Its safe to assume that my occasional suspension lights again eminate from the ABS module.

The over pressure charge exceeded, it a very seldom WOT symptom in a 3-4 shift. I've pressure tested and nothing is leaking It may just be time for new 710N valves as this is what I'm using and they have about 50k miles on them. I stil don't want to put in the Forges again..bad Karma.

Interesting that a few faults all point to the ECM.. perhaps just a loose connection, but this may have something to do with the "Hiccup" I experienced yesterday. It was short enough that no specific code was given..I think.

If it has been a long time or if you just got the VAG-COM and never did it yourself before these codes could have been stored for a long time and may not represent current problems. I know some people say you shouldn't just clear codes without IDing problems, but if I were you I would just keep a record (you already did with this post) and clear 'em all. Then drive around with VAG for a while and see what codes if any creep back. I'll bet in will narrow down considerably.

See the below post for the explanation.


I know the excessive boost code was from last week. I get it now and then. I also know the ABS nodue code was from my last Suspension CEL of two weeks ago. These are recurring themes that I know of.

What I'm finding interesting is the intermitant communication with the ECM.. as a recurring theme in a few areas. This alone explains the 'hiccup' of last evening.

But I'm planning a dealer visit. I will clear them this morning and give them the print out and scan again prior to my visit in a week or so.

Intermittant commo problem could be caused by a loose or dirty electrical connection somewhere

I recently added the tire monitoring to my ProDiag, but looking at your scan results, there may be some that I'm missing...

"ECUs we should be polling?"

There is only one ECU in the car.

Perahpaps you are referring to what Modules or channels you should scan?

VAG-COM has an auto scan feature that automaticall scans the major components. You can then pick an choose other componets as well, like the auto suspension system.

UnoDosTurbosQuattro

4B,Audi A6 C5,
01,02,03,06,08,15,16,17,18,34,35,36,37,45,55,56,57 ,67,75,76,77

Not all of these are present in the AR, and some are model year dependent.

Becasue I have a 2001, I edited the line to only include:
1,2,3,6,8,16,17,45

These are: Engine, Auto Trans. ABS, Seat Mem, HVAC, Steering wheel, Instruments, Interior monitor
(Skipped #15 airbags just to be safe)

2002+ models have more addresses active. Ross-Tech has a good list here:<ul><li><a href="http://www.ross-tech.com/vag-com/cars/applications/100a6.html">App Chart including allroad (A6/C5)</a></li></ul>

then it will scan every possible module, the scan takes longer that way, but you can be sure everything is covered.

want

"17963 - Charge Pressure: Maximum Limit Exceeded". It should be caused by the exhaust bypass valve can not be opened properly. The most possible reasons should be the N75, or the hoses connected to N75, or the bypass valve get stuck.

Just my opinion.
