Audibug:
Yes, I have the Ross-Tech cable with the newest firmware and software.
I will follow your directions, and see what I find.
Before and after replacing the low pressure fuel sensor error, car starts
but after a couple more cranks. Otherwise, car seems to run OK and accelerate OK. Just prefer not to have these codes come up.

This is what Ross-Tech tells me:

If you've already replaced that sensor then chances are there's problem
in the wiring or connectors between the sensor and the ECU. Also check
any relevant ground pr +12 connections. Another possibility (IMO less
likely) is that the ECU is defective.

There's also a TSB covering this fault code, number 24 09 01 (2019426/2)
dated February 4, 2009, but it only applies to MY 2008 and 2009 cars,
not this 2005. Sadly, it does not give any useful info, but instead
says contact the Audi Technical Assistance Center.

My old key yesterday would not come out of the ignition for like couple of minutes. I had replaced the batteries like few days back.
what would cause this? happened for the first time.
I ordered another key from the dealer, charged me like $121.
The service dept. wants like $100 to reprogram the keys.
I assume this programming has to be done by the dealer only??
pl advise

bballfreak

I did what you asked using the Ross-Tech cable.
The fuel pressure seemed pretty steady. I was not sure if you had to do one group at a time, or can do all three groups on one screen.
Again, I think one of them said it was adapting?
I did capture the data for each group members.
what do I have to do next?
I did also clear all the codes.
pl let me know
thanks a bunch

i have the same problem with my 2006 A6 3.2L. Did you find a fix? Could you pls share some useful info?
BTW, TSB covering this fault code seems to be 24 07 01 2010890/3, Jan. 9,2007.

bballfreak

No, I have not been able to get fix this code. If you do find a fix, please also let me know.

I would post the test data of group 103 and 106 here. The numbers will tell a lot about your car fuel supply low and high pressure systems. It will guide you to where the problem area is.
I would take the reading of 103 and 106 with fuel pressure regulator solenoid connector connected and disconnected.

i forgot how to do thius test using the ross tech cable and software.
thanks a bunch

Where did you guys buy the cable from and what type of cable is needed to work on the C6 a6?

Sorry from the ignorant question.
