this project!

Model year: 2001
Transmission: manual
Engine control module part # 4Z7 907 551L (not the original ECU)
soft coding 06712
DTCs for evap control system and misfires (16684 and 16689)
ABS module Part # 4Z7 907 389
soft coding 06395
DTC 01310 can't find level control module (because it's been removed)
Front brakes: Stasis
Xenons: Y
Headlamp Leveling work? apparently not
Does your ESP stay off when you shut it off? See below.

My basic set-up includes Stasis Motorsport suspension and brakes, plus the AWE Stage 3 kit. The level control module has been removed. Before the module was removed, ESP would turn back on briefly after I turned it off. Now it stays off till 40 mph, then turns back on. I've done a few 4-wheel burnouts in the snow and it stayed off then. I didn't keep spinning the tires for many minutes at a time, but I promise to try that next winter.

As for the headlights, VAG-COM cannot communicate with module 55 - Xenon Range, though i do have xenon lights.

If there's anything i can do to help, I'd be glad to.

Default Re: alrighty then

Perfect, Thank you!
Anyone else?
I ordered a few used ABS control modules. I'm going to try them out and see which ones can be coded and will be accepted by the other powertrain modules. We can get the ECM and cluster to think it's an A6 2.7T, but the ABS CM is not cooperating. Then I'll figure the lighting out. We're thinking that the power circuit runs through the harness for the suspension Module. we are going to try to make a jumper harness to bypass the module. First I'm going to situate the ABS/ESP though.

It would be EXTREMELY helpful if we can get the info I requested from your vehicle. You might break the case!
